I have tested the patch and it worked without problems. Testd-by: Akihiro Tsukada <tsk...@gmail.com> I could not noticed the bug because the device was registered without any error messages, and it seemed to work even with the bug. (Though actually I was wrong and missed that the device does not work after reboot or re-plugging). After applying this patch, I have confirmed that the device now works after reboot/re-plugging without any problems. note: The patched func: gl861_i2c_read_ex was used in device's early init, called from d->props->power_ctrl (from dvb_usbv2_init). But dvb_usbv2_init does not check the return value of it, and if the device had been initialized previously it can work even with the interrupted init process in power_ctrl(). -- Akihiro
