Was there a simple fix for this?
It just happened to me with 3518 and 2 USB devices (a SATA DoM & a USB meme-stick).
Then tried v6 update4 & that was fine.

Only possible factor was that we booted into the default 64bit mode & changed boot architecture to 32bit. Maybe if we booted to 32bit (ie. manually selecting it), then changing it to 32bit may havew been different, but who knows! Cheers.
