Sorry, I do not have a solution yet.
I discussed this for another opinion, and it was agreed that we don't know the reason for this. I have heard a few isolated issues which involve conflicts in certain equipment. The drivers are suspect, so if you can find a different driver, your problem may clear up.
USB is strange, because it is so complicated. My opinion is that it is so complex, that some equipment must have a special or limited version of it. USB 'school' can run months long. I only know of one certified USB graduate, and even he gets lost in certain parts.
I have seen a few odd things happen. One problem was with one model of Dell computer. Another was with a HP laptop, again only one model. Other devices present can cause problems.
So, if you have another computer, try it. If not, reset again, and only add one device at a time. Also, try a different port.
