[Bug 88746] Re: ehci_hcd module causes I/O errors in USB 2.0 devices

[Mike Berkley]

Just purchased a new Shuttle PC, SA76G2 with an AMD 760G chipset.  Tried
to boot from an Ubuntu 9.04 USB stick. Failed.  Tried to boot from a USB
CDROM with a 9.04.2 CD.  Failed.

Finally, I went into the BIOS, set it to have "All of USB device
operated on full/low speed mode" (quote from the manual).

USB stick booted first time, and I was able to install Ubuntu without
errors.  It was slow, but no errors.

This bug with high speed USB storage devices is a big issue.  If I was
not an expert and hadn't known about the bug, I don't know how long it
would have taken to diagnose this install problem.
