No usb devices in removable divices

Hi,

I try to change host system from ubuntu 12.04 TLS to 14.04 TLS. I also change from 32bit to 64bit. Works fine. Today I try to use my Wacom Tablett in Ubuntu 14.04. No wacom Tablett. No USB devices under removable devices. Restart vmware-USBArbitrator brings no effects. I restart ubuntu 12.04: All is ok. Is there a problem with 64bit Version of VMWare Workstation (Version 10.0.2)?

Thx in advance
