is ehci built-in in jaunty? dmesg says it's using ehci even though I
don't see it in lsmod. Anyways, now I can't even workaround by
downgrading to usb 1.1

Yes, it is built in. I believe as a part of the general 'speed up the
boot process' work that's taking place.

(Change load order in initrd image) did indeed fix it for me. I rebuilt
the initrd for my kernel.

Ugh. I spoke too soon. I had ehci blacklisted. In summary, unplugging
the Alcor Flash reader allows me to keep ehci, but leaving it in causes

I experienced this bug as well. I tried all the fixes in this thread as
well as other sites but nothing worked. Sometimes my usb would die and
lose all power and a restart wouldn't even bring back power. I could
unplug and replug in my flash drive and it would be assigned a new
address or I would
sorry got the link wrong in the previous post. The correct link is
http://search.luky.org/linux-kernel.2003/msg70535.html. It proved to me
that the kernel can crash aspects of bios. I have a usb mouse as well
but I wouldn't lose that when the usb crashed in bios. Maybe it uses usb
1.1 transfers.
I don't know how to edit posts but I just had the flash drive stall on transfer
of files to my computer but at least it didn't lose all power like before.
Still geting the usb 1-7: device descriptor read/64, error -110.

for everybody. I'm guessing it's just covering up the error in your
case.
