Thanks for your providing info and screenshots.
I also found similar issue on Fusion http://communities.vmware.com/thread/187469?start=0&tstart=0 , so I think the reason may be caused by the USB device has multiple interfaces (Storage, Keyboard/Mouse/HID) and Keyboard/Mouse/HID are blocked by default for View Client. Please try below workaround, I'm not sure whether this workaround works for you since I don't have this device on my hand.
Steps of workaround:
1. Open Terminal.app
2. Execute command as root "sudo defaults write com.vmware.viewusb AllowKeyboardMouse 1"
3. Execute command as root "sudo defaults write com.vmware.viewusb AllowHID 1"
4. Execute command as root "sudo defaults write com.vmware.viewusb DisableRemoteConfig 1"
5. Quit View Client and relaunch it
6. Login to server and connect to desktop
7. Enable "Automatically connect when inserted" in USB menu
7. Plug in the device
Thanks,
