qmi_wwan: set DTR for modems in forced USB2 mode 2018-09-18T02:23:27+00:00 Bjørn Mork bjorn@mork.no 2018-09-17T20:00:24+00:00 922005c7f50e7f4b2a6dbc182e9c575b4f92396b Recent firmware revisions have added the ability to force these modems to USB2 mode, hiding their SuperSpeed capabilities from the host. The driver has been using the SuperSpeed capability, as shown by the bcdUSB field of the device descriptor, to detect the need to enable the DTR quirk. This method fails when the modems are forced to USB2 mode by the modem firmware. Fix by unconditionally enabling the DTR quirk for the affected device IDs.
