AD9910 "Not Connected"

Dear ADI,

 

I am running a:

 

CentOS Host --> VirtualBox --> Win7 x64 VM

 

From the VM, I can select the appropriate USB connection (ADI Evaluation System) and I see a blinking green status LED on the board.  I have performed the HW mods to use the 25 MHz crystal:

 

Add:

 

R37 = 1K

C13 = 750pF

C15 = 25pF

R4 = R11 = 0

 

Remove:

 

C51, C52

 

The AD9910 Evaluation Software Version 2.1 shows a blinking "Not Connected" message in the lower left corner.

 

I have tried the W2 power up sequence mentioned in an earlier post.  What is the next step?

 

Thanks!

Kevin
