From 5ad1a55542dd69d2c6aa7db5ca79073d693bbfed Mon Sep 17 00:00:00 2001 From: Paul Bender Date: Wed, 17 Nov 2010 16:56:17 -0300 Subject: [PATCH] [media] rc: fix sysfs entry for mceusb and streamzap 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.
