Aha, the axe method.... :)
Nope, it is a rack server with little use for USB. A rather nice one
with video and USB at the front. But currently we're using the ps/2 kbd
interface at the back, where there's also a video interface.
Out of curiosity:
Are the ISR's really shared, or is it more an "optical" problem?
em0 is at irq 30
uhc is at irq 16
The server will be here for at most 1 more week, and is available for
tests....
