It seems that subsequent tuning makes the device worse, reducing the maximum effective packet bandwidth. Btw, this happens with both xHCI and EHCI drivers, so, it is not related to any USB 3.0 issue. Enabling some demux logs, it is possible to see that there are too many FEC errors: [73514.186880] dvb_dmx_swfilter_packet: 4546 callbacks suppressed [73514.186933] TEI detected.

It would be good to see if others can use it and tune to several channels. > Ah, I didn't work at the remote controller yet. I'll handle it after > doing more tests with the DVB functionality. Remote controller support was added.
