Thanks for the log file. Just one thought after quick reading - first
line passed ok (scanimage: reading one scanline, 2550 bytes...), after
that scanimage tries to read 1, 2, 4, 8, 16 ... 4096, 4095 ... 7, 3
bytes which were failed. This is 'test mode' of scanimage (-T command
line switch). Could you please try without the switch? Scanning with
the same parameters but using different frontend would also be
helpful...

In the mean time, I will try to analyze why the backend has
difficulties with scanimage 'test mode'
