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

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

Anthony-

Indeed, we are a little behind the times.  I was hoping for a standard
mouse that didn't require extra patches but then I've always been an
eternal optimist :-)  It makes life a lot easier when you're trying to
install an unmodified fully virtualized guest.  At least with the
Summagraphics it's just some config files that need to be changed,
nothing else.

Oh well, I guess we work with what we must.
