TPS65910 EVM connection to PC

Other Parts Discussed in Thread: TPS65910

Hello,

I'm trying to connect the TPS65910 EVM to my PC via the USB to GPIO Interface Adapter for the first time.  When I bring the software up, I get the following error: "I/O Subsystem not functional, unable to load firmware version.  Check to see if device is connected."

I have 4V connected to VCC_IN, J13-J14, J18-J20 are all depopulated.  The USB adapter is connected to J1.

Does anyone have any suggestions?

Thanks
