Ghost IR Code sent from 5922 if on ssUSB port (USB3.0)

Hello,
I just noticed that my console was scrolling automatically in my bash history when connecting a Tuner 5922 on USB 3.0 port.
The behavior when 5922 is connected on USB 3.0 is like the 5922 connected on USB2.0 and when using RC to send [upper arrow key].
Is it expected that TBS devices are not expected to be connected on USB3.0 (ssUSB Port) ?
This is on laptop HP EliteBook 8540p using Ubuntu 13.04 and TBS drivers v130927.
Thanks

Hello,
I have the same issue! If I connect my 5922 to USB 3.1 port I see ghost KEY_UP key commands every 2-3 seconds.
Also I noticed that there is quiet screeching sounds coming from my mainboard when there is USB activity from the tuner usb device. Later I discovered that the 5922 also have screeching sounds when connected to mainboard. If I disconnect the usb cable the sounds are gone! 3.0 ports don't make KEY_UP commands but the screeching is still present
Did you finally found what is the problem? Defective 5922 or maybe its PSU.. Or mainboard?

No I did not found a real solution, my chance are that affected computers are not used from main UI when installed. When I need to use main UI, I disconnect the IR input device:
In case of TBS tuner sending IR code leading in unexpected arrow UP key pressed:
1) Execute the command xinput list to list your input devices.
2) Locate AT Translated Set 2 keyboard and take note of its id number; this will be used to disable the keyboard. Also, take note of the number at the end, [slave keyboard (#)]; this is the id number of the master, which will be used to re-enable your keyboard.
3) To disable the keyboard, execute the command xinput float <id#>, where <id#> is your keyboard's id number. For example, if the id was 10, then the command would be xinput float 10.
4) To re-enable the keyboard, execute the command xinput reattach <id#> <master#>, where master is that second number we noted down. So if the number was 3, you would do xinput reattach 10 3.
