It should be possible...but this does not use libusb, it is a patch to the scanner module. There is alot of code there I do not understand. I am trying to follow the instructions in backend-writing.txt "write a stand-alone scanning program first". By starting from scratch I am learning alot.

Yes, Input to this perl script is the output from a windows usb snoop log. This script generates c code using libusb that compiles and executes the same USB commands that were captured in from the snoop. > On the other hand, if it has such grave bugs it may be better not to > link to it. Just like all programs, it will get better as time goes on. It has been the best tool I have found that gives me a jumpstart to understanding libusb. Hopefully in the future this will get included in the libusb project tree. > I guess OUT OUT should be usb_bulk_write and OUT IN should be > usb_bulk_read > > Yes.

I had a Canoscan 3000f, but it wasn't supported, so I bought a new scanner, a Canoscan Lide 60; I choice this model because I saw that it is supported (it is listed GOOD, only buttons on the scanner haven't to work), but it doesn't work. I have installed also the last CVS backends, but nothing. The device is correctly linked to my PC, but drivers don't configure it right, I also have installed the last libusb, but nothing. Is there someone who can help me? I can't go to the shop where I bought the scanner and ask if they can change it for another model! Bye and sorry for my language errors, I hope that you understand what is my problem.
