You reserve interface 6 below which doesn't even exist in the above configuration. Can you say something more about what the individual interfaces are used for, for example, as was done here: https://lore.kernel.org/all/TYZPR06MB4270D3394B8E3E0301738F6B86D09@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/ > Signed-off-by: Yonglin Tan <yonglin.tan@xxxxxxxxxxx> > --- > drivers/usb/serial/option.c | 2 ++ > 1 file changed, 2 insertions(+) > mode change 100644 => 100755 drivers/usb/serial/option.c > > diff --git a/drivers/usb/serial/option.c b/drivers/usb/serial/option.c > old mode 100644 > new mode 100755 > index ed1e50d..05fc322 > --- a/drivers/usb/serial/option.c > +++ b/drivers/usb/serial/option.c > @@ -1147,6 +1147,8 @@ static const struct usb_device_id option_ids[] = { > .driver_info = ZLP }, > { USB_DEVICE_AND_INTERFACE_INFO(QUECTEL_VENDOR_ID, QUECTEL_PRODUCT_EC200S_CN, 0xff, 0, 0) }, > { USB_DEVICE_AND_INTERFACE_INFO(QUECTEL_VENDOR_ID, QUECTEL_PRODUCT_EC200T, 0xff, 0, 0) }, > + { USB_DEVICE_INTERFACE_CLASS(QUECTEL_VENDOR_ID, 0x030a, 0xff), > + .driver_info = RSVD(6) | ZLP }, /* EM05-G */ As mentioned above RSVD(6) looks wrong here. Please move the comment to the first line of the entry, and move the entry to the other Quectel entries using numerical PIDs (i.e. before EM160R-GL). > { USB_DEVICE(CMOTECH_VENDOR_ID, CMOTECH_PRODUCT_6001) }, > { USB_DEVICE(CMOTECH_VENDOR_ID, CMOTECH_PRODUCT_CMU_300) }, Johan
