[PATCH v3] USB: serial: option: add id for Motorola Solutions TETRA PEI

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add Motorola Device ID and blacklist entry to the driver usb/serial/option

The device responds with URB status: Broken pipe (-EPIPE) (-32)
to URB setup requests for setting dtr/rts.

So blacklisting to avoid the usb_wwan_send_setup in usb_wwan_dtr_rts of usb_wwan.
Tested now to work with miniterm.py and minicom without errors.
