Good to know, thanks for this input. The detach is probably a default behavior of libftdi... Will have a look at that. Having kernel level gpiolib would still have advantages: It would make the matching of the GPIO's and tty device easier, since with this patch the gpiolib device is a sub-node of the usb-serial device in sysfs and the user would have to use kernel interfaces only (no libftdi)... -- Stefan -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in Please read the FAQ at http://www.tux.org/lkml/
