Essentially, my PC won't recognize my GoGear Opus MP3 player (or iPod nano). However, I am using a USB mouse and keyboard at the moment with no problem. I had this same problem on this PC when I had Vista. I upgraded to 7 hoping this issue would be solved, but it is still there.

I was having the same problem with my ipods. I then, just by chance, decided to use a different cable and to my surprise, this fixed the problem. Both cables appear identical and both cables are original apple ipod cables. I was able to use both cables in my previous computer. However can only use one with my new computer running Windows 7. Hope this helps.
Makavali,
I had code 43 problems with my usb ports until I found a thread on MSI's website. My front panel usb ports connected to a 9 pin usb header on the motherboard. Only 8 pins are needed. If pin 9 has a black ground wire then remove it. I didnt give this fix much hope but it fixed my problems! Good luck.

People on this thread seem to be having two separate problems.
I'm not affiliated with these forums in any official way, but things might go better if we separate the two problems. If all your devices are working despite Unknown Device messages, head over to http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/unknown-device-usb-error-code-43/27bb21a5-5c93-48ae-b2a6-eb55c7f9174e?page=1&tm=1336711036908 .
If you have a device that doesn't work when you plug it in, stay here. Can we do that?
I think I misread the regedit instructions and removed the Upper and Lower Filters entirely. Now the computer will not boot. I have downloaded the trial of Windows 8.1 Enterprise x64 Eval iso and burned a disc with it. Are there any specific instructions to follow to make sure I don't mess up my forthcoming attempt at repairing my brand new Windows 8.1 installation? Oh, the original problem I was trying to fix was my GPU was in the Device Manager but reported that Windows had stopped it because of an undefined problem.
I have a GT70 0ND running Win8, and I had this same problem. However, instead of opening up my case to remove a pin, I moved my USB accessory (a Belkin Bluetooth USB dongle in this case) to one of the other available USB ports (the ones not part of the assembly described by Migarr above).
Worked!
