I don't see anything obviously wrong in these logs. Perhaps the device simply isn't cdc-compliant (some bits of the vendor driver certainly indicates that) despite what the vendor claims. Are you using the vendor driver or a generic cdc-acm driver on Windows? I don't have time to look into this in a few days, but would you be able to test patches that I send you? Possibly some diagnostic patches to determine if cdc-acm can be used, and if not, a dedicated usb serial driver? If so, you could compile your own mainline (or stable 3.16) kernel in the mean time so you have something to test the patches with.
