[SeaBIOS] Booting from USB cdrom device doesn't work

[Sven Schnelle]

Hi List,

i have seabios running on a Thinkpad T60 with coreboot and seabios as
Payload. When trying to boot from a USB cdrom, i get the following errors:

Booting from DVD/CD...
wait_td error - status=184007ff
uhci_send_bulk failed
USB transmission failed
wait_td error - status=184007ff
uhci_send_bulk failed
USB transmission failed

read capacity failed
atapi_is_ready returned -1
WARNING - Timeout at wait_td:427!
uhci_send_bulk failed
USB transmission failed
Boot failed: Could not read from CDROM (code 0003)

I have no knowledge about USB, so if anybody could
help me in interpreting those messages, or has an
other idea what the problem is, that would be great.

Thanks,

Sven
