2011/5/24 Jeremy Jongepier :

The current mode a soundcard is using. Knowing both would be helpful.

lsusb gives a hint for the hub mode:

$ lsusb
Bus 010 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 009 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

$ lsusb -t # adds information about ideally possible transfer speed.
/: Bus 10.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/2p, 5000M
/: Bus 09.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/2p, 480M
/: Bus 08.Port 1: Dev 1, Class=root_hub, Driver=uhci_hcd/2p, 12M
