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:

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.
