Hi,
with kernel 4.4 (Ubuntu 4.4.0-28.47-generic 4.4.13), this option setting
in /etc/modprobe.d/*.conf seems to block proper initialization:
options dvb_usb disable_rc_polling=1
Without this option, firmware for the frontend 'm88ds3103' is loaded on
first access (see second log below). When the above option is set, this
initialization is missing (see first log below).
Hardware used:
# lsusb | grep TechnoTrend
Bus 003 Device 011: ID 0b48:3011 TechnoTrend AG TT-connect S2-4600
Steps to reproduce:
* Disable software accessing the tuner.
* Unplug the tuner's usb connection.
* Add options dvb_usb disable_rc_polling=1 in /etc/modprobe.d/*.conf.
* Reboot.
* Plug in the tuner's usb connection.
* Tune to a transponder (w_scan -fs -I w_scan-initial-tuning.txt)
The faulty initialization sequence is:
