Hi Andrej,
I contacted the original creator of the patch that you used previously
(Xgaz on Ubuntu.it forums).

He passed this suggestion to me (coming from a Spanish user):


For people having the kernel message "af9035: recv bulk message
failed:-110", it's due a problem with the power save mode. To solve it,
create the file "/etc/modprobe.d/options.conf" with this content:

options dvb-core dvb_powerdown_on_sleep=0


So basically you may need to disable the power saving functionalities to
make the device working again.

Since the only functional difference between the old and the new patch
version is in the remote code (which I removed), probably this code was
preventing your device to go into sleep mode, so it was hotter but
worked fine.

Please report if this helps.

Regards,
Gianluca
