I recently bought a USB to RS232 adapter (it works fine). My question is: How can find out which com port it is using, except by trying all of them and then finding the one that works. I have a older Thunderbird GPS 10 MHz frequency standard thet requires a RS232 interface to talk to it (for setup purposes). The first thing it askes me is which com port I'm using(1-16).
View 8 RepliesA few days ago I installed a USB 3.0 card (to be precise, this one: 2-Port USB 3.0 SuperSpeed PCI-E Controller Card - Free Shipping - DealExtreme). It uses the very common NEC PD720200 USB 3.0 controller. I installed the required drivers for Windows 7, and the card worked fine for the first day or so. but not since. Whenever I plug in a USB 3.0 external hard drive, I get a false "This device can perform faster..." message, as if I had plugged the drive in a USB 2.0 port.
The external drive I am using is a Western Digital MyBook Essential 1130. It is definitely a USB 3.0 drive, and came with the required USB 3.0 cable. While the USB 3.0 card was working, I got full-speed transfers to the limit of the hard drive's ability, about 90-100 MB/s. Now I can only get USB 2.0 speeds (33-34 MB/s). Windows insists I have the drive plugged into a USB 2.0 port even though it is plugged directly into the USB 3.0 card.
Things I tried so far: -rebooting and complete power cycle. No difference. -plugging the drive into one port or the other. Also no difference. -Looked in Device manager.The controller is recognized as a USB 3.0 device is using the proper NEC drivers.
Other info that may be important:
-No overclocking settings in use.
-I made sure the cable was plugged in all the way. It's in as far as it can go, but the ports will still only act like USB 2.0 ports.
I might as well throw the card away if it is only going to act as a USB 2.0 device.
My USB ports on this Gigabyte mobo are SUPPOSED to be all USB2.0
So, how come I still get "This device can run faster" messages in
my Windows 7 64 bit home premium installation?? I went to Gigabytes webpage and installed the chipset drivers for Windows 7 on there, but still get the same message when I plug in my Corsair 4GB jumpdrive.
First a little background:
System - Dell Inspiron 546, Windows 7 Home Premium x86 64 bit.
I'm an Engineer/Designer/Machinist and work with CAD/CAM programming. After I create the programs with the toolpaths for my CNC Macining Center I use a separate program to transfer the machine control data to the CNC.
Here is my dilemma - Win 7 is not compatable with the old 16 or 32 bit, file transfer program I had been using with XP and Vista. I have found 64 bit programs that are compatible but cannot get the computer and CNC to communicate.
The problem I'm having is, in the file transfer software I need to set the Parameters such a Comm Port, Baud Rate, etc. I cannot determine the port assignment for the usb connections. In XP and Vista they were Comm 4 and I could find that in Device Manager/Ports. Win 7 doesn't seem to have a listing for ports. How do I determine this.
I have five USB 2.0 hub successfully operating over 20 devices. As these fail I will upgrade to 3.0. Anticipating more 3.0 devices and a 3.0 motherboard in the future. Why do they only have four ports? If I am mixing 2.0 hub with 3.0 hub's should I plug in. In a certain order
View 2 Replies View RelatedSo I installed some weird file and it like disabled ALL of my USB ports, hwo can I get them to work again?! Both my keyboard and mouse are USB and I don't have any regular ones, any way I can fix this through my 2nd partition using WinXP? im using the Win XP partition to ask this right now, my Win7 partition seems to run fine like when it happened I thought it froze but it didn't because the wifi signal went off from my USB wireless adapter and my mouse+keyboard adapter both light off as well as my DVC 80 capture device. The file I ran was 'libusb-win32-filter-bin-0.1.12.2.exe' from a package I downloaded in a zip called 'iHackintosh iRecovery Package for Windows & Mac' and I REALLY DONT want to restart my computer

I have no control in safe mode.Basically if it deals with windows, i have no control. Only before windows loads.
View 3 Replies View RelatedI noticed recently that for some reason,my USB ports aren't being identified as 2.0 ports, but I know they are. My computer is an ASUS CG5270, Specs: Core 2 Quad @ 2.4 GHZ,8 gigs ram, 750GB hard drive. I tried going into the device manager and uninstalling everything under "USB", and then restarting and replugging everything in..no luck. I found some Fix for Windows 7 SP1...no luck. Whenever I go into the Device Manager, there are two ports ( I think they're ports) listed as "Enhanced", with the rest as "Universal". I keep getting errors when I plug in my external HD that "this device could perform faster". (I also get another message telling me that the drive needs to be formatted, but it works anyway). I also get a "this device could perform faster" with my webcam, as well...

