D34010WYK USB host controller

Hi all,

I see that the NUC has 3 internal USB hubs:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

However, it seems no matter which port I use for plugging an USB2 device (a TV tuner), it gets plugged in bus 002.

Bus 002 Device 004: ID 2013:024f PCTV Systems nanoStick T2 290e

If I plug in an USB 3.0 device in the same physical port, it will be connected to bus 003.

Bus 003 Device 002: ID 174c:5106 ASMedia Technology Inc. Transcend StoreJet 25M3

Before I start to fiddle with the NUC, I'd like to ask if the internal USB header is connected to the same bus as the ports in front/rear? In other words, will all USB 2.0 devices always share the same BUS on the NUC?

Re: D34010WYK USB host controller

The reason why I'm asking, is that I have two HD TV tuners that both work alone fine, but if I plug in both, neither of them works ok. I've ruled out power issues already by using a powered USB hub, but next I'd like to plug the tuners into different buses to see if that could help.
