The same twain driver handle these scanners:
Same family as KV-SS25, KV-SS50, KV-SS55, KV-SS50EX, KV-SS55EX, KV-SS850, KV-SS855.
Another driver handle the KV-S2055L, KV-S2055W.
However all these scanner show similarities.
/*--------------------------------------------------------------------------*/
SCSI commands supported by the KV-SS25:
TEST UNIT READY:

a return after a short read is:

The TWAIN driver always reads 0x8000 bytes at the time, except for
the last packet where it read the size left plus 2 more bytes (and
thus generating a check condition).
5: page side
