Re: Unable to boot from external USB DVD drive

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

:Ok I have made a slight progress. It seems that the BIOS was configured to
:always use USB 2.0 (480Mbps), after switching to 12Mbps, the drive got
:recognized by the kernel at /dev/cd8 but mountroot still failed (and
:keyboard didnt work). Why cd8? I guess this is related to not using ehci
:by default. Why are we still not supporting USB 2.0 out of the box?

    Ach.  It's my fault.  USB devices assign units starting at 8 so as 
    not to create confusion with da/cd assignments from AHCI or SILI.
    The boot code tries da8 automatically but doesn't try cd8 automatically.
    Easy to fix.  I'll have a commit in place in a few minutes.

    I do not know why the keyboard isn't working.
