[sane-devel] any sniff volunteers unsupported Canon scanners: 4200F, 5200F, 9900F, 9950F

Seems the LiDE series all uses Genesys Logic chips and/or Philips CP2155BE front-end. But some of the CanonScan series are still apparently unknown, and it would be fantastci if one or more of those used an existing protocol. Is there anyone who would be able to sniff a Windows USB log of the following scanners: * CanoScan 4200F * CanoScan 5200F * CanoScan 9900F * CanoScan 9950F Alternatively, opening up the scanner and listing all the chip information :-) But a sniff will be enough to get quite a bit of information. I see there appears to be a driver on Sourceforge, but I have no knowledge of what it can do: http://sourceforge.net/projects/cs5200drv/ You posted this nearly a year ago, are you still working on it? I have CanoScan 9950F and I can do a sniff for you if you still want one. Hi Rob, No, sorry, I am not involved in this anymore, I was trying to find devices that use a known pixma protocol, but that is not the case for the above scanners. You'll need to check the mailing list archives for separate threads on these scanners, if there are any, or start your own with USB sniffing. Genesys backend development is very lively, so if your scanner has such a chip, it is likely you will be roped in to help with support pretty quickly.

Could you spare some advice on programming the caret movement for the double-coil stepper motor controlled from GL84* (GL841, actually)? E.g., I can't figure out how the movement tables are formed (looking at the source and datasheet), and I'd really like to have safe movement cycle working (I nearly busted the motor in my Plustek ST28). -Yury On 03/03/2011 09:46 PM, stef wrote: Le Thursday 03 March 2011 16:24:34 Yury Tarasievich, vous avez ?crit : Would that somehow affect the support of other GL84* scanners? ... you are right.

[sane-devel] backend in progress: canon i-sensys mf4570dn, 'mfnp' protocol
hello Chris,
sorry for the delay, but I am quite overloaded with work $DAYJOB, and am
working on porting some other program stack to MacOS.

there is no backend that autodetects the device when on usb or ethernet,
none that is supposed to support it according to its description, and
the characteristic sequence of the protocol ('MFNP') i recorded from the
windows drivers is not found in the backend sources.
I developed the code using an MP970 that died. I am now using an MP980.
But the code works on a lot of devices using an ethernet or even
wireless connection. Again, does the device work over USB?
it does have usb, and is supposed to scan over usb as well, but i didn't
dig too deep there because i'd use in on ip in practice. also, sniffing
usb is a bit trickier than sniffing ethernet, and i'd need another
virtual machine environment to do it.
Please post the output of sane-find-scanner with the scanner attached
through USB. What chip is detected? Once we know if one of the existing
backends can be made to work over USB, I can have look at integrating
the MFNP stuff (which looks like USB over TCP!) in that backend. The
mfnp looks similar to BJBP, except for the last few packets, but that
may be an extension to read the buttons.
I had a quick look at the scanner protocol traces embedded in the TCP
packets, but they don't look faniliar to me, so this may not be a
scanner supported by the pixma backend (Nicolas, could you please have a
look if this looks like something familiar to you, as usual the USB data
starts at byte 16 after the USB over TCP header)?
Not that I know of. Does python allow for an easy wrapping of
C-libraries?
basically it does, and i've seen it has been attempted once, but there
is no further information than [1]. i've seen there is a network
backend as well; implementing that interface would probably be easier
and more portable.
[1] http://mail.python.org/pipermail/python-list/2006-March/977748.html
This does not look a very attractive route for integration in Sane to
me. Lets first see if sane-find-scanner recognizes the scanner when
attached over USB. It is quite likely that a well-known chipset is used
that is already supported by one of the existing backends. If so, and
the backend is patched to work with your scanner, we can look at USB
over TCP.
