Hmmm... This log agrees with the earlier one, right up until the first
READ command occurs. Then the earlier log has a timeout (no data
transferred) whereas this one continues perfectly.
As far as I can guess, there's some weird problem with the ehci-hcd driver
-- it doesn't like something about the initial boot-up environment. (But
then how come the Lexar device boots okay?)
The following is sheer speculation. Several other people have noted
problems with ehci-hcd that sometimes go away if they unload the driver
and reload it. Can you do the same sort of thing? That is, include
rmmod ehci-hcd
modprobe ehci-hcd
somewhere in the initial boot-up sequence (such as an initrd linuxrc
script)?
