Please take a second look at this information:
I do not understand what type of problem not related to the driver, that you are referring to; if you can give me a few examples I can test that theory; which is what I have been trying to do with my troubleshooting file, configuration of Audacity is very simple, and works in Windows: http://vetshelpcenter.com/media/troubleshooting-gr-55.txt
My document on driver activity in Windows, using Audacity to record Audio, Guitar Pro 6 to record MIDI and the GR Floorboard to get Patch's, which I have no problem getting this working; keep in mind I'm a Unix programmer (30+ years), not Linux per say, but I'll work on that; but I'm not a Windows End User, nor a Noobie; but I'm not in the best of health; we all have our problems, I just don't want this interface to be mine. http://vetshelpcenter.com/media/GR-55-USB-Anlyzer.html
I do not see evidence that this driver patch is working as it should; but its a good start, and I thank you for your work; now it shows up in the system, and I do have limited access to the audio input channel; so we are working in the right direction; but its far from saying that the low-level part works; when I can only get one function working with limited (still crashes) success.
Lets step back and look at this with Fresh eyes:
This is the Roland GR-55 Guitar Synthesizer http://www.rolandus.com/products/productdetails.php?ProductId=1148
You based this driver patch on the
BOSS JS-8 http://www.bossus.com/gear/productdetails.php?ProductId=1027
Instead of the GT-10; which seems more similar, but I do not know anything about the difference in drivers, nor do I know that you have a working driver for the GT-10, or that its based on the JS-8.
BOSS GT-10 http://www.bossus.com/gear/productdetails.php?ProductId=941
As such, all I can do is go along and see if I can get this to work; so humor me, and lets see about basing this on the GT-10 and see how that works; from what I read; they might be based on the same chip set; I have contacted Roland, and they refuse to tell me what chip set they do use; I can open up my GR-55 to see what chip set its using; its new, and I hate to do this; but I did; below are my findings; but I still do not know what chip set the GT-10 or JS-8 use; but I'm sure someone knows; so maybe this is a better place to start.

I did a search with no results; so maybe this doesn't help at all; but I had to try; my guess is that these are custom chips; Yamaha would be my guess at manufacture; but I don't know that.
The work you do is very important to the community and I thank you.

Does this type of data (USBlyzer Report) help to write drivers? http://vetshelpcenter.com/media/GR-55-USB-Anlyzer.html
The problems you're still having are not related to the driver anymore. The low-level part works. You're just facing a configuration thing with the applications you're trying to use, but I don't see it at the moment. It's most probably something trivial - can anyone else on this list have a look at the comprehensive logs you've been posting?
Thanks, Daniel
