I am using Vista 64-bit with XP 32-bit in VirtualBox. The main reason for using virtualization is the unavailability of a 64-bit driver for a reprogrammable USB FPGA board. This little board can be programmed using a utility (Adept Suite) of the manufacturer (Digilent). I added a USB filter for this device in VirtualBox and it got detected in the guest OS and installed the correct driver for it. It appears as enabled and working in Device Manager. The utility can also detect the board and its ID. However, when it tries to communicate with it (Initialize Chain) it fails. I can confirm that this same setup with another virtualization software works and the utility can communicate to the board. I would gladly provide any kind of dump, log or other debug data for investigation. ",defect,reopened,USB,VirtualBox 1.5.6,,USB appears working no communication,,other,other
