I too, have been ticked off by this one. It is affecting my ability to do business. I even tried my HP ScanJet 6390C usb-scanner, I still have. It to is screwed. I borrowed a friends UMAX 3400 usb-scanner too, yep borked! I was working for 15 days with my new Epson RX600. Printing still works JUST FINE, but scanning *IS HOSED*. I reverted... to the revision I had when I installed the scanner. No joy. Something else is bad. I also purged (all printing and scanning software) restarted the machine from COLD (printer/scanner) and computer. The re-installed, no joy. Maybe we should look at the packages, seems libusb was compiled on Feb 2, 2005. That is the right amount of time for it to get through incoming...etc Yep, Libusb-0.1-4 v1:0.1.9-2 is the culprit. Revert to the version in Sarge, by going to http://packages.debian.org/testing/libs/libusb-0.1-4 And downloading for your architecture. -- greg, greg@gregfolkert.net The technology that is Stronger, better, faster: Linux
