Thread-topic: x86_64 Dom0 USB support (was [Xen-devel] Xen on ES7000 x86_64 take 2)
I meant to post this sooner but it skipped my mind. I solved the USB
keyboard issue on the ES7000 x86_64 box. The Dom0 kernel by default did
not have any host side USB drivers compiled in. Once I fixed this the
keyboard worked.

I noticed that on x86_32 Dom0 kernel, the host side USB drivers are
enabled by default and on x86_64 Dom0 they are not. Is there a reason
for this or should I be submitting a patch which enables this support?
