I have the same problem reported by Jonas. Telit flashing procedure does not work with the cdc-acm driver. Moreover, the device 0x058b/0x0041 is in itself a flashing device, so /* Infineon Flashloader driver */ section of usb-serial-simple seems a good place for it. Since the procedure is working properly with only bulk endpoints I suspect that on the firmware side the definition of the device is not correct.
