I'm afraid that an user may repeatedly plugs in and off a device using this driver (for some reason), and finally gets an error. Since dvb_pll_devcount and "id" module parameter are just used for debugging purpose to override/force PLL type, removing them totally would be better, IMHO. regards, Akihiro
