Hi all ! About the OpticFilm 7200 (see my previous message), I have some more info... First, let me just paste the related content of my /proc/bus/usb/devices :
--------------------------------/proc/bus/usb/devices-------------------------- T: Bus=04 Lev=01 Prnt=01 Port=02 Cnt=01 Dev#= 2 Spd=480 MxCh= 0 D: Ver= 2.00 Cls=ff(vend.)

MxPS= 1 Ivl=16ms -------------------------------------------------------------------------------------- Apart from the speed value of 480, the MaxPacketSize of 512 and the interval of 16ms in the last of the above lines, this is very much the same as on the webpage at http://www.sane-project.org/unsupported/plustek-opticfilm-7200.html Let's continue with the result of a sane-find-scanner -v -v : ---------------------------sane-find-scanner -v -v------------------------------ This is sane-find-scanner from sane-backends 1.0.17 trying libusb: <device descriptor of 0x07b3/0x0807 at 004:002> bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 255 bDeviceSubClass 255 bDeviceProtocol 255 bMaxPacketSize0 64 idVendor 0x07B3 idProduct 0x0807 bcdDevice 3.06 iManufacturer 10 ((null)) iProduct 11 ((null)) iSerialNumber 12 ((null)) bNumConfigurations 1 <configuration 0> bLength 9 bDescriptorType 2 wTotalLength 39 bNumInterfaces 1 bConfigurationValue 1 iConfiguration 0 () bmAttributes 192 (Self-powered) MaxPower 10 mA <interface 0> <altsetting 0> bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 3 bInterfaceClass 255 bInterfaceSubClass 255 bInterfaceProtocol 255 iInterface 0 () <endpoint 0> bLength 7 bDescriptorType 5 bEndpointAddress 0x81 (in 0x01) bmAttributes 2 (bulk) wMaxPacketSize 512 bInterval 0 ms bRefresh 0 bSynchAddress 0 <endpoint 1> bLength 7 bDescriptorType 5 bEndpointAddress 0x02 (out 0x02) bmAttributes 2 (bulk) wMaxPacketSize 512 bInterval 0 ms bRefresh 0 bSynchAddress 0 <endpoint 2> bLength 7 bDescriptorType 5 bEndpointAddress 0x83 (in 0x03) bmAttributes 3 (interrupt) wMaxPacketSize 1 bInterval 8 ms bRefresh 0 bSynchAddress 0 <trying to find out which USB chip is used> checking for GT-6801 ... this is not a GT-6801 (bcdUSB = 0x200) checking for GT-6816 ... this is not a GT-6816 (bDeviceClass = 255, bInterfaceClass = 255) checking for GT-8911 ... this is not a GT-8911 (check 1, bDeviceClass = 255, bInterfaceClass = 255) checking for MA-1017 ... this is not a MA-1017 (bDeviceClass = 255, bInterfaceClass = 255) checking for MA-1015 ... this is not a MA-1015 (bcdUSB = 0x200) checking for MA-1509 ... this is not a MA-1509 (bcdUSB = 0x200) checking for LM983[1,2,3] ... this is not a LM983x (bcdUSB = 0x200) checking for GL646 ... this is not a GL646 (bDeviceClass = 255, bInterfaceClass = 255) checking for GL646_HP ... this is not a GL646_HP (bcdUSB = 0x200) checking for GL660+GL646 ... this is not a GL660+GL646 (bDeviceClass = 255, bInterfaceClass = 255) checking for GL841 ...

On the sane-project webpage listing the unsupported devices, it is said "probably a GL841", based upon a trial by sane-find-scanner, probably. To make sure, the first thing I did after unpacking my brand new scanner was to open it (carefully!) and check for the chipset used. And it IS a GL842, not 841. As trustworthy as my eyes can be. It's all for today, I'm starting to have a look at the genesys backend and go through the GL841 and GL842 datasheets to make out where exactly is the difference between them. JB P.S. Henning, I've just sent you the form reporting for an unsupported device with the above information...
