It's a UMAX Astra 2100U, so a USB scanner. From what I could find, this dates back to 2001. While this is a 10-year old device, if a 600x1200 dpi scan is what you need, it would be nice to have a working driver.
But according to UMAX, the 2100U scanner is supported only under Windows 98/98SE/ME/2000/XP and Mac OS 8.0 to 9.1. Confirming this, the UMAX support download page doesn't have drivers available for Windows Vista or Windows 7. Mac users are also out of luck, as MacOSX drivers aren't available, either.
But Windows and Mac support may not be all that great, anyway, even on the versions officially supported by UMAX. This review from 2001 warns about driver compatibility:
This tempting scanner can give great scans, unfortunately the software required to run it crashes both Macs on which I tried it, and it rewrote system files on the Win2000 PC I on which I tried (unsuccessfully) installing it.
It is incompatible with a Mac running iTunes 1.1 software. UMAX says they are working on this as of March 2001. Good luck!
It also made a 350MHz iMac completely unstable and unbootable. It took over an hour for of one of the most kind-hearted Mac specialists in San Diego to get it running again.
Another reader in Chicago wrote ME trying to get my help in getting her system to run. UMAX couldn't get it to go. That's too bad, because I gave up myself. Hopefully UMAX will take back her scanner.
Maybe that's why this scanner was in our storage area, with a note taped to it reading "No longer works - cannot find working driver."
Out of pure curiosity, I plugged the scanner into my Linux laptop. A few clicks in "System - Administration - Add/Remove Software" and I had installed Sane and the plugins for Gimp. So about 2 or 3 minutes.
Sure enough, the scanner works! I scanned a few test images, whatever I had around the office, and loaded them directly into Gimp. Works great! Another example where Linux support is ahead of the competition.
