M.2 Accelerator B+M key

[jambamamba]

Description

I am trying to detect if my Edge TPU M.2 Accelerator B+M key is working or not.
I am using this board with 64 bit Linux running on the Pi4.

I built the libedgtpu and I am running my application with the library. I was debugging this function:
EdgeTpuManagerDirect::OpenDeviceInternal(
and it does not seem to detect any device.

How can I make the library detect the accelerator? I have been struggling with this for months, any help or direction will be appreciated!
