Hi there. Same problem as before. 3900 not recognized after waking up from sleep
But, I’m particularly annoyed right now. It seems to be related to removing the dock, sleeping the computer, waking the computer, reconnecting.
I find it fails, then i switch USB ports and it works. Then next time it fails, I need to reboot the PC.
Been rebooting a couple times a day.
PS. This dock is amazing, except for this.
