On my Linux VMWare Horizon client (v4.5.0 5650368) it doesn’t seem to matter what choice I make about NOT Connecting USB Devices at Startup it still continued to take over my Logitech USB Receiver. I’d have to use the keyboard and navigate the menu so I could get control of my mouse back. Thankfully I don’t have a Logitech keyboard that uses the same receiver. It was an easy fix, but I don’t know why it does it. The permissions to the ~/.vmware folder and files all seem OK. IT’s an easy fix of just editing the file view-preferences and amending the line or lines as follows.
$ vi ~/.vmware/view-preferences
...
view.usbAutoConnectAtStartUp = "FALSE"
view.usbAutoConnectOnInsert = "FALSE"
...