i'm using the x86 version of build 7000 and i'm very fascinated of how it works already in this beta-stage. but i have a strange crashing-issue from time to time that does not allow me further testing.
from time to time all of my usb-ports seem to block everything: my usb-soundcard stops working, my wireless-adapter, my external hd, everything that's plugged-in into an usb-port stops working.
it happens when i'm using my soundcard, videocard or both of them: playing games, watching dvds, browsing Internet, listening to music, etc.
when i'm trying to reboot, the os will stuck in the logging-off-screen 'cause it's trying to play the logoff-sound over my soundcard..
On my Dell Vostro laptop, Up until today I never had a problem but now when I plug in my energy monitor to a USB port I do.. I have a mouse plugged in one port. If I plug in my energy monitor into any of the other 3 USB ports it installs a USB to serial port at the next higher com number. Its up to com 18 now. If I unplug and replug it in again it will find USB to serial com 19. It just keeps going up. How can I reset it back to 3 or 4.

View 2 Replies View RelatedI am not going to tell my problem or trouble but rather to tell what I had done based on what I found out from other responses to "related issues" subjected above.I just thought that I must do this for the sake of others, brothers and sisters in Jesus Christ wanted to go back to the threads that his but I am not that fond of using the search fields and somehow my google search results on this lappy is quite differ from the one i got on the usb-troubled lappy that i used to log into sevenforums. i have read through just about 10 of the related result on sevenforums but not one of them is the one i found out earlier.anyways, what i did was: uninstalled all usb listings in device manager and then just shut down the lappy, unplug all cables including power cable and went out for a smoke. a few minutes later, came back and plugged the power cord and turned on the lappy. and somehow, windows auto-install everything and since the lappy is wirelessly connected to the internet like always, it also download and install everything.then i plug the main cause of the problem (microsoft 5-button intelligent mouse) and wait for the driver update wizard to complete; and now everything not only seems working fine, BUT actually working fine now.

View 6 Replies View RelatedI just installed Windows 7 tonight and thus have moved from the Vista forums to here
But of course if everything were going smoothly I wouldn't be here. Now here's my problem, I'm trying to open ports for some of my programs but I havn't been able to. I've done it many times before in Vista with no trouble. I've tried disabling the firewall to see if that worked but it didn't.
Now here's where it gets weird. When I was in Vista I'd use Open Port Check Tool to check if my ports were opened correctly, it always worked. But now when I try it it tells me that my ports are closed, even basic ports like 80 and 21 keep getting:
Error: I could not see your service on 76.68.106.153 on port (80)
Reason: Connection timed out
is there a program that can show me the exact ports that an aplication or all the aplications on my computer use, or is there another way to get the information.
View 1 Replies View RelatedIm using windows 7 RTM x86
I want to close some opened ports.These ports are 135 and 445.
So, I try to close/block these ports using Windows Firewall. ( with advanced settings )
I created inbound rule for closing port 135(TCP) (as you can see attached screenshot )
Also I applied same step for UDP.
but, when I scan my pc's opened ports using Net Tools 5 program ( open port scanner tool ) , it found port 135 as open.
I created rule and blocked/closed port 135 but Net Tools says : Port 135 still open.
This is risky for me.
How can I close this port correctly ?

I have 3 USB ports but only one of them is working (OS Windows 7 64 bit.

View 5 Replies View RelatedLately some of the usb ports of my computer are not working properly: any device connected to them is not recognized. The problem appeared after I triedunsuccessfully to recover data from a damaged usb stick using umptool2090. This is how the ports appear from the Device Manager (it's in Italian, but it should be understandable):If I uninstall the usb controllers and re-install them automatically (using the device manager), the ports start working, but the problem reappears after rebooting. My motherboard is an Asus M2N78-LA (Violet6) and my operating system is Windows 7 home premium SP1. What can I do?
