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 
how the libusb stuff works internally. I note that the pdev does not 
appear free'd but uninitialised.

However I did notice that SANE has 1.0 API support and using that does 
not trigger this problem.

Now to convince configure to pick it up by default :)
