The official LARA-R6 (00B) modem uses 0x908b PID. LARA-R6 00B does not implement a QMI interface on port 4, the reservation (RSVD(4)) has been added to meet other companies that implement QMI on that interface. LARA-R6 00B USB composition exposes the following interfaces: If 0: Diagnostic If 1: AT parser If 2: AT parser If 3: AT parser/alternative functions Signed-off-by: Davide Tronchin <davide.tronchin.94@xxxxxxxxx> Cc: stable@xxxxxxxxxxxxxxx Signed-off-by: Johan Hovold <johan@xxxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/usb/serial/option.c | 2 ++ 1 file changed, 2 insertions(+) --- a/drivers/usb/serial/option.c +++ b/drivers/usb/serial/option.c @@ -1126,6 +1126,8 @@ static const struct usb_device_id option /* u-blox products using Qualcomm vendor ID */ { USB_DEVICE(QUALCOMM_VENDOR_ID, UBLOX_PRODUCT_R410M), .driver_info = RSVD(1) | RSVD(3) }, + { USB_DEVICE(QUALCOMM_VENDOR_ID, 0x908b), /* u-blox LARA-R6 00B */ + .driver_info = RSVD(4) }, { USB_DEVICE(QUALCOMM_VENDOR_ID, 0x90fa), .driver_info = RSVD(3) }, /* Quectel products using Quectel vendor ID */ Patches currently in stable-queue which might be from davide.tronchin.94@xxxxxxxxx are queue-5.15/usb-serial-option-add-u-blox-lara-r6-00b-modem.patch queue-5.15/usb-serial-option-remove-old-lara-r6-pid.patch queue-5.15/usb-serial-option-add-u-blox-lara-l6-modem.patch
