I have a DSE usb mp3 player. When I plug it into the PC's usb ports, Windows XP says "USB Device Not Recognized: One of the USB devices attached to this computer has malfunctioned, and windows does not recogonise it. For assistance, click this balloon"

When nothing is plugged in, I have
USB 2.0 Root Hub
3x USB Root Hub
3x VIA Rev 5 or later USB Universal Host Controller
VIA USB 2.0 Enhanced Host Controller.

When I go to the device manager, the mp3 player shows up as Unknown Device. I've plugged it into the rear USB ports, the same thing happens.

Then when I plug in the usb drive, it appears as an unknown device too.

BUT
when I stick in a normal usb drive FIRST, that gets recognised as a mass storage device. THEN when i plug in the mp3 player, it is also recognised correctly.

So what could be causing this?
mp3 player then usb drive: both are not recognised
usb drive then mp3 player: both are recognised.

Have you tried the MP3 Player on another PC and get the same results ?

Ive installed the latest usb drivers for my motherboard, but that doesn't change anything, if that helps. I'm using SP2, but so is my friend's computer.

See if it makes any diff?
