Hi Mauro, is there a chance that we can clean up the em28xx debug module parameter mess ? There are currently 8 (!) of them. Do we have to maintain them all forever as "stable userspace interface" ? For example: - "reg_debug" is actually used for usb control message debugging - "core_debug" is abused for usb isoc debugging and not used for anything else - there is a module parameter "isoc_debug", too, but it is used by em28xx-v4l only ...
