I thought 3900 series scanners would share the same chipset class too. That's why I called my backend "hp3900". As far as I know, Realtek chipset is not compatible with GLxxx_HP. At least, the way in which each chipset is programmed is different. Also, ScanJet 4070 uses the same chipset as ScanJet 3970 so, i guess scanners included in 3900 series share some simmilar features but chipset is not one of them. > Memory seems to be consistent at what looks like 64mb (if I'm reading > it correctly) except the 3650c which looks like 32mb. > > If it's supported I guess no need to enable the backend (only genesys > is currently enabled) to play with it so I'll set it aside and put a > stickie on it. In fact, hp3900 backend was written to support ScanJet 3970.
