USB Hub Port Power Surge?
Nov 2, 2012Well I just got a brand new medion computer (4GB ram, 1GB nvidia graphics card, dual core i5 3.0Ghz processor, etc) about 3-4 weeks ago and have had no problems till now. The problem is when i bought the computer i got a mouse and keyboard which worked with it till about 2 days ago. I have 3 USB 2.0 and 3 USB 3.0 slots and. 2 of each type are on the back and the remaining 1 of each are on the front. Now, anytime i plug both the mouse and the keyboard into the back i get a warning message at the bottom right saying "USB hub port power surge" or something along those lines and neither device works. But if i un-plug them both and plug back in the keyboard, the keyboard works. I have tried restarting my computer. I have even tried turning the computer off, un-plugging it from the wall. Than holding the power button so it quickly flashes on and than off again (I hear this resets usb ports Link: Reset of USB port after probable power surge ) I than plug the computer back in and start it up but still neither devices work unless i unplug the mouse. I have also tried plugging in memory sticks and other devices and they work until i plug the mouse in beside them. Every now and than they un-expectedly decide to work together and than stop as randomly as it began.

Mar 16, 2012So I had a power surge a few days ago and it fried a lot of devices in my house including my external HDD controller/charger so I removed the HDD from it's case and mounted it in my PC. So far so good, it was recognised in BIOS, my primary Master and my former ext.HDD Slave, boots up ok but when I go in the explorer I don't see the partition. I encrypted it with BitLocker when it was used as an external USB HDD.Now when I go into Disk Manager the disk is seen as online with 465 GB of unallocated space. Is there any chance I can recover the data on it ?

Setting Can Change To Shut Off Power To USB Buses / When Power Off PC?
Jun 9, 2011I use my PC for audio production and I have a few external controller devices that are USB powered, for example a midi keyboard. I recently had to build PC due to a theft....long story short after building the new PC I've noticed that my USB buses have continual power to these external devices after I've powered down the PC. My old windows 7 PC did not do this. Is there a setting I can change to shut off power to the USB buses when I power off the PC? Or is this a hardware issue?

View 1 Replies View RelatedRandom Power Off / Power On / Reboot Events
May 2, 2012Over the past 2 years my PC has been afflicted with random power off/power on/reboot events.It will go for months without these and then have multiples of the events in a day. (I had 8 of them 3 days ago.)I assume I have a hardware problem, but nothing has been found and I'm grasping at straws.The time between power off and power on is several seconds.I had assumed this rules out a software cause, but maybe I'm wrong. I know Windows can schedule a power off, but can it tell BIOS (or something) to power back on in a few seconds?I know blaming the power supply is a much more simple explanation, but then I'm left with explaining the intermittent nature of the failure.

Mar 17, 2012My computer wouldn't shut down, even with holding in the power button, and so I just let it run out the battery. Then it wont turn on. I tried holding down the power button to clear out any charge that might be remaining. I have managed to get it back on, but I have to make a connection at the clip where you plug the power button ribbon into the mobo. Also, this is the second time I have had to do this. The computer works fine afterwards...or seems to anyway.

Feb 17, 2011Last night my new laptop arrived (XPS), still getting used to windows 7 etc... but i thought i would watch something through my t.v. Plugged HDMI cable in back of laptop straight in to t.v, changed the source and straight away i had a lovely sharpe picture of my deskop instantly.... or so i thought
im getting the middle part of my screen fine - but it is cropped so i cant see the tool bar (its too low) and the desktop icons are only veiwable if i move them closer in screen! Ideally i want to have identical screens on both so i can use both at sam time, but currently i can only view either or atm? and the t.v one being crop means i can use it as a computer (No toolbar etc..)
I could figure this out on XP but windows 7 seems beyond me atm!

USB 3.0 Driver With 2.0 Port?
Aug 1, 2011To all the computer geniuses out there, I guess this isn't a windows 7 problem but it's about drivers.I have an Asus K53E-B1 with Windows 7 64bit. It comes with 3 USB 2.0 ports and that's it. I went on the Asus website today and found USB 3.0 drivers update.I can't just download those drivers and use them and expect USB 3.0 performance when I have USB 2.0 ports right?

USB Identification - Which Port Is 2.0
Apr 5, 2011I have a quick question about the USB ports on my computer. I have a screenshot hosted here on Flikr: USB | Flickr - Photo Sharing! Of the 5 USB's that are listed, one is a USB2. Is the USB2 Enhanced Host Controller a USB2.0 port? I am looking because I am going to buy an audio interface and if I have a 2.0 in there then I will get something a little better 'cos I want as little latency as possible when recording vocals.
There is one other thing also, if it turns out that there is a 2.0 port, is there a way to physically differentiate which port is the 2.0? I have 3 USB's on the back and 2 on the front of my tower. At the moment I don't know which is which and do not know what to physically look for when I look in or out of the case.

Port Conflicts
Dec 2, 2009I use my computer aboard a 47' Sailboat primarily for navigation and communications. As such, I run multiple external devices. To name a few:
WiFi Cards (2)
GPS
Pactor Modem
Iridium Satellite Phone
Verizon Aircard
Telcel Aircard
You get the picture. I was unable to accomplish a very simple task using VISTA, to wit, being online with my Verizon Aircard and using one of the WiFi cards to access my wireless printer.
I finally downgraded to Windows XP and this is never a problem anymore. A Verizon tech once gave me an explanation of why this couldn't be done in VISTA, but unfortunately the explanation went over my head.
Does anyone know if this problem has been fixed in Windows 7, or does that OS have similar problems as VISTA handling multiple communications devices operating simultaneously on different USB ports?
Cannot Open A Port
Dec 16, 2009I have spent the last two hours trying to open a port for a remote control application.
I have tomato 1.27 running on an asus wl500gP router.
I am running windows 7 ultimate
i have an Arris voip modem through comcast
The problem is this, i forwarded the port correctly in tomato yet the port is still closed. I have tried the following:
Enabling DMZ
Disabling windows firewall by either the control panel or through services.msc
Enabled UPNP in the application, it opens the port according to tomato yet external port testers still say its closed
reset the router and pc numerous times
hard reset the router
Hooking PC directly into cable modem
I believe that this is strictly a windows 7 issue now as the router is out of the equation. The only security software I have is Avira free edition, windows defender, and (disabled) windows firewall.
Can anyone give me help as to why I cannot open a port? It would be greatly appreciated as I am leaving for a trip in 36 hours and would like to be able to remotely control this application.
