Dear developers

I've got an obscure scanner which I really need to get working and I'm prepared to get my hands dirty but I can't find much documentation.

Any tips/pointers would be very helpful.

It's a Vidar Diagnostic Pro digitizer -- used in radiology to scan X-rays from old radiographic film. As you can imagine, it's quite a niche product.

Output:

# dmesg
[ 179.813929] usb 1-2: USB disconnect, device number 6
[ 181.783329] usb 1-2: new high-speed USB device number 7 using xhci_hcd
[ 181.933595] usb 1-2: New USB device found, idVendor=0c58, idProduct=0100
[ 181.933599] usb 1-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3

# Your USB scanner was (probably) detected. It may or may not be supported by
# SANE. Try scanimage -L and read the backend's manpage.

# Not checking for parallel port scanners.

# Most Scanners connected to the parallel port or other proprietary ports
# can't be detected by this program.

unfortunately it is not listed on # scanimage -L

If I make any progress (with or without help), I would like to submit my work back to the project. I have some experience in C and Python and am prepared to learn as needed.
The alternative is a very expensive proprietary closed source vendor solution with unreliable support and a poor security update record.

Best wishes

Make some scans with the scanner on windows, and capture the USB
packets with wireshark. Then put the wireshark logs up on the web for
others to look at, while you attempt to make sense of them too :)

Thanks Allan for your advice. I've finally managed to capture some logs.

I'm trying to make sense of them now using Wireshark. Any help/pointers would be much appreciated, as I'm pretty new to this.

I've uploaded them to here:
