More usually, though it shows as "Epson Stylus CX5200" under unknown devices, with no question mark or exclamation point. I understand that when working properly it should be listed as an "Imaging Device".

Blake (42 messages posted) I have tried going to the NVIDIA drivers site, but I'm not sure WHAT driver I need for the thing, or how to install it. I tried uninstalling and reinstalling something called "NVIDIA Device Drivers", using Windows' Add/Remove Hardware, then my NVIDIA original CD. If I can provide any more specs, let me know what you need. Thanks in advance for any help you might be able to give me, triplate!

Blake (42 messages posted) I have uninstalled and reinstalled the Epson drivers several times with no luck. Epson tech support tells me the printer and its drivers are 100% XP compatible. I have even downloaded a driver from the website, the same thing happens. That is why I'm guessing this might be a conflict with the PCI Bus controller...I did manage to make a small step last night. I downloaded the 2.45, newest Nvidia "unified" driver package and installed it in Safe Mode. That seemed to make the Nvidia PCI controller show up as working, and using resources. (Before it would say "This device is not using any resources because there is a problem with it." But on the main properties page, it still says there is no driver installed for the device, and my scanner isn't working yet......I'm getting bummed!
