Failed to claim USB interface: Device or resource busy (error 16) under Ubuntu

Having multiple boards connected simultaneously and trying to run a single instance of our software with each board (using the serial number to associate the proper board) we are seeing the “Failed to claim USB interface: Device or resource busy (error 16)” error under Ubuntu. This does not happen under Windows in the same configuration.

Any idea what could cause this error? We are on Linux-5.3.18-22-default-x86_64-with-glibc2.17 (Ubuntu).

Cheers,
Thomas
