I managed to get hold of an old laptop with Windows XP on, and have installed the 7600i drivers (and included QuickScan application). This app will do preview scans (as well as 600, 1200, 2400, 3600 and 7200 dpi scans). Now, whch tools should i use to log the usb traffic? This[1] one? References: 1) http://benoit.papillault.free.fr/usbsnoop/ Hello, I'd recommend http://www.pcausa.com/Utilities/UsbSnoop/ . Regards, Stef Ok, usbsnoop log file here: http://ge.tt/5EMIzWD1/v/0 (zipped 6.6 MB, unzipped about 26.1 MB) Not sure how long it's gonna stay there (ok, the FAQ says 30 days). What I did: - after installing the filter, I selected Replug. Next I pressed the QuickScan button on the scanner (the only way to start the QuickScan application, AFAICT), which did a prescan. QuickScan settings are Negative Film, Preview enable and defaults for the rest. I'm not sure what resolution etc. the prescan is done with. Hope this helps. Hello, I have downloaded and decoded the log. I can confirm it is a genesys based device. However since the chip used can only do 2400 dpi max, I expect some hardware trick if this scanner can reach the 7200 hardware resolution. Another thing is that used SCANMOD is tagged 'RESERVED' in GL842 datasheet. So I expect it will be different from other supported scanners that don't use this SCANMOD So since it is no close enough to other devices I have, I cannot add support for this model without having the real hardware.

[sane-devel] Neat NM-1000

Someone previously tried to get it working, but ultimately could not determine which chipset it uses: http://lists.alioth.debian.org/pipermail/sane-devel/2011-June/028637.html The chipset is still not detected with the latest SANE backends (1.0.24). 'sane-find-scanner -v -v' reports: Couldn't determine the type of the USB chip (result from sane-backends 1.0.24) The e-mail linked above suggested using usbsnoop on Windows to capture a log, from which it might be possible to determine the chipset. I installed usbsnoop from http://sourceforge.net/projects/usbsnoop/, but it does not seem to be functional in Windows 7. Is there another USB sniffer that might capture the relevant information? Would it be possible to determine the chipset from taking it apart and examining the internals? There seem to be no accessible screws on the device, so I am not sure I can open it without breaking it (but am willing to do that as a last resort). Is reverse engineering the Windows or Mac drivers a possibility for determining the chipset? Maybe running them through 'strings' would be revealing? Thanks, Kentrell Hello, this scanner has been identified as a gl846 based scanner. See https://alioth.debian.org/tracker/?func=detailgroup_id=30186aid=312366atid=410369 . Regards, Stef
[sane-devel] Linux support for Scanjet 300 ?

After connecting it, dmesg shows it's there and sane-find-scanner shows ?(vendor=0x03f0, product=0x1d05, chip=GL848+?) at libusb:003:005, but scanimage -L says no scanners were identified. The sane-project page doesn't show it, and the seller doesn't mention Linux as supported (for any scanner, not even for the more expensive supported ones), but mentions Linux in the properties. So my question is, since 1.0.21 is old, is it supported in the newer versions? Or will it be soon ? Thanks. Hello, this scanner is not supported. Since it is a GL848 based scanner, it could be added to the genesys backend. Regards, Stef -- next part -- An HTML attachment was scrubbed...

[sane-devel] Testers needed (mx520 series)
Hi there, On your page i found you need testers for the mx520 series. I have a Canon pixma mx525 here, and it seems not to work with sane. I'm trying to use it with the network, maybe I should try an usb cable too. but just please tell me how to help you to get it to work (and you help me of course. :) So what can I do? - Martin

Understood. This scanner is already replaced with a newer model (the 8200) here in Norway at least. Where in the world are you located? There is one 7600i available at eBay: http://www.ebay.com/itm/Plustek-OpticFilm-7600i-SE-Film-Scanner-Slide-Film-Scanner-90days-warranty-/171211841146 But USD 229.- plus shipping is a bit much for me to cover by myself. Perhaps if a few more persons were interested in getting this scanner supported, we (the interested persons) could split the cost? Just a thought. -- Regards, Torfinn Ingolfsen
