Usb Root Hub Problem
Jul 30, 2009
I'm using the build 7600.
It all started when i inserted a SD card. It didn't work so I inserted the SD card on my camera and plugged it in by usb. The second I inserted the usb to my laptop my usb mouse turned off and my wlan just literally vanished(it wasn't even in device manager.) Usb root hub with exclamation marks appeared in the device manager.
I tried uninstalling them and letting Windows 7 install them again and wlan wont come back and the mouse wont work.
I also tried uninstalling everything below usb conrtollers and generic volume and still no wifi.
I tried installing the drivers from the manufacturer of my laptop after uninstalling the old ones and still none
I was able to get the wlan running again after uninstalling everything below usb controllers in the device manager I restarted my comp in the middle of it cuz wlan reappeared and if i waited for it to finish wlan would disappear.
Now Every time I plug in a usb device wlan disappears and everything starts all over again..

I've been running various Windows 7 Betas and RCs on virtual machines and spare PCs for a while with no issues, so when I got access to the RTM I was quite confident (probably overly so) to upgrade my laptop from Vista.
Right after the install (ironically enough, from a USB), everything was working fine, until I plugged in my iPod, which installed the apple driver successfully, then informed me that the device was unplugged before the USB Mass Storage driver installed (it wasn't). I proceeded to try the other three USB ports on my computer (all four worked fine in Vista, and still work fine in XP and Ubuntu). None worked. I tried a thumb drive with an internal LED, and it appears that the device receives power for about half a second, before cutting off. Running a system restore back to whenever they were last working fixes the problem, I can plug in a USB stick, and it works fine for a couple of minutes, then its useless again.
The chipset is an Intel GMA965 express series, using the most recent driver (8.15.10.1825, for RC1). I've tried rolling back to the Vista driver, and the Vista driver in compatibility mode, to no avail.
Additionally, I've tried uninstalling all of the "USB Root Hub"s in the device manager, and scanning for new hardware, and uninstalling all of the USB controllers and then scanning for new hardware, still no luck. The issue that windows gives is
"Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)"
For which a fix for a similar problem (albeit with CD/DVD Drives) in XP was to delete the registry key, so I navigated my way to
HKLMSYSTEMCurrentControlSetControlClass{36FC9E60-C465-11CF-8056-444553540000}
And was first told access is denied. I took ownership, fixed permissions, and it still refused to delete (although, in trying to check what exactly the error message was, it just deleted now, although I'm not hopeful it will help)
I've disabled every reference to USB power saving mode in every power profile.
Most recently, I've tried the most recent Intel Device Chipset Installer, which installed successfully, but makes no difference. I also tried the built in troubleshooter, which recognises the issue, reinstalls all the drivers, and tells me it works/doesn't work, and then either way, it doesn't work. Although the troubleshooter does identify if there is a device plugged in for two of the four USB ports, it tries to install drivers, and fails.
In searching the internet for the last few days, I haven't been able to find a solution (although I have found several people with similar problems, one the same, all of which unsolved)
I would really prefer not to do a clean install - the reason I upgraded in the first place was because I had far too many programs installed to make it worth reinstalling all of them. I'm open to downgrading to vista, if its do-able with a clean.

If I browse my Windows 7 PC via UNC (\192.168.0.x) on an XP PC I am unable to get a list of shares. If I Directly open \192.168.0.xShareName that will work perfectly.
I have a vista PC on the same network and that can see the root fine. The only thing that I can think of is that SP1 has done something. but not sure why it would only effect showing the list of shares. As a side note in the event log i see the "Software Protection Service" keeps stopping and then starting, I tried googling it but no one seems to know if this is usual behavior to check the licence or if it shouldn't stop.

I'd just like to upgrade my usb ports if possible I seem to have trouble with em.It says it has 6.1.7600.16385 (in 2006 so theres gotta be somethin better) installed I found a few downloads but they were actually older 5.x.xxx.

I upgraded from 32 bit to 64 bit, but when I used my back up recover program, all my files are on my desk top, and root c doesn't seem to contain doc and settings.

This caught my attention today when I was installing the newest round of windows 7 updates, and has me curious, can't say I've ever seen it before so I've looked around and it seems that it used to only be for XP. Any way, from what I can tell from the description it seems to only be needed if your running internet explorer, I don't use IE on this computer (my gaming rig) and don't see why I'd ever have to, I do most of my browsing on my phone, or laptop.

