Thank you very much: that's great news. I don't think my hardware is

I'm not sure if this is a problem with the
EHCI driver or your USB
controller,
Okay, I found two bugs in the EHCI driver that explain all your
problems. Apparently, these bugs show up only if the USB host
controller issues interrupts not for every completed microframe; you
seem to be the only one with such hardware. I've CC'd you on the patches; holler if you
need entire files.
Got them: I'm just about to reboot & test, so I'll let you know what
happens shortly.
Thanks again,
Colin.
