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 :)

problem with lastest u3g in RELENG_8

Hi,

I've got some troubles with the lastest revision of u3g in 8-STABLE.
Looks like it does not eject the fake cd device anymore :
That works fine with a kernel from 01/15/2010 (so i guess the culprit
is the latest version of u3g in stable : 01/17/2010)

The key is a ZTE MF633R
