[pve-devel] USB Host passthrough high cpu / interupt usage

[Stefan Priebe]

Hi,

i'm trying to pass through 5 usb devices from the host to the guest. 
What i'm wondering is the very high interupt and cpu usage of the guest.

These usb devices i'm passing are just tty / serial ones - so the data 
transfer is VERY low.

Does anybody habe an idea? Latency for USB data is also very high around 
130ms.
