Nonetheless, at the previous patch
(0846e7e9856c0928223447d9349a877202a63f24, usb: Add support for indicating
whether a port is removable) things work.  With this one, they don't.

It's Rawhide, updated yesterday.  "Removable" says "fixed".

FWIW, power/runtime_status reads "suspended" most of the time.  By banging
on the keyboard I can get it to "active", but it goes back to "suspended"
even with continuous activity.  Weirdly, the keyboard continues to work if
I keep hitting keys.

Thanks,

jon
