Hi,
I've made usb-storage recognise the Microtek X6 scanner. From a trace
under Windows98 we know that it uses a protocol which sends raw SCSI
commands over one pipe and reads the result from another pipe. It uses a
third pipe to read results from READ IMAGE in larger chunks. For now I
used transparent SCSI over bulk transport. This gives strange results.
To me it looks like the scanner is putting out excessive bogus data as a
result of TEST_UNIT_READY. But I would like to ask for help.
TIA
