Well, no-one else has stepped forward to say they are working on this device, so it looks like if I want a backend for it then... I'm it! :o)
I suspect it may share the same chipset as some other devices which people are working on (see below) so I might not have as much to do as I'd thought (hope springs eternal...). I've been in touch with the Visioneer technical department and not had any luck so far but have started an e-mail conversation with one of their technical bods (who seems quite interested) so one for the back burner. ;o) On Sun, 30 Nov 2003 13:15:15 +0100 "Jaeger, Gerhard" <gerh...@gjaeger.de> wrote: > I'm pretty shure, that the Visioneer 4400 does not contain a LM983x ASIC. > I checked some logs in spring this year, and there it turned out to be a > GeneSysLogic based device, at least containing a GL 640 bridge.

Now all I've got to find out is what ASIC means. :o) (an Epson site I've just Googled says it means "Application-Specific Integrated Circuit") The general opinion seems to be that the Visioneer Onetouch 4400 USB (V1T4400U for short) is also retailed as; - Visioneer Primascan Colorado 2600u - Primax Primascan Colorado 2600u - Memorex 6142u Anyone working on any of these? My output for /proc/bus/usb/devices and sane-find-scanner -v -v is identical to that mentioned on the unsupported scanner web page. Which also suggests that the USB Descriptor looks similar to the; - Genius Colorpage Vivid III (USB) and - Pacific Image Electronics (PIE) Primefilm 1800u I know that Alexander Feldman is working on the Primefilm 1800u (hi Alex, if you're reading this, I may be in touch real soon now :o) ) and someone said at the end of June this year that they were considering writing a backend for the Genius Colorpage. So they might be lines worth pursuing. There is some speculation about whether the device uses the E1, E3 or E5 chipset. Can anyone point me to a place where I can read up on what the significance of E1, E3 and E5 is? Are there any good places to read up on scanner hardware technology in general so I've got at least some idea what's going on? Is the next step to get hold of something called a USB snooper? (I've got some links but recommendations are welcome). I'd appreciate a pointer to some info on how this is used. Right, I've got a whole load of stuff off the SANE web site which I need to read and the SANE docs directory to dig around in. BRB! :o) Keith
