Hi

Every time I try to get Pro Tools LE 7 working in Virtual Box on Snow Leopard Server it generates the following message
The machine is a MacbookPro 9.1 running OS 10.8.5

Failed to attach the USB device Digidesign Mbox 2 [0140] to the virtual machine Snow Leopard.

USB device 'Digidesign Mbox 2' with UUID {a8504fe7-d71f-41f9-8e2e-3492e93cde56} is busy with a previous request. Please try again later.

Result Code: NS_ERROR_INVALID_ARG (0x80070057)
Component: HostUSBDevice
Interface: IHostUSBDevice {173b4b44-d268-4334-a00d-b6521c9a740a}
Callee: IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}


I've tried to activate the mbox in the menu and by the menu bar but nothing seems to work.

Any advice on this would be great

Thanks

Create a USB filter. User Manual, Chapter 3.10.

When creating the filter, try one with just the Vendor and Product ID first.
