RE: [Xen-devel] [PATCH] USB support

["Dugger, Donald D" <donald.d.dugger@xxxxxxxxx>]

Anthony-

Not knowing when the move to 0.8.1 will get done (although I know it
should be soon) I wanted to get this out now, especially since the
changes aren't that extensive, it's mainly the new USB files.  The
current Windows guest under VNC is so much better with the USB tablet
mouse that I thought it was worth the effort to provide this as an
interim solution.

I must have missed your SDL patch, I'll go find it.

Tnx for the pointer about the evdev, I'll have to try that (although I'm
pretty sure `gpm' still doesn't work with the USB tablet).
