ASIO4All may or may not work. I just spent the afternoon trying to use Fuse and took it off. Not only would it not start but a couple of times and then it just hang there saying it is loading up. I have a Mustang III V.2 amp and will use the headphone out to record which disconnects the speaker and simulates the amp cabinet and speaker, but the line out of the amp ( low impedence) for hooking up to a mixer board or other input to amplify the amp I guess does not disconnect the speaker on that amp. I tried the USB connection and my RME Babyface is a USB connection for my sound card, and I tried all I could and when I looked at the Fender folder in Windows, the only thing it had *.inf files on was Mustang I and II amps and the GEC-Dec whatever it is amp I guess is what it is.
Fuse does not work on my computer and I could not really decide if I needed a firmware update or not since I have V.2 of the amp and the download was 2.1 version. It really did not look as if I needed it, and besides the software would not start up. I un-installed it, un-installed IE again which I do not want on my computer since I use Firefox, and microsoft Silverlight is already on my computer, so I fail to see why I need those to use that program in the first place.
Simply put, it was a pain and I wasted enough time on it.
I have ASIO drivers on my RME Babyface, and will use if necessary the headphone output to record which is what that is also made for - on both amps and the other amp is not a Fender.
Fuse just sucks as far as I am concerned.
Anyway what I read is that you can only record you can not listen to it back through the USB connection anyway, as it is not really a sound interface so you would have to use a soundcard or audio/interface and the Mustang Amp was listed in Device Manager as a Sound, Video, Game Controller Device and like I said I even disconnected my RME Babyface from USB just to try and use that Fuse software which never did work at all.
I took it all back out again and never will try it, unless they actually get that software to work, and my computer is not the problem.
Well, that's about it.

Oh, and my RME Babyface my regular audio/interface has its own ASIO drivers and usually any manufacturer of an audio/device with its own ASIO drivers are way better to use then ASIO4ALL and I am not sure but I do not think you can have two devices using ASIO at the same time running on the computer. Not sure about that, but that whole episode wrecked my afternoon on my computer, looking at the instructions which do not tell you that you need ASIO drivers for the USB connection anyway with Fender at all. The only thing it put in on that Mustang was USB composite device and a couple of other drivers - no ASIO drivers did I see or did Fuse put on the computer that I know of. Maybe I should check that and I will.
