"I have a T2892 with a AU31 mobo. I recently bought a Lexmark X4250 printer. All was well during the install in windows. Upon reboot the computer would hang. Specifically, it would stop the boot process at the "e"splash screen. No POST beep and I cannot enter the BIOS.
If I unplug the USB cable and restart the computer the system will boot fine. I can plug the printer cable back in and it works. Just cannot startup with it plugged in.
I have tried three different cables and also tried my Canon Pixma iP3000 and the same problem.
I have already RMA'd the board twice because of this problem. eMachines says nothing is wrong both times.
BTW. I have a logitech mouse plugged in via USB and it works fine.
I even tried a complete restore via the disk and installed the printer per the manufacturers documentation. The same result. The computer would hang a the "e"splash screen and I could not get into the BIOS. Removal of the USB cable and the computer will boot. I did not find anything in the Device Manager relating to a bad driver issue. I have also uninstalled and reinstalled the drivers.
The Lexmark website is no help either. A google search did not reveal anything.
Any advice. I am comtemplating buying a new mobo. ASUS A7N8x-VM400 or MSI K7N2GM2-LSR. I would like to avoid having to do so."
Thanks in advance,
