EVAL-HMC1023LP5 and HMC6356 USB Interface

Question

I have a EVAL-HMC1023LP5 and driving it with a HMC6356 USB interface card. This interface card appears slightly different them the one shown in the the photos 
 The usb interface card is using DLP2232H. https://www.dlpdesign.com/dlp2232h-ds-v11.pdf . 
 There does not appear to be a SPI output coming from this output header. Do you have a schematic for the HMC6356?

Hi Chris, 
 Sorry for the delay, I was waiting on an HMC1023 arriving to test this. I am addressing this over email with you, but I would also like to clarify here that the EKIT01-HMC1031, in terms of hardware, should work with either DLP2232H or DLP2232M versions of the HMC6356. Note that this was tested with the jumpers set on the DLP2232H as I mentioned previously. 
 I am actually not familiar with the LPF software so it is possible that up-to-date drivers are missing that another piece of HMC software I have installed does. 
 When I tested this I also had this HMC software installed on my PC:

 https://www.analog.com/en/design-center/evaluation-hardware-and-software/dual-chip-pll-evaluation-software.html 
 Or if you can source an older HMC6356 with the DLP-2232M this would clarify if the issue is with drivers or a faulty/damaged interface board. 
 if this does not work then I think there could be an issue with your HMC1023 board layout.
