Hi everyone! While reading through this forum I have seen many cases in which USB-devices won't work properly. So maybe my problem belongs into this category - but 'Ive still got some hope left: I'am running WinXP(guest) under MacOSX(host) and try to connect an Edirol UA-25 external Soundcard, which, when connected, does show up in parallel's USB-device list (activated) and is recognised by WinXP. WinXP says the device couldn't be started correctly (Error code: 10) and thus doesn't display it as a choosable audio-device. Since it is recognised by Windows maybe there's still an answer out there? Thank you very much, ludi89 PS: The device works flawless under bootcamp's XP
