That's not a good situation. Unless you know how the device works, you're
reduced to guessing... and your guesses will probably be wrong.

For the last line, if the device was standard you would put
US_SC_SCSI, US_PR_BULK, NULL, 0),
What you have above (US_PR_CBI together with US_FL_BULK32) makes no sense
at all. However, since the device isn't standard even this probably won't
work.

Actually the real error was this:
[17179772.196000] usb 1-1: can't restore configuration #128 (error=-32)
The later errors were results of this one.

Wrong. The configuration _is_ found. The error occurs in the call to
usb_control_msg.

Not unless you can find out how it's supposed to work. You might be able
to do this by tracing the USB packets sent by the Windows driver. Or you
might able to get the information from the manufacturer.
