I've spent some time looking into that but I haven't found the problem, yet. Maybe Jiri can comment here. > Also, how does the HID subsystem differentiate from HID protocol > versions?

There is already a "version" field in UHID_CREATE. It isn't mandatory, though, so setting it to 0 works. I even think the HID core doesn't even look into that value except for printk messages. > -- > João Paulo Rechi Vita > Openbossa Labs - INdT Thanks David -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
