I wasn't really up to that unfortunately :( I had a look and I couldn't see it free anything, but I am not 100% sure=20 how the libusb stuff works internally. I note that the pdev does not=20 appear free'd but uninitialised. However I did notice that SANE has 1.0 API support and using that does=20 not trigger this problem.
