[pve-devel] [PATCH] usb2.0 as default + usb-tablet hotplug/unplug

Yes, after reading the doc, it's going to uhci controller is usb1.
As we use only ehci.0 bus, it's plugged on this bus, but goes to the companion uhci.


>>Is there any need to remove the emulated uhci controllers? I guess they do not need and 
>>resources if there are not used? 

No, we can keep it. (I just thinked it wasn't require for usb1 passthrough).


Any objection to always activate ehci by default ?
Like this we can hotplug/unplug tablet.


I can remake the patch if you agree.

I guess to the uhci controller.

Is there any need to remove the emulated uhci controllers? I guess they do not need and 
resources if there are not used?
