Again, the Firewire Solo thing
Well, after I got the Firewire Solo working again with Windows XP, I switched back to Mac OSX, and indeed it asked for doing a firmware upgrade up somehow didn't get thru. Then I rebooted (by menu proper, instead of hardware force reboot) back to Windows XP, and the Firewire Solo still works with Windows. Fine. As long as it works with Windows, I am not wasting time messing with it on OSX anymore.
Such a mess.
Such a mess.
