I've had my ASrock 939 Daul Sata-II for about a month now and have had no problems with it. Rebooted a bunch of times and everything was fine. I recently went out of town for 4 days and shut down the computer since no one was home, came back and powered it up to find that neither my mouse or keyboard were working. I checked my KVM and it had no power (Power goes to the KVM thru the Keyboard line) So I bypassed it and rebooted and got keyboard control and power, but still no Mouse power. I tried everything and even reformated thinking it was a USB issue (I've got nothing better to do lol) Well still nothing. For some reason, that I do not know of, I am able to use USB devices such as my digital camera, USB CD rom drive, USB floppy drive, and even WEBcam but it well not power a USB optical mouse. I am able to use a USB trackball mouse but neither of my 2 Optical mice well get power to them. If they do it flickers and then goes off.

Could this be a power supply issue? or maybe something with the motherboard?
 
are you using an extension cable? this made my asrock usb stuff corrupt everything. broken contrlollers and ipod... until you get rid of the extension cable

try newer nvidia drivers from www.guru3d.com or newer drivers for non-nvidia at asrock.com
 
That board has nothing but problems with USB devices. It's it's only downfall really.


I don't have anything to suggest for the problem... Except for when I was having USB problems, a full re-format and re-install. Helped me...
 
Are you getting a message saying that you have a High Speed USB device plugged into a non-High Speed USB port? In the device manager are you seeing the dreaded yellow "?" next to your USB controller? I would go to ASRock and download their latest USB drivers because the ones that you got with your disk may have been corrupted. Sounds too like you may have shorted your motherboards USB controller or something because the mouse is using USB 2.0 to power it, check all connections and what not.

Are there any other problems you have come across in that time. I just purchased and setup this board last night so I want to have a contingency plan for everything possible.
 
Thread resurection because I had similar problems. Only, instead of not turning on, mine would not turn off even when I shut down the PC.

Locate the pin labeled PS2_USB_PWR1 next to the purple parallel port. It comes with the jumper on pin 2+3 which is +5VSB (standby mode) it keeps devices on if the power supply supports a 2 Amp or more standby current.

Most of the USB issues I have seen (including my own) have been fixed by setting teh jumper to pin 1+2. This turns off standby mode.

Tell me if this works. Like I said, it seems to be the fix for a few problems.
 
Thanks for the info DeadlyAura.

I had problems with an Asrock 775i65G, modem and Num Lock lights were constantly on, seemed to work fine until I plugged in a Creative Zen MicroPhoto when the PC just powered off alltogether.

Changed the jumper and all is well.
