[sane-devel] [PATCH] umax: disable gamma download for UC630

[Ondrej Zary]

UC630 does not support gamma download - it aborts the command:
[umax] sending 256 bytes of gamma data for color 1
[umax] send_gamma_data
[umax] using gamma download curve format type 2
[umax] check condition sense handler (scsi_fd = 3)
[umax] check condition sense: ILLEGAL REQUEST
[umax] -> illegal field in CDB
[umax] -> illegal parameter is in the data parameters sent during data out phase
[umax] -> error detected in byte 2

It does not cause any harm but disable it anyway.
