Why won't my system recognize my USB device? February 8, 2. 01. Oh my gosh!!! I have spent the last two days going round and round trying to get my laptop to recognize my USB mouse again.
It was working one second and the next it just quit responding. I thought at first that the cable on the mouse had finally given out cause it had begun to fray at the base of where the usb plug and wire came together. So, I thought, “no big deal, I’ll just plug in a new usb mouse”. However, when I did, the laptop kept telling me unknown device. I searched and read every forum I could find on the subject. They pretty much all said the same thing, i.
Plug new mouse in another computer, plug other usb devices in port, plug other mice into the usb port, etc., etc. And my problem wasn’t just one of the usb ports, it was all three of them. However, I finally determined that external storage devices such as an external hard drive and flash drives would be recognized so if that was the case, the usb ports weren’t totally fried, right? So, why wouldn’t my laptop recognize a usb optical mouse? It was driving me CRAZY!!!!
Finally, I found an article where someone mentioned to shutdown the computer and UNPLUG it from the power supply, wait a few minutes, then plug it back in and turn it on. The solution couldn’t be THAT simple, but I was at my wits end and it wasn’t something I had tried so far. Figured it was worth a shot. HOLY MOTHER OF YOU KNOW WHAT!!! That freaking did it!!! Are you kidding me? AAAARRRRRRRGGGGGHHHHHH!!!!!!
I wish I had seen that article first. It would have saved me two days of unbelievable frustration and countless hours reading and trying to figure out how to get it working again. I’m happy it’s working again and just had to share. Unplugging from the power supply is certainly something I’ll remember going forward.
And from there I have been using Windows Update, Slimdrivers Free, to install the majority of the drivers. Some I found from searching on Google using Hardware Ids to find the right driver.
It's weird for Audio because if I run the Win. Windows UPdate finds the driver for audio, and audio works through my headphones. Then, after a restart everything stops working and it says there is no driver found for audio.

I tried cancelling the Win. WIndows Update could take over, but the restart revealed that it didn\t work. Then leaving the Win. Windows Update, audio still doesnt work after a restart. So Audio is still a problem.
And of course the Unknown Device is still a problem. I've tried CPU- Z and Belarc Advisor to see what hardware I am using, well thats not totally helpful anymore because it doesnt show anything related to my current problem now. I've tried other paid (trial) driver updaters, but you have to pay to use their software and I dont want to buy something that actually doesnt work and then having to try and get a refund.
