Just upgraded to Windows 10 2004 on 2 laptops. I upgraded my smaller HP first and the speakers came up as Bravo-x ONCE! I figured GREAT, 2004 fixed the issue. I upgraded my main Dell Inspiron laptop and....nothing. Same issue with "USB Composite Device, Error code 10" that I've been seeing since they stopped working. I connected them again to my HP and nothing...No more Bravo-x, just "USB Composite Device". Does this mean my speaker's USB interface is broken? Why would it work once? And what the heck is "Bravo-x" that shows up on Windows AND Mac? This is maddening. If it didn't tease me by working once, I would forget about it.
