DOH! I am glad you picked that up. I would love to look for that firmware, but I don't know what tool(s) to use to do that. I assume some soft of binary diffing tool. If anybody knows of a good free Win2000 binary diffing tool, let me know. Otherwise I will try googling it. Betrik Sikken was nice enough to extract what is being uploaded by hand (I assume from URB 1-53) and send it to me. I am attaching it.

The problem I am having is that I can scan about 10 images or so and then the scanner needs to be unpluged from usb and pluged back in. The scanner just stops working after about 10 scans or so. I reset the power on the scanner also when doing this. The errors I get from xsane are these: Error during read: Error during device I/O Failed to open `(null)': Bad address Failed to start scanner: End of file reached I am using sane-backends 1.0.18-r2 xsane 0.991 libusb 0.1.12 kernel 2.6.16-gentoo-r9 cpu amd64 (x86_64) distro Gentoo usb bus uhci_hcd The command line tool scanimage gives me all the same issues that xsane does. Let me know what I should do to debug this issue. I know c but have not dived into the code yet. Any debugging docs for sane backends. Is this a libusb issue? I guess I need to know where to point the finger. Jeremiah
