I just received my PCM3070RHBEVM-K and USB_MODEVM Interface boards yesterday. I followed the PCM3070EVM-K Evaluation Module User's Guide (slau331a.pdf) to verify the switch and jumper configurations, installed the PCM3070 Control Software (slvc367a.zip) as the Administrator on my 32-bit Windows Vista laptop without errors, installed the EVM to the MODEVM board, then plugged the MODEVM board into my laptop using a USB cable. To my horror, Windows did not install the driver as explained in the User's Guide. At this point I tried the PCM3070 CS anyway (with compatibility mode for Windows XP SP2 (SP3 not available in my Vista installation)), and got the result I expected of "EVM disconnected".
I called tech support today and spoke with John Gracia and was told there were no known issues getting the drivers to load. I kept trying to get something good to happen so I disconnected the EVM from the MODEVM board and plugged it in to the laptop. At this point, the driver loaded properly and my Device Manager displayed TI DFU class driver. I thought I might be getting somewhere! I then disconnected from the laptop and re-installed the EVM, plugged the USB back in and the control software still displayed "EVM disconnected".
It seems there is a problem with the EVM somehow. I measured the voltages on P23 and they are correct. I question the jumper and switch configuration on both the EVM and MODEVM boards since W1 has a factory installed soldered jumper in place, W20 on the EVN does not have pin 1 marked clearly, and many of the lower jumpers were installed when the default shows them removed. Please help...
Thanks
