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 > I didn't get anything captured, sorry...

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.
