Ensure your system has USB 2.0 available!!!
My guess is that part of the problem is the handset doesn't communicate well with USB 3.0, some things are basic as in 'what is it that's attached' 'the connected device needs driver "X" to use it' but on actual communication there's too much of a speed difference.
That's my guess anyway as doing the previous in my postings my system never had a problem with connected device
