First time poster here so forgive me if this problem was addressed in another thread, I've searched and could not find anything.
I bought the Fiio e7 and e9 combo about a year and a half back, and a few months ago my computer stopped recognizing the combo when I connect via USB.
The e7 works as a stand alone unit, the e9 also works as a stand alone unit via the 3.5mm input in the back.
Any insight anyone can give me would be greatly appreciated. Thanks in advance.
