Hi all,
when assigning USB host devices to a guest using the hostport option,
there seem to be different formats, when calling info usbhost:
- On my vanilla kernel linux there is a hostport format e.g. "1.5" or "1.2"
- On my Debian 6.0 full blown linux there is a hostport format "2" or
"4", that means, there are no dots and only one number
Hmm, is this on the same machine, with the usb devices hooked up the same
way? Normally these differences come
from there being hubs in the chain, ie "2" or "4" indicate devices plugged
directly into a root hub,
"1.5" and "1.2" mean devices plugged into a hub, which itself is plugged
into root port "1"

No it's on different machines - first with Intel Hardware, second with AMD
Hardware. I have no hubs attached, I use the ports that are offered
directly on the mainboard (EPIC Nano Connectors / ATX rear side panel). On
all other Intel systems I see the same effect with the "1.x" ports. Only
the AMD system shows the single numbers.
Maybe the root hubs are different on Intel and AMD hardware?
Best regards,
Erik
