Adding sysfs attributes to an already created device raises no userland notification. Instead of fiddling around in the depths of busses and devices I reuse the event char device (module hid-roccat). This device gets now created with a hardware specific class that contains the device attributes. For this I had to introduce support for binary attributes into struct class. This is afaik the easiest way to achieve said goal. If these patches get applied I can upload a new version of my userland tools that is compatible with old and new drivers in an instant. As there are quite a couple of unapplied patches flying around, I decided to base these patches on 2.6.37-rc2 and designed them to contain everything pending and so make all unapplied patches obsolete. -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
