I have the following device that udevadm lists as:

looking at device '/devices/pci0000:00/0000:00:1c.7/0000:09:00.0/usb6/6-2/6-2:1.0/ttyUSB0/tty/ttyUSB0': KERNEL=="ttyUSB0" SUBSYSTEM=="tty" DRIVER==""

looking at parent device '/devices/pci0000:00/0000:00:1c.7/0000:09:00.0/usb6/6-2/6-2:1.0/ttyUSB0': KERNELS=="ttyUSB0" SUBSYSTEMS=="usb-serial" DRIVERS=="pl2303" ATTRS{port_number}=="0"

looking at parent device '/devices/pci0000:00/0000:00:1c.7/0000:09:00.0/usb6/6-2/6-2:1.0': KERNELS=="6-2:1.0" SUBSYSTEMS=="usb" DRIVERS=="pl2303" ATTRS{bInterfaceNumber}=="00" ATTRS{bAlternateSetting}==" 0" ATTRS{bNumEndpoints}=="03" ATTRS{bInterfaceClass}=="ff" ATTRS{bInterfaceSubClass}=="00" ATTRS{bInterfaceProtocol}=="00" ATTRS{supports_autosuspend}=="1"

So I created the rule:

KERNEL=="ttyUSB0", SUBSYSTEM=="tty", SUBSYSTEMS=="usb-serial", DRIVERS=="pl2303", KERNELS=="6-2:1.0", SYMLINK+="cc128serial"

this doesn't work.

However if I do:

KERNEL=="ttyUSB0", SUBSYSTEM=="tty", SUBSYSTEMS=="usb-serial", DRIVERS=="pl2303", SYMLINK+="cc128serial"

then it works. I tried with KERNELS=="6*" etc.. to no available

any ideas ?

thanks
