DLPLCR4500EVM: USB Driver Problem

Part Number: DLPLCR4500EVM
Other Parts Discussed in Thread: DLPC350

Tool/software:

My device displays the default screen well, but is not recognized by PC even if i connected 12V power and mini USB.

When I checked Device Manager and DLPLCR4500 GUI 4.0.0, there might be USB Driver Problem.

Please check what i have to install.

Thanks.
