HI,
As i knew, Avision, Silitek(HP OEMs), Primax , most use
genesys logic's usb chip and some scanlogic.
My Visioneer 8600 usb SANE, have code about genesys logic
about CONTROL modification on scanner.c
please visit http://www.littlecms.com/iphoto/otlinux.htm
And maybe have a discussion about merge ioctl part.
