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> --- V4 -> V5: kept PID 0x90fa to maintain the support for other products which use VID:PID 0x05c6:0x90fa. Remove interface 4 from blacklist for LARA-L6 default mode since it is not needed. V3 -> V4: as requested, the patch has been split to 3 sub-patches. Fix comment format. V2 -> V3: added this section to tracking changes with previous versions. Added some explanations about the RSVD(4) in the description session. Added reservation to port 4 of VID:PID 0x05C6:0x908B to meet other companies QMI net interface implementation. V1 -> V2: define UBLOX_PRODUCT_LARA_R6 0x908b has been deleted together with the previosly provided definition of USB_DEVICE since the PID is used by another vendor. The LARA-L6 patch part is the same of the previosly provided one. drivers/usb/serial/option.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/usb/serial/option.c b/drivers/usb/serial/option.c index b93285b5175b..011b9a3b7571 100644 --- a/drivers/usb/serial/option.c +++ b/drivers/usb/serial/option.c @@ -1125,6 +1125,8 @@ static const struct usb_device_id option_ids[] = { .driver_info = RSVD(1) | RSVD(3) }, { USB_DEVICE(QUALCOMM_VENDOR_ID, 0x90fa), .driver_info = RSVD(3) }, + { USB_DEVICE(QUALCOMM_VENDOR_ID, 0x908b), /* u-blox LARA-R6 00B */ + .driver_info = RSVD(4) }, /* Quectel products using Quectel vendor ID */ { USB_DEVICE_AND_INTERFACE_INFO(QUECTEL_VENDOR_ID, QUECTEL_PRODUCT_EC21, 0xff, 0xff, 0xff), .driver_info = NUMEP2 }, -- 2.34.1
