Bug#810919: libsane: libusb_bulk_write returns "Resource temporarily unavailable"

[Steve Graham]

I totally agree with Adrian. My patch was just a workaround, but I thought it was worth documenting, 
because I did an internet search when I first experienced the problem, and other people with 
different scanners were reporting similar symptoms.

I haven't investigated further, but it did occur to me that there might be a bug in libusb, with the 
call completing before the device acknowledges a successful write. (I don't actually know how libusb 
works though.)
