From ffa5f7a3bf28c1306eef85d4056539c2d4b8eb09 Mon Sep 17 00:00:00 2001 From: Davide Tronchin Date: Thu, 22 Jun 2023 11:29:21 +0200 Subject: [PATCH] USB: serial: option: add LARA-R6 01B PIDs The new LARA-R6 product variant identified by the "01B" string can be configured (by AT interface) in three different USB modes: * Default mode (Vendor ID: 0x1546 Product ID: 0x1311) with 4 serial interfaces * RmNet mode (Vendor ID: 0x1546 Product ID: 0x1312) with 4 serial interfaces and 1 RmNet virtual network interface * CDC-ECM mode (Vendor ID: 0x1546 Product ID: 0x1313) with 4 serial interface and 1 CDC-ECM virtual network interface The first 4 interfaces of all the 3 USB configurations (default, RmNet, CDC-ECM) are the same. In default mode LARA-R6 01B exposes the following interfaces: If 0: Diagnostic If 1: AT parser If 2: AT parser If 3: AT parser/alternative functions In RmNet mode LARA-R6 01B exposes the following interfaces: If 0: Diagnostic If 1: AT parser If 2: AT parser If 3: AT parser/alternative functions If 4: RMNET interface In CDC-ECM mode LARA-R6 01B exposes the following interfaces: If 0: Diagnostic If 1: AT parser If 2: AT parser If 3: AT parser/alternative functions If 4: CDC-ECM interface Signed-off-by: Davide Tronchin Link: https://lore.kernel.org/r/20230622092921.12651-1-davide.tronchin.94@gmail.com Cc: stable@vger.kernel.org Signed-off-by: Johan Hovold --- drivers/usb/serial/option.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/drivers/usb/serial/option.c b/drivers/usb/serial/option.c index 644a55447fd7..cf53448e0384 100644 --- a/drivers/usb/serial/option.c +++ b/drivers/usb/serial/option.c @@ -1147,6 +1147,10 @@ static const struct usb_device_id option_ids[] = { { USB_DEVICE(QUALCOMM_VENDOR_ID, 0x90fa), .driver_info = RSVD(3) }, /* u-blox products */ + { USB_DEVICE(UBLOX_VENDOR_ID, 0x1311) }, /* u-blox LARA-R6 01B */ + { USB_DEVICE(UBLOX_VENDOR_ID, 0x1312), /* u-blox LARA-R6 01B (RMNET) */ + .driver_info = RSVD(4) }, + { USB_DEVICE_INTERFACE_CLASS(UBLOX_VENDOR_ID, 0x1313, 0xff) }, /* u-blox LARA-R6 01B (ECM) */ { USB_DEVICE(UBLOX_VENDOR_ID, 0x1341) }, /* u-blox LARA-L6 */ { USB_DEVICE(UBLOX_VENDOR_ID, 0x1342), /* u-blox LARA-L6 (RMNET) */ .driver_info = RSVD(4) },
