I recently bought AGPtek® PC Wireless Gaming USB Receiver Adapter for Windows Xbox 360 Controller and it isn't working.

I installed the drivers that came on the disk. It didn't work.

I downloaded the drivers from the microsoft website. It didn't work.

I went into the device manager and found it listed as an 'unknown device'. I opened the properties and browsed through the drivers I could update. Each installation takes over ten minutes and tells me it's failed.

Please help. I've had a rough day and I came home excited to use my controller with my pc. I've been working at this for hours. I'm so angry I could kill.
