I can tell you honestly...In terms of USB cable I've always used what ever one was laying around, typically one of the ones from Line6.
In as much as mocking people with problems.....I find that strange and I'll tell you why. I dont fault anyone who has a question and needs an answer, comes here and gets that answer. Even if you didnt read your owners manual or update instructions. Please answer my question.....thanks for the answer...done is done. What prompted this post and what I do mock is the following...and I've read plenty like this. Hey line6 you clearly screwed up the update cause my machine is messed up and I blame you. The Best part.....I'm a genius programmer and could most likey build my own Helix ..but I allow Line6 to do so on my behalf. Of course no matter what the suggestion is...the suggestion is treated as if the person taking the time to help is blowing smoke up your skirt. I'm no expert....but does it hurt to know your computer is functioning properly before you update. Chances are most people just let things go until they have a problem...to late. What does any of this matter to me? After reading so much of this stuff and I think morale among some who answer the questions has become stressed....I wanted in my own silly way to let those who help others here and those who create these products have done a great job. Some of you simply embarrass yourselves. OK...group hug...or not!
