[sane-devel] Sane backend for an intraoral X ray camera

[m. allan noah]

I'm not familiar with the pint interface, but I'd be surprised if it
works generically with any twain scanner. How would the windows twain
driver run on BSD without some kind of OS emulator?

I think you have far more work to do than you realize.The first step
would be to get some usb logs of the scanner in action using wireshark
on windows. Someone here may recognize the image format or protocol.
