It seems that I was wrong: USB2 driver seems to be working well, at least for the first
configuration steps, because I am successful in configuring the Cypress FX2.
Then it looks like the problem is actually
in the next step, that is, loading the fpga bitstream /usr/local/hamradio/gnuradio/share/usrp/rev4/std_2rxhb_2tx.

In my experience, a successful FX2 load followed by a failed FPGA load
is often due to poor USB physical integrity, such as a cable, connector,
or hub. I know it sounds formulaic, but for whatever reason, I’ve
encountered this with the USRP on multiple occasions, where replacing
the cable with a different one, ensuring that has the 2.0 compliance
logo on it, fixes it. YMMV, of course.

Well, I’m using the cable shipped with the USRP.
It is out-of-the-wrapper new and shows a shiny USB2 logo.
But, yes, I’ll try changing the cable and the USB connector, as I’m not
using any external hub.
What about my questions?
- What can I use to trace/debug/investigate the final fpga load
operation? - Where is the source code of the program performing the actual fpga
load? - What does it mean that led D402 turns on during this (test)?
Thanks so much.
