Your symptoms look like 3.1.3. > and second this card is the only device connected to that port. All devices on a bus share bandwidth. While it is possible to have devices with different speeds on the same bus, a lower-speed device will eat as much bandwidth as it would on a lower-speed bus. Furthermore, the scheduling of the translations imposes some additional restrictions; the EHCI driver still has some bugs there. You should have three or four buses; see lspci. To find out which port belongs to which bus, you have to plug something into each one in turn. > For some reason I do have to use the usb-audio instead of the snd-ua101.
