|
+There also is xhci host controller support available. It got alot
|
|
|
|
|
+less testing than ehci and there are a bunch of known limitations, so
|
|
|
|
|
+ehci may work better for you. On the other hand the xhci hardware
|
|
|
|
|
+design is much more virtualization-friendly, thus xhci emulation uses
|
|
|
|
|
+less ressources (especially cpu). If you wanna give xhci a try
|
|
|
|
|
+use this to add the host controller ...
