I have a USB Visioneer Scanner that I would like to get working on Linux. So
far I have managed to:
1. Create snoop logs under windows
2. Execute those logs with libusb on linux
3. Determine the commands:
- to turn the Lamp On or Off
- to determine if a button on the scanner was pushed.
4. I am saving the output of usb_bulk_write to files
So far I am only scanning a B&W 9 pixel x 9 pixle area ...I am expexting an
81 byte file but I am getting much more than that.
Can some one help me take this raw output and convert in into an image file
I can view ?
Here is a listing of all the output files

Hello,
yes there is such a feature in linux kernel. You'll have to recompile
your
kernel with the following option (from kernel's configuration help):
CONFIG_USB_MON:
If you say Y here, a component which captures the USB traffic
between peripheral-specific drivers and HC drivers will be built.
For more information, see <file:Documentation/usb/usbmon.txt>.
This is somewhat experimental at this time, but it should be safe.
If unsure, say Y.
Symbol: USB_MON [=y]
Prompt: USB Monitor
Defined at drivers/usb/mon/Kconfig:5
Depends on: USB
Location:
-> Device Drivers
-> USB support
-> Support for Host-side USB (USB [=m])
Regards,
Stef
