Tried using srand with rand to achieve more randomness. sudo cat /dev/pico_rng | rngtest -c 1000 still says that it is not even close to being good enough. Although, if we feed this data into the kernel with the other data sources it should be FIPS 140-2 compliant. By itself it is not.

Driver exposes a character device /dev/pico_rng. Updated driver to support the character device. Tested with dd and cat. I am getting better performance than with Python, no shocker there.

Played around with usb kernel code. Ended up with these modifications that reads random data on probe.

Updated firware to contain only 1 endpoint. Created a global data buffer to hold the ADC EP1 IN data. This increased performance from 7.5 KBps to 150+ KBps.

Work in progress, updated test tool to only read and prototyped firmware to continuously write to the TX buffer. Firmware still needs work, this was only done to understand how the pico usb core works.
