this my upgrade step,hope will helpfulThanks for the info. I have to say that my own experience differs from yours (that's not to say it is exhaustive or definitive). But I have used all versions of USB since they were invented and I have encountered any of the issues you mentioned. The only problem I've ever seen is if I mistakenly connected a device that required USB 3.0 using USB 2.0. I did try a single cable from a USB 2.0 port on the front panel of my computer, with no luck. And none of these are what I would consider a long run. None of these are longer than four feet.
I also note that the update app says "Disconnect" (sic) in the lower left corner, in red, right from the outset and that never changes. Furthermore, the Exit menu command doesn't work. I have to click the X on the upper right of the UI to close it. So, I have to wonder if this whole problem is a software issue.
