Beside this patch there are the following to-do's left for follow-up patches: * In principle, the esd CAN-USB/3 supports Transmitter Delay Compensation (TDC), but currently only the automatic TDC mode is supported by this driver. An implementation for manual TDC configuration will follow. * Rework the code to no longer switch directly on the USB product IDs to handle different device setting for each supported USB device. Instead use the driver_info member within struct usb_device_id to hold / point to specific properties for each supported device. * Try to switch from synchronous send usb_bulk_msg() to asynchronous communication by means of usb_submit_urb() where it is feasible.
