Without this flag, the option driver binds to the MBIM interface and conflicts with the cdc_mbim driver, causing AT/MBIM communication failures. This matches the handling of other Rolling Wireless MBIM devices. This patch adds the missing RSVD(5) quirk for Rolling RW135R-GL (33f8:1003) to prevent the option driver from probing the MBIM control interface, which avoids conflicts with cdc_mbim and fixes communication failures. This aligns with the configuration used by all other Rolling Wireless MBIM = modems. v4: - Fixes tag corrected - Device table entry formatting aligned with existing pattern Tested successfully on multiple interface configurations: - mbim + diag + AT + pipe - mbim + diag + AT + ADB + pipe - mbim + pipe Fixes: 01e8d0f74222 ("usb: serial: add support for Rolling Wireless RW135R-= GL (33f8:1003)") Signed-off-by: Wanquan Zhong --- drivers/usb/serial/option.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/usb/serial/option.c b/drivers/usb/serial/option.c index c71461893d20..dfec7467b36c 100644 --- a/drivers/usb/serial/option.c +++ b/drivers/usb/serial/option.c @@ -2466,7 +2466,8 @@ static const struct usb_device_id option_ids[] =3D { { USB_DEVICE_INTERFACE_CLASS(0x33f8, 0x0302, 0xff) }, /* Rolling RW101R= -GL (laptop MBIM) */ { USB_DEVICE_INTERFACE_CLASS(0x33f8, 0x0802, 0xff), /* Rolling RW350-GL= (laptop MBIM) */ .driver_info =3D RSVD(5) }, - { USB_DEVICE_INTERFACE_CLASS(0x33f8, 0x1003, 0xff) }, /* Rolling RW135R= -GL (laptop MBIM) */ + { USB_DEVICE_INTERFACE_CLASS(0x33f8, 0x1003, 0xff), /* Rolling RW135R-G= L (laptop MBIM) */ + .driver_info =3D RSVD(5) }, { USB_DEVICE_AND_INTERFACE_INFO(0x3731, 0x0100, 0xff, 0xff, 0x30) }, /* N= etPrisma LCUK54-WWD for Global */ { USB_DEVICE_AND_INTERFACE_INFO(0x3731, 0x0100, 0xff, 0x00, 0x40) }, { USB_DEVICE_AND_INTERFACE_INFO(0x3731, 0x0100, 0xff, 0xff, 0x40) }, --=20 2.43.0
