This should be controlled by the cdc-acm driver, not the usbserial driver. That driver should be auto-loaded for this device, but it looks like the descriptor is wrong, so it's not binding to it. Are you able to test a patch and rebuild the kernel to see if we can get this to work properly? thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
