It was 9600 usually, but probably it should be 112500 now, as Vladimir
wrote.
If you want, you can ensure some speed on GRUB side by parameter -s ,e.g.:
serial -s 112500
>> serial
>> terminal_output console serial
>> debug=all
>> insmod ohci
>> insmod ehci
>> ls

Something changed in GRUB in the meantime, so try this for current trunk
code:
serial
terminal_output console serial
debug=all
nativedisk
ls
> My mistake, the adapter is not a null modem.
At least these pins must be connected by null-modem cable:
3 - 2
2 - 3
5 - 5
This is valid for "classic" 9pin PC connectors on both sides of cable.
You can check the cable by ohmmeter if it is correct.
Additionally:
There exist some important USB related patches which are not included in
trunk yet - see the history of mail list and search for posts from me
and Melki Christian some weeks ago.
BR, Ales
