Well I hope someone can help me with this b/c I'm stumped.
I was loading something called USB Command verifer and I accidentely started the installation program for my sound card drivers when all of the sudden, my computer froze. Nothing moved, CTRL+ALT+DEL brought up nothing. I waiting a bit, and hit the reset button. Again nothing happened, so I hit the Power switch. Upon restarting my computer, none of my USB devices worked. Windows detects all the controllers and hubs. But I'm guessing refuses to power it or something. I checked the settings for the USB controllers so that it could shut off my USB devices to save power, that didn't help. Installed a few patches, that didn't help. Now I'm some what lost for ideas.
I know the devices still work because when the computer is starting up, it detects it when it is posting and the green status lights are on. but as soon as Windows starts to load it turns off.
Anyone have any ideas?
I should probably add I've tried different ports, different devices, I've installed the Windows XP USB 2.0 patch. and still nothing.
maybe try going to device manager, uninstalling the usb drivers, and then having win xp reinstall them with "add new hardware" in the control panel?

I did something similar. I removed all the USB controllers and hubs and restarted the computer. They reinstalled fine, but still nothing. What's also odd is that the device that I originally had plugged in, my Logitech cordless comfort Pro, was uninstalled some how in the initial reboot, I'm guessing that's because it's as if they are no longer plugged in.

I've got the same problem, i recently (2 weeks ago, making system restore impossible) upgraded from Windows 98 to Windows XP, i now have no USB ports recognised by the computer and no A drive either! Both of which as far as i know are working fine. any solutions?

Tried doing a system restore, but windows was unable to restore any of the points.
As for your problem TashF, I think yours might just be installing SP1 or the usb patch microsoft released. mine was a clean install of XP.

just a quick idea... have you checked the usb options in your bios? make sure USB is enabled. PNP enabled.
plug in a usb device, (preferably not keyboard/mouse) and go to device manager, right click and choose scan for hardware changes. see if it finds the device.
try update driver option from device manager for the USB device, select a location, and direct it to the driver for USB 2.0. let it install and see what happens. sometimes you have to tell it what driver to use manually. (it's microsoft :) )
also check the website of the motherboard manufacturer. there could be a bios update / controller driver update available. could help.
Goodluck!

Thanks Zach, but pretty much tried all of those, or some variation of it. I'm certain it's a windows thing. cause when my computer is booting up, all the lights are on my USB device and even BIOS detects it. But the minute windows starts loading, the USB device shuts down.
I'll try a USB pen drive and I'll try doing that update driver option.
I've been trying system restore, but it seems that windows can't get any of the restore points to work.
