Nice imperia, thanks for the report here. First we need to be sure it's exactly the same adapter. Can you provide the the output of "lspci -nn" ?
Then, if it's the same adapter: 0) Which Ubuntu version are you running? Which kernel version are you using? Can you try in the latest 4.13 for Xenial? (or even better, the hwe-edge 4.15) Instructions to run the latest 4.15 version: https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/unstable?field.series_filter=xenial 1) You said "after some hours" - can you provide some details? You've been using the USB tuner for like 2 hours? 12 hours? The tuner is in constant use and suddenly the issue happens? 2) If possible, enable xhci dynamic debug and provide logs after the issue; in order to do this, run the following command as root: echo "module xhci_hcd +flpt" > /sys/kernel/debug/dynamic_debug/control After issue reproduces, collect the /var/log/kern.log file.

Our next approach is to modify the patch a bit and re-test. This LP will be used to document our progress in the investigation.
