I have an Asus A7V600 Motherboard. When I first tried to use my onboard NIC I recieved an network controller error. There was no driver to be found. So I unplugged all my USb and rebooted, lo and behold it worked.
After about a month ..all of my USB devices have stopped working.
No matter what I do there is no USB on my machine. and i cant get it to install.
I have tried enabling and disabling USB in the Bios.
Nothing.
Can anyone help?
This was working about 2 weeks ago and then it stopped. and i have not changed anything.

Borrowed from Johnwill:

Unplug ALL USB devices.
Open Device Manager.
View, Show Hidden Devices.
Uninstall all devices under USB Controllers.
Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.
If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

When this is done, reboot TWICE.

Reconnect the USB devices and see if they're recognized properly.




And try the latest drivers as well. That would be the VIA USB 2.0 Host Controller drivers AND VIA 4-in1 driver package from the ASUS site.

I have removed all storage devices and rebooted twice. There is no USB devices listed at all. When I reboot and connect all USB devices nothing detects.
No USB shows up in the device manager.
I am at a loss. I hav installed all the drivers for my MB and still nothing. :(

If no USB is listed in Device Manager then it must be disabled in the BIOS. Go into the BIOS and make sure it is enabled. Also there might also be another option thats alled Enabled USB Legacy Support - this is not the option in the BIOS I'm talking about, there should be a USB enabled/Disabled option. USB Legacy probably should be disabled for this as it can occasionally cause an issue.

I didn't find the USB option in the BIOS originally. I dug a little more and there it was disabled. :( Now everything works just fine.

Thanks guys. :D
