While testing U2IF I've noticed that it sometimes takes more than one try to connect to the device:
>>> dev = machine.Device()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/mnt/projects/u2if/.env/lib/python3.7/site-packages/source/machine/helper.py", line 9, in __call__
cls._instances[cls] = super(Singleton, cls).__call__(*args, **kwargs)
File "/mnt/projects/u2if/.env/lib/python3.7/site-packages/source/machine/u2if.py", line 22, in __init__
raise ValueError("No board found")
ValueError: No board found

In the example above it took 3 attempts to connect to a RP2040 Pico. Given that the hid library seems to only return null/None with no apparent errors thrown would it be possible to add some kind of connection retry mechanism?
