Re: [Xen-devel] porting pvusb drivers to pvops kernel

[Noboru Iwamatsu <n_iwamatsu@xxxxxxxxxxxxxx>]

Hi,

I was preparing to post the pvops version of pvusb,
but, it has not finished and is still pending.

I don't have enough time for it for the time being.
I hope I can post it until the next xen release.

If someone want to work for it, I'm okay with that.

Internal of the Pvusb and the usbip are very different
except for the point that they use usb drivers interface.

I don't think it's good idea to share the code.

Thanks,
Noboru
