From your post I figure you do not use hibernate or suspend?
Anything else that behaves odd?
- if you plug in another usb device (flashdrive, mouse, usb hub, etc) you lose communication with the printer or if you have an usb mouse plugged in then plug in a printer the mouse stops working, etc....
Is it the same in all USB ports?
- yes 2.0 or 1.1
Any difference if you use or not use the printer?
- If you have an usb mouse plugged in and then plug in a usb flashdrive the mouse stops working
Much use - little use?
- heavy use in short bursts then maybe 20 - 24 hours repeat the process
Anything else I can give you please let me know. I googled this problem for several days before posting and am at a complete loss.
