Using the option driver for just a debug port seems like overkill, but ok. Some form issues: - When updating a patch always include a patch revision number in the Subject prefix (e.g. "[PATCH v2] USB: serial: option: add ..."). - Include a short changelog below the "---" line so we know what changed since the previous version. - Try to follow the convention used by the subsystem for the Subject prefix (i.e. "USB: serial: option: add ..."). > --- And please keep the lsusb -v info here below the cut-off line when resending. > 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 54ca85cc920d..fda291e68e4b 100644 > --- a/drivers/usb/serial/option.c > +++ b/drivers/usb/serial/option.c > @@ -424,6 +424,7 @@ static void option_instat_callback(struct urb *urb); > #define CINTERION_PRODUCT_AHXX_2RMNET 0x0084 > #define CINTERION_PRODUCT_AHXX_AUDIO 0x0085 > #define CINTERION_PRODUCT_CLS8 0x00b0 > +#define CINTERION_PRODUCT_EXS82 0x006c Please keep the entries sorted by PID. > > /* Olivetti products */ > #define OLIVETTI_VENDOR_ID 0x0b3c > @@ -1908,6 +1909,7 @@ static const struct usb_device_id option_ids[] = { > { USB_DEVICE(SIEMENS_VENDOR_ID, CINTERION_PRODUCT_HC25_MDMNET) }, > { USB_DEVICE(SIEMENS_VENDOR_ID, CINTERION_PRODUCT_HC28_MDM) }, /* HC28 enumerates with Siemens or Cinterion VID depending on FW revision */ > { USB_DEVICE(SIEMENS_VENDOR_ID, CINTERION_PRODUCT_HC28_MDMNET) }, > + { USB_DEVICE_INTERFACE_CLASS(CINTERION_VENDOR_ID, CINTERION_PRODUCT_EXS82, 0xff) }, And keep these sorted alphabetically if possible (at least keep the CINTERION_VENDOR_ID entries together). > { USB_DEVICE(OLIVETTI_VENDOR_ID, OLIVETTI_PRODUCT_OLICARD100), > .driver_info = RSVD(4) }, > { USB_DEVICE(OLIVETTI_VENDOR_ID, OLIVETTI_PRODUCT_OLICARD120), Care to fix that up in a v3?
