USB 2.0 Lockup

[bladephoenix]

I am currently operating a Gigabyte GA-8PE667 Pro mobo, which is an Intel 845PE chipset mobo. It has 6 USB 2.0/1.1 ports - 2 at the rear, and 4 by a supplied rear bracket. The rear bracket, obviously, connects to corresponding sockets on the mobo.

I am running 4 USB 1.0/1.1 devices connected to the computer at all times:

Zip drive;
A scanner;
A printer;
The USB reciever for the ATI remote wonder.

I also have a USB 2.0 MP3 player.

Now, here is the odd thing: Everything runs fine when I attach the rear bracket to the mobo. However, I wanted to make use of my TT Tsunami's front USB connectors, so I unplugged two ports from the rear bracket, so I can plug in the connectors for the 2 in the front. Everything still boots up fine...everything is still working normally when I plug in any USB 1.1/1.0 device into the front connectors.

But, when I plug my USB 2.0 MP3 player into ANY of the ports, Windows 2000 just freezes up -- mouse is even frozen. I rebooted and unplugged the front connectors, and...VOILA...works again. I was a bit confused as why this could be, since front USB ports are simply cables that carry the signal to the mobo...how can they stall the computer?

Anyway, I am out of ideas...I have W2K SP4, and the USB 2.0 drivers are up to date, and I don't know what else it could be. I just left the front connectors unplugged for now until I find out what is going on.

Any thoughts on what is going on?

Check the connections of the front usb connectors on the case. Quite often I have had cheap cases with wires running and wrongly connected. Since your 1.0/1.1 works it is doubtful that is the cause, but still re-check the data/power +/- is correctly connected.
