Hi,
After some troubles with my scanner, I've decided to test how some other
devices work when they're connected to the USB3 port instead of the USB2
port. This time, I plugged in a hybrid analog/digital tv stick and
started tvtime, with usbfs_snoop on.
Dmesg for USB3 port:

No overruns occurred here. I have to admit that the device has its
problems on USB2 too that even require a reboot sometimes as no devices
are being detected anymore (on all USB2 and USB3 ports), but it works
most times.
