how long does it work until "Sequence Error!"?
any hints that it happens in regular intervals?

only if yenta is in front of uhci_hcd interrupt handler chain wise.
just recheck after
	$rmmod yenta

might make sure its gone with
	$lsmod
post above.

it looks like something keeps the usb's interrupt from being handled right in time.
like

 harddisk: dma enabled?
	$hdparm /dev/hda
post above also.

	$telinit 3