I have a HP mini, microsoft 2005 pretty sure its a Windows 7.Basically I pulled the battery out by accident at a bad time. I had left the laptop on all night. It has always been slow but when I opened it it was very very slow. I saw a sign from AVG, with a window box saying AVGDIUX.. an error message. I made a mistake and pulled out the battery.Now when I switch it on it only goes to a start up repair screen. It runs a check for problems, tells me it cannot fix it automatically and then offers to shut down the computer. Scan results are:
Number of repair attempts: 5
Session details
System Disk = DeviceHarddisk0
Windows directory = D:Windows
AutoChk Run = 0
Number of root causes = 1
[code]....
I switched it off and pressed F8 repeatedly at start up. I can get to the F8 screen with the different options. I tried to go to safe mode/safe mode with command prompts but automatically goes to the start up repair screen and then goes through the same process i.e. saying it is doing a check and then that it can`t fix it etc.

My Windows 7 freezes, ~once per day. Suddenly, with no slowdown issues prior to freeze or anything in particular. My installed programs list is short, and contains nothign suspicious. Updated Ad-Aware and AVG complain about nothing. The HW itself is fine, since a previous installation of Windows XP worked perfect.Didn't find anything particular in the Windows Event log, but I am not sure I know where to search

my netgear wireless modem and wireless network were renamed and all the passwords reset. Hard reset to recover. I am still getting browsers redirected daily. All three browsers each will give message that setting have been changed when opened. IE will say search setting have been corrupted and mandate Bing. Internet Options will be reset to custom levels without a reboot. I have installed AVG 2012 paid. No scan from various scanners will show an infected file except some cookies. AVG rescue disk scan found 13 password protected files that were renamed. Broke AVG and required a reinstall. Password protected files were back by the end of the day. AVG says there should be NO password protected files in their sub-directories during a rescue scan. Their solution is a wipe and reinstall.What is the safest process of doing the HD wipe and reinstall? Just plugging the thumb drive in got me all this grief. Is reinstalling files from the DVD the same process? If i try to access my old files am i opening myself to reinfection?

After installing Nvidia drivers, Realtek drivers, and JMicron E-sata drivers, I now have .log text files on the root of my "C" drive. Are these accessed next time I update the driver or can I get rid of them? I can't seem to find anything about these. I know they are there for a reason but I like things to be tidy.

My C: drive has two (non-system and non-hidden) folders which I do not think should be there - these are 'boot' and 'clean'. I do not think 'boot' should be there as I already have a system folder named 'Boot' which is identical to the 'boot' folder. However, I cannot remove it as the computer will not let me. I tried to delete 'clean', however I am unable to - it says that the item is no longer located in C:. When I open the 'clean' folder it contains a subfolder 'log' which contains one folder, which, when I try to open it, claims that 'C:cleanlog2011-08-12_18:29boot-repair07 refers to a location that is unavailable'. So my question is can I delete these folders?

The program works fine with Win 7 Professional and Home Premium. In XP I could just give full rights to the user and all was well. But with 7 Ultimate, even with full rights, the program cannot access the file. However, I've found that Ultimate has a security app called Applocker. I have been reading up about Applocker and the exceptions that you can use with it to free up files on the Root directory, but since the file is a .net extension (not on the exception list of extensions), I can't add an exception to Applocker.

I just did a custom install from Vista to Windows 7 with an upgrade disc. After completing the setup, deleting windows.old, and reinstalling all of my programs, I noticed that there were old folders on the C: drive. It is as if it didn't move anything from the root drive to the windows.old file.
I'm annoyed at myself for not noticing it sooner. Now I don't want to do another install since I spent all that time reinstalling the programs and configuring them for personal use.
I'm tempted to go in and just delete the old folders from the root drive, but I'm nervous. Honestly, I can't be certain of what should and shouldn't be there.
Is there anyway I can tell which folders on the root drive are leftovers? I thought about deleting according to the date modified stamp, but I'm not certain that is safe either.
Can anyone advise me? I really don't want to do another install of Windows 7, but I was pretty excited about starting with a true clean slate. I just can't help but wonder what else it left behind.

What I currently use is CCleaner & Advanced System Care. I guess what I'm asking, is there anything that is more on a professional grade? A power scrubber that small businesses would use? I want to clear out unneeded registry files, left over install files, left over stuff from programs I have uninstalled, just ...my technical term is "crap" left on the operating system hard drive. I am using Windows 7 Ultimate x64.

