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.
Code 43 Windows has stopped this device because it has reported problems
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.

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.
- An external device is not working when plugged in to a USB port
- All devices are working normally when plugged in, but the Unknown Device warning persistently pops up, and an Unknown Device is showing in Control Panel -> Devices.
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?

2010-09-09T16:00:01+00:00 I have an external USB drive that will fail to appear sometimes when I reboot. If I go in and remove it using Device Manager, turn off power at the device and then turn it back on and reboot, it will mount and works fine. No code 43 message appears.

2010-09-06T23:01:18+00:00 I join the ranks of the frustrated. Although I'm not suffering from the BSOD and can boot into Windows 7 successfully, I have an unstoppable pop-up that claims that: "One of the USB devices attached to this computer has malfunctioned, and WIndows doesn't recognize it."
There is no device connected to my machine, yet there is a USB port that doesn't work anymore. I can't uninstall it since it keeps reappearing on startup and yet it just reports an "Unknown Device" that needs troubleshooting.
Click on the Unknown Device and get this in the properties window: "Windows has stopped this device because it has reported problems. (Code 43)" No device, nothing stopped and unable to stop the most annoying popup that continues flashing in the notification / task bar until I open it and keep it open for the duration of my session. My problem may be different in that the death of an actual USB port could be to blame. But I too have tried all the suggestions including rewinding to a restore point, HijackThis, etc. etc.
I keep glancing over at my gorgeous Ubuntu 10.04 laptop as I grumble along with Windows 7 (Home Premium) problems and feel like I might just snap at any second, scrub the boot and escape from proprietary software license land for good. I hardly play the heavy processing games anymore anyway, which is the only reason I refrain from the permanent move.
