Hi - I've read through various posts on this but no solution has met my problem. I have a Windows 8 64 bit machine with Mac OS Snow Leopard Guest.
Using VB 4.2.8.

I have configured the USB setting and created the iPhone filter. Yet I get the error below when selecting the iPhone from the Device menu:

Failed to attach the USB device Apple Inc. iPhone [0330] to the virtual machine OSX.

USB device 'Apple Inc. iPhone' with UUID {f859d0fe-eb84-4521-bd18-908d81a5ca86} is busy with a previous request. Please try again later.

Result Code: E_INVALIDARG (0x80070057)
Component: HostUSBDevice
Interface: IHostUSBDevice {173b4b44-d268-4334-a00d-b6521c9a740a}
Callee: IConsole {db7ab4ca-2a3f-4183-9243-c1208da92392}

Anyone who has experienced this and know a solution please help me!

Thanks.
