Subject: [media] rc: fix sysfs entry for mceusb and streamzap Author: Paul Bender <[email protected]> Date: Wed Nov 17 16:56:17 2010 -0300 When trying to create persistent device names for mceusb and streamzap devices, I noticed that their respective drivers are not creating the rc device as a child of the USB device. Rather it creates it as virtual device. As a result, udev cannot use the USB device information to create persistent device names for event and lirc devices associated with the rc device. Not having persistent device names makes it more difficult to make use of the devices in userspace as their names can change. Forward-ported to media_tree staging/for_v2.6.38 and tested with both streamzap and mceusb devices: $ ll /dev/input/by-id/ ... lrwxrwxrwx. 1 root root 9 Nov 17 17:06 usb-Streamzap__Inc._Streamzap_Remote_Control-event-if00 -> ../event6 lrwxrwxrwx. 1 root root 9 Nov 17 17:05 usb-Topseed_Technology_Corp._eHome_Infrared_Transceiver_TS000BzY-event-if00 -> ../event5 Previously, nada.
