Currently I take the assumption in the driver, that there is a tight

come with v1 API whilst new devices (U3Pro16 for now) support v2.
There is a sanity check during device scaning where the manufacturer
and product string is read out:
v1 has Product ID "USB-based Instrument"
v2 has "USB-based DSL Instrument v2"
If there is a mismatch the driver assumes that wrong firmware is
downloaded and triggeres a firmware download. So ideally you check the
Product ID before you launch pulseview or sigrok-cli. If legacy devices
now also come with v2, I need to update the driver to handle devices and
API version independently.
