Looks good, but unfortunately it has been whitespace damaged (tabs replaced by space, e.g. by your mailer) and doesn't apply. I could fix it up for you if you prefer, but it's probably better if you get this fixed on your end so you're all set for your future contributions. Try sending the patch to yourself first and make sure you can apply it with git-am. Take a look at git-send-email too for sending. Please also add a "USB: serial: pl2303: " prefix to the Subject line and shorten the current subject somewhat (e.g. "add support for PL2303GS"). For completeness, please also include the output of "lsusb -v" for this device. It can replace the log snipped above. > --- > diff --git a/drivers/usb/serial/pl2303.c b/drivers/usb/serial/pl2303.c > index a70fd86f735c..1072f8eb6ab9 100644 > --- a/drivers/usb/serial/pl2303.c > +++ b/drivers/usb/serial/pl2303.c > @@ -435,6 +435,7 @@ static int pl2303_detect_type(struct usb_serial *serial) > case 0x105: > case 0x305: > case 0x405: > + case 0x605: > /* > * Assume it's an HXN-type if the device doesn't > * support the old read request value.
