This maybe the same or similar to ManOMullet’s issue.
Whenever I connect my new Sansa Clip+ to my XP V2002 SP3 with all the latest Microsoft updates, the system refuses to connect it up as a USB device. The Setup->System->Hardware->Device Manager shows the USB port with the message: “This device cannot start: Code 10”. I took the Troubleshooting advice and uninstalled that USB port. I plug it in, it finds it as new hardware, munges for a while and then tells me that it is having a problem during hardware installation. The Device Manage shows the same message again: “This device cannot start: Code 10”.
However, when I attach this to an older XP only up to SP2, the device attaches immediately and works perfectly.
I am limping along loading from this second computer, but I will need to be able to attach the Sansa to this computer because it is the one connected to the Internet.
