v2: reformatted Patch, first version was declined by GK-H's Bot
Thanks for the help, Johan!
To an URB setup request from the host
bmRequestType: 0x21
bRequest: 34
wValue: 0x0003
wIndex: 0 (0x0000)
wLength: 0
the device responds with
URB status: Broken pipe (-EPIPE) (-32)
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.
