I've tested the snapscan backend directly, and thru net/saned, and
both fails 'scanimage -T'. Directly, running as root gives this
result:

scanimage: scanning image of size 2540x3429 pixels at 24 bits/pixel
scanimage: acquiring RGB frame, 8 bits/sample
scanimage: reading one scanline, 7620 bytes... PASS
scanimage: reading one byte... FAIL No data
scanimage: stepped read, 2 bytes... FAIL No data
scanimage: stepped read, 4 bytes... FAIL No data
scanimage: stepped read, 8 bytes... FAIL No data
scanimage: stepped read, 16 bytes... FAIL No data
scanimage: stepped read, 32 bytes... FAIL No data
scanimage: stepped read, 64 bytes... FAIL No data

scanimage: stepped read, 2047 bytes... FAIL No data
scanimage: stepped read, 1023 bytes... FAIL No data
scanimage: stepped read, 511 bytes... FAIL No data
scanimage: stepped read, 255 bytes... FAIL No data
scanimage: stepped read, 127 bytes... FAIL No data
scanimage: stepped read, 63 bytes... FAIL No data
scanimage: stepped read, 31 bytes... FAIL No data
scanimage: stepped read, 15 bytes... FAIL No data
scanimage: stepped read, 7 bytes... FAIL No data
scanimage: stepped read, 3 bytes... FAIL No data

The scanner then seems to lock up. When running as a normal user thru
the net/saned backend, this result follows:

scanimage: scanning image of size 2540x3429 pixels at 24 bits/pixel
scanimage: acquiring RGB frame, 8 bits/sample
scanimage: reading one scanline, 7620 bytes... PASS
scanimage: reading one byte... PASS
scanimage: stepped read, 2 bytes... PASS
scanimage: stepped read, 4 bytes... PASS
scanimage: stepped read, 8 bytes... PASS
scanimage: stepped read, 16 bytes... PASS
scanimage: stepped read, 32 bytes... PASS
scanimage: stepped read, 64 bytes... PASS
scanimage: stepped read, 128 bytes... PASS
scanimage: stepped read, 256 bytes... PASS
scanimage: stepped read, 512 bytes... PASS
scanimage: stepped read, 1024 bytes... FAIL No data
scanimage: stepped read, 2048 bytes... FAIL No data
scanimage: stepped read, 4096 bytes... FAIL No data
scanimage: stepped read, 8192 bytes... FAIL No data
scanimage: stepped read, 8191 bytes... FAIL No data
scanimage: stepped read, 4095 bytes... FAIL No data
scanimage: stepped read, 2047 bytes... FAIL No data
scanimage: stepped read, 1023 bytes... FAIL No data
scanimage: stepped read, 511 bytes... FAIL No data
scanimage: stepped read, 255 bytes... FAIL No data
scanimage: stepped read, 127 bytes... FAIL No data
scanimage: stepped read, 63 bytes... FAIL No data
scanimage: stepped read, 31 bytes... FAIL No data
scanimage: stepped read, 15 bytes... FAIL No data
scanimage: stepped read, 7 bytes... FAIL No data
scanimage: stepped read, 3 bytes... FAIL No data

The scanner does not lock up in this case. Any one know how to fix
this?
