[sane-devel] Bugfix in Epson USB config

[Karl Heinz Kremer]

The user has to enable USB before scanners are recognized. With 
libusb, we can probably change this now. 

I disabled the probing vor USB scanners when other scanners were 
hanging the backend when they received unknown commands. With libusb,
this is no longer an issue, because the backend knowns which 
scanners (via the product and vendor ID) are supported.
