Zesore,

Welcome to the Dell Community Forum (DCF).
Do other USB devices work on all of the 110 USB ports?

Yes there is a USB Mouse on the other USB Port. I changed this device to the other Port and plugged the CD Writer on this Port, but it doesn't run.

System:

Optiplex GX110
Service Tag: LVEWF
Windows XP with all Updates (except SP2) and newest drivers (Chipset, Video, Audio, NIC...)

CD Writer: PLEXTOR PlexWriter PX-S2410TU, USB 2.0

Wenn i plug the Writer to the USB Port, the PC freeze. The only thing i can do is unplug the Power Cable. No Error Message, no Warnings.

This CD Writer functioned on the PC a few Weeks, but not anymore. I think i make a new XP Installation on this PC if no one has a good tip.

Regards Simon

You havent given ANY model or version or OS information like Service Tag, WIN9X/ME/2000/XP.
Nor have you said what kind of USB drive this is.

Nor have you defined "doesnt work" or given any error messages or any other information.

It could be a problem with the power (to less power from USB1.1)? We only have USB Hubs without Power Connection, so i will install a new GX280, then i think the Problem will be solved.
