Thunderbolt - Forcing Scan & mounting of eGPU

[LinuxGuy1997]

I cannot see any reason why they machine will start seeing the connection, therefore I wonder if there is a way to force a scan and push the connection.

My apologies, also meant to reply to this part specifically.
You can try forcing a PCI bus rescan by running this as root:

# echo 1 > /sys/bus/pci/rescan 

Hope this helps!