I have Windows 7 SP1 and I should only move the users profiles (without the default profile) and the public folder in a NTFS logical partition.
I should modify the ACLs of the root directory () of the logical partition to still have a coherent and stable system or not? If so, how should I modify these ACLs?

Recently installed Windows 7 64 bit on my main hdd (had previously had it installed as 32 bit). Now my back-up drive gives me this error. The back up drive does not have windows installed on it, and is not a boot drive. But when it is connected I get this message: "Windows root system32 ntoskrnl exe missing or corrupt." In order to boot on my main drive, I have to disconnect the back up drive.
I don't understand where to reinstall the missing file - if I put it in the Windows 7 files, won't that mess up my main drive?

I recently upgraded from WinXP x32 to Win7 Ultimate x64 and kept getting the:"Windows rootsystem32 toskrnl.exe is missing or corrupt" when attempting to boot.
My system:
CPU: Core2 Quad Q8300
Hard Drives:
Primary (System) = Western Digital 300GB 10,000rpm
Secondary (Data) = Western Digital 1T-GB 7,200rpm
*External cloned CasperXP backups for BOTH on matching HDs -- However the backup Sys HD is still configured w/WinXP x32 until I can get all problems ironed out.
Problem Discovered:Upon booting the OS is pointing to the Secondary HD as Primary,however, once booted the C: drive is indeed the intended 300GB and Secondary is the 1T-GB HD.
How Discovered:I needed to relaunch the OLD XP system to access some old Firefox Bookmarks so replaced Sys HDs. Had to reconfigure boot sequence to get OLD x32 OS HD to boot (successful). Saved Bookmarks and shut down. Replaced the Old x32 Sys HD with the New x64 Win7 OS HD. Then got the above error repeatedly. Played with boot settings and BIOS settings for an hour before identifying that the x64 Win7 OS would ONLY boot with the Secondary Data HD listed as the Primary Boot Device. Do note that the OS files are all on the 300GB Primary even as the boot sequence points to the secondary HD.
QUESTION:Is it possible to correct this situation WITHOUT having to do a clean install of Win7 x64 with the 1T-GB Secondary Data Drive disconnected, in other words doing a clean install with ONLY the 300GB Primary connected?

I installed Windows7 recently. I was changing permissions and accidently denied authenticated users to C drive. I was logged in as admin which is the only account. Now I cant access anythig in C Drive and cant execute any thing. I tried through safe mode as well but of no use. How can I regain access or reset permissions.

For some reason, Windows 7 has decided that files in my root directory C: are music files.In every other folder, I can click on Properties, then choose Customize, then choose "Optimize This Folder For..." and choose the type I want - Documents, Photos, Music, General Items. You know the drill. If I click on Properties when I'm in the root C: drive, I get a pie chart showing me how much space I have left and lots of other choices, none of which let me view my files as "General Items."I don't want to sort my files in my c: directory by artist. There are no artists. Stop being helpful, Windows 7, and thinking I want it this way. I want it to be General Items.How do I do that?

I dont use libraries and dont like the way that you cant have indivual folder views with them. So when I click on the start menu and have the links for 'music, pictures, video etc' i would like it to link straight to the root folder and not to the library

My pc is a stock Asus G53SX-A1, no hardware changes. Yet it says the reason I got a blue screen was due to hardware changes. My computer froze and rebooted during a video game. So I have been experiencing the classic startup repair loop and I tried everything I could find on google without progress. When I try to the option to fix the problem automatically it says it wasn't able to help and tells me the root cause is because there is no hard drive detected, and that if a hard drive is installed it is not responding. I can't detect in command prompt, but somehow I can see contents of it through BIOS so its really odd. When I tried to reinstall windows it says it can't find a hard drive to install on and I need to insert a drivers disk so I can set up the hard drive to continue. So I put in my Asus drivers disk and yet it tells me there's no drivers detected. I looked at the Asus website and all the downloads they have available are the same as on that same drivers disk it said it couldn't find drivers on. So right now my main problem is my pc doesn't detect that I have a hard drive at all even though I do, the same one the pc came with. This laptop has worked fine for almost a year and this issue just came out of nowhere, so any ideas as to why my HD would suddenly disappear in my computers eyes?

I was using the computer when all of a sudden it shut down. When I turn it back it on, it automatically tries to do a Start-up Repair. After several minutes, I get the message: "Start-up Repair cannot this repair this computer automatically." When I click on "View problem details," everything looks fine except for "Root cause found: Boot critical file D:CI.dll is corrupt." This happens every time I try to restart the computer. I've tried System Restore and System Image Recovery to no avail.
