[sane-devel] Problem with developing a new backend for Plustek OpticPro ST28

[Yury Tarasievich]

You are right, there are couple of registers in 
Wolfson DACs, accessed via some sort of specific 
serial interface. The frontend -- as the Genesys 
GL* datasheets understand the word. Never mind.

My scanner is indeed ST28 with USB IDs 0x7B3 
0x802. So yours would be, too.
Your hardware list fits perfectly what I saw in 
mine and what I was told by manufacturer.
