picozed SDR development kit startup problem

Question

I am trying to bring up a picozed SDR development kit for the first time. I believe that I've follow the instructions well. When powering up, my HDMI display shows signs of life and it sometimes displays a few windows for about 5 seconds but then goes blank and remains in that state. When trying to bring it up, the HDMI display often just stays blank. Any help is greatly appreciated.

Problem solved The problem is that the PicoZed SDR Development Kit comes with the wrong cable for the USB hub and the documentation (PicoZed SDR Development Kit Getting Started Guide v1.4_0.pdf) likewise guides the user to do something that cannot work. The kit comes with a micro-USB to USB type A, MALE connector (this does not work since it ostensibly treats the development kit as another peripheral bit it is actually a host). The solution is to treat the development kit as a host, using a cable with micro-USB to USB type A, FEMALE . This female connector attaches to the USB’s singular host connector and all will work fine. Here is an example of such a cable for $4.99. https://www.amazon.com/OKRAY-Braided-Adapter-Samsung-Function/dp/B01G81GY7M/ref=pd_sim_421_11?_encoding=UTF8&psc=1&refRID=2N0SJJ7QC3TZ59RQ6KTN Avnet should correct all of their PicoZed SDR Development Kits and the associated documentation.
