USB problems

[spindle]

I recently replaced my dead mobo with a new FoxConn something-or-other skt 754 nvidia thingy (I'd be more specific but the model number isn't exactly memorable).

I seem to be having problems with my USB devices since I moved to this motherboard. The specific problem I get most is that I have a four-port USB2 powered hub plugged into one of the USB ports on the back and into that I have a printer and a digicam plugged in.

I can have the printer on or the digicam, but not both. If I'm in the middle of printing and I happen to turn on the camera (which I try to avoid doing now of course) the printer dies and only a reboot will restore printing again.

This is probably a fault with the motherboard, but is there any way I can be sure? I'm running the latest bios, have installed the correct USB2 drivers etc. The power supply is a Tagan 450W so there is plenty of power to the system (plus the hub is powered separately too).

Ideas? I'm thinking maybe there is some kind of software tool that can give me an idea of problems or whatever?

Do they work plugged straight in to the ports?

Yes. Sort of. The problem in answering is that I have a mouse, external hard disk, scanner, digicam, and printer - which isn't all that much I don't think, but I only have four ports on the back and 5 peripherals so have to use the usb hub. And the problem only shows itself with all 5 plugged in.

I have considered it being a faulty hub but it never gave any problems with the old mobo.

All the higher power drawing USB peripherals should really be plugged into the USB powered hub... Does the scanner have its own seperate PSU? What type of external hard drive is it, laptop size or full size?

All but the mouse have their own power supply.

Plugged directly into the back of the PC:

The scanner
The mouse
The USB Drive is an 80Gb Maxtor
The USB Hub (powered)


Into the USB Hub are:

Digicam
Printer
