USB device trouble - wireless adapter not getting power?

by thefatsnowman / July 15, 2011 9:28 AM PDT

Hi all,

So I bought and custom/home built a pc based on the 3xs
radius p55 bundle (pre overclocked i5 760). The motherboard is a Asus
P7P55D-E, i have 4gb Corsair RAM, a 1GB Palit overclocked GTX460, 1TB
Samsung spinpoint HD. I'm Running windows 7 (64bit) professional. It's been working well until recently when a quirk developed. USB
devices that I plugged in would make the requisite noise, but would not
necessarily function properly.

The first instance was my mp3 player;
windows media player would not recognise it, yet I could still charge,
load files manually etc. I assume this was the first sign of the
problem. It may be unrelated I suppose.
Lately, my USB wireless mouse/keyboard would occasionally drop out, but replugging in would solve the problem.

However,
catastrophically, I unplugged my USB wireless adapter as I was doing
something at the rear of my desk. On plugging it back in, I get the
usual noise, it shows in the device manager, but I am unable to use it.
I've tried a brand new alternate, and the same occurs. The power light
flicks on, the noise occurs, and then the power light goes off. The
device shows in the device manager, is registered as correctly working,
the driver is installed, but again the wireless manager cannot 'see' the
device. When I remove the device, I get the disconnect noise.

I
have tried: re-installing the drivers, verifying that there are no (!)
by the devices in the device manager, uninstalling all USB devices from
the device manager then re-plugging in, re-installing the chipset... So I
conclude this must be some sort of hardware problem?

Any ideas? I am now at my wits end!

Blown USB ports are sad but not uncommon.

This is where I try PCI USB cards. 10 bucks or less around here.

Oddly I've now tried a range of other devices, including a webcam. Following this, the power light now stays 'on' for both wireless adapters, but the computer can't seem to 'see' them, insomuch as neither finds any wireless networks and the wireless manager(s) says no device found. However the device manager still shows the device, and I still get the USB sounds on plugging in and removing.

So it's time or money?

Here I know to install a PCI USB card fast since the repair will climb fast if we let a tech tinker to see if they can get it to work again.
