Help!! USB port problem.

onejontwo

Help!! My printer has just packed up (epson stylus DX 4450) I can get it to print after scanning an item so I know the printer is able to print, but in device manager under Universal Bus Controllers it shows 3 yellow exclamation marks for:-
SIS 7001 PCI to USB OPEN HOST CONTROLLER
SIS 7001 PCI to USB OPEN HOST CONTROLLER
SIS PCI to USB ENHANCED HOST CONTROLLER
As the printer is connected by USB is this where the fault lies and what do I do to fix it?
I've tried the trouble shooting but I'm having no luck.
Thanks in anticipation.

The problem is at the PC end, not the printer.

In device manager you could open the settings for each of the entries click on the driver tab, and either update or rollback the driver - that may do the trick.

If that doesn't work - do you have a system disc with drivers on it for the machine ? - you may need to re-install the USB drivers. If you don't have a disc you may be able to download them from the manufacturers website.

Or even try uninstalling those drivers and rebooting .

How could I just lose those drivers if that is the fault?

I've tried un installing the drivers and re booting also rolling back the drivers but still showing an exclamation mark. Also each exclamation mark shows this when clicking on it :-
A driver (service) for this device has been disabled. An alternate driver may be providing this functionality. (Code 32)
and
The drivers for this device are not installed. (Code 28)


Would this be due to a virus or windows update or something else?

Thanks , tried it but it seems to be just maintenance stuff. I really need to renew/ install the disabled drivers somehow. I've tried system restore and reinstalling from the supplied disc I got with the PC, but it seems hopeless.

Any computer savvy techies out there?? I'm sure it's simple it's just knowing the right buttons to press.
Please don't make me resort to PC World!!
