Windows 7: PC suddenly not reading USB components

PC suddenly not reading USB components [resolved]

This is starting to tick me off. Last night there was a power outtage (and yeah, I know how silly it is to not have my PC plugged into a surge protector) and when I turned on my computer this morning I found that any device that was plugged into a USB port was not functioning.

This includes my wireless adapter, mouse, and webcame. My keyboard is connected via ps/2 and it works fine. There's obviously power being supplied via the USB ports (I've got my cellular charging right now), and the mouse and wireless adapter work fine on my laptop.

Not sure what the problem is here, tried restarting the PC a number of times to no avail. Some insight would be very useful.

This is all on a Windows 7 machine, check out my specs for all the essentials.

EDIT: I rearranged my devices and was able to get the mouse to work. However three of the USB ports are still not working and the wireless adapter is showing up as "malfunctioning", despite being in perfectly decent shape and working on other computers. I don't have the disc, so I'll probably have to jump through a few hoops to reinstall the drivers. Will update to see if that fixes it.

FINAL EDIT [[Fix]]::: Disabling the USB Root Hub in the device manager was a temporary fix at best. Three of the ports remained nonfunctioning, and today when I had need of a flashdrive the transfer rate was horrendous (three hours for 5gb of files).

Looking into it further revealed that all that had to be done was disconnect the PSU from the wall outlet for a couple of minutes and then reboot. From what I understand this causes the mobo to reset, as it still receives power even if you've powered down your computer and are still plugged into the wall.

Now it's back at full capacity, just figured I'd update this in case anyone else finds themselves stuck in the same boat somewhere down the road.

Cheers,

If you have installed Windows SP1, try this:

I haven't gotten around to getting SP1 yet, mostly because I've heard mixed reception. I'll give it a go once I resolve this problem.

So the way I can see it, two USB ports out of my five are working the way they're supposed to. However I can't use any of the other ones, they don't read anything that's plugged in. And whatever I plug into the two that do work (with the exception of the mouse), a window pops up saying that the "USB device is malfunctioning" or it's "unrecognized" so the drivers won't install. This has happened on everything I've plugged in (including my iPod, a 360 controller, the wireless adapter, etc).

I'm starting to get really frustrated and pissed, actually.

I'm sure it's a great program, but I can't use it because I don't have internet (I burned it to a disc, tried to run it from the Windows 7 machine to no avail), at least not without the wireless adapter. Which I can't install. The driver install requires that you plug it into the PC before you can continue, but since the computer reads it as a "malfunctioning" component, it doesn't work and I can't continue with the install.

oh right a see what you mean, have you tried going into device manager and un-installing the driver for the wireless adapter then rebooting and seeing if windows corrects itself and re-installs the driver?

Yeah, that didn't work. Also tried downloading the driver from Linksys, burning it to a disc, and then trying to install it via Microsoft's crap "driver update" option. Didn't work, because obviously "the driver you selected isn't compatible with Windows 7 x64", despite being the 64-bit driver.

Thanks, I'll give it a shot.

EDIT: Is that an "offline" version? I unzipped it and it appears to just be the same .exe I downloaded before and tried to run on the Windows 7 PC. It didn't work because it said it had to download some files from Microsoft or something, and to try again once I was connected to the internet.

I'm going to try downloading the chipset drivers for the motherboard, maybe that will work. I'll post update in a bit.
