OAC will not install or operate properly on Symbol (Motorola) devices running Windows Mobile 5. This is a known issue and Symbol is working to solve the issue. The problem is Symbol's Fusion supplicant which is incompatible with any supplicant like OAC and 3rd party virtual adapters. Symbol does have a customer WM5 image for the MC9090 on which Fusion has been removed and replaced with Windows Zero Config. OAC is able automatically to disable WZC on WM5 just like it does on XP.
