Well, on Linux it enables the Midi ports but it also forces capture/playback to 48k/96k at 24 bit. In my experience, the latter is what borks the USB communication as there isn't enough bandwidth on USB 1 for full stereo duplex of anything other then 16bit, 44.1k. The Edirol "advanced drivers" for OSX & Win can somehow handle that, but of course the Linux drivers don't and you get hard locks. These devices were designed before USB 2.0, so they Roland/Edirol were doing non-standard tricks ...
In any case, the advanced mode switch *does* work with Linux, provided you only want to either capture or playback, but not both simultaneously. I'd imagine it would work with 1 input and 1 output, but I bet that's not an option at the driver level ...

Thanks Julian and Dan -
I've never known what that button did but now I guess i do - it makes the device fail.

Hi Miller,
Just spotted this and remembered you mentioned an Edirol UA25:
'I've found that with my Edirol UA-25 I have to disable Advance mode in order to make it work in full duplex with JACK.'

So I think this is confirmation that that can indeed sometimes happen (if it were just one of us perhaps it could have been a fluke).
