> Issue Type: Bug
> Security Level: Public(Viewable by anyone)
> Reporter: Marko Kiiskila
>
> I have 2 test i2c devices. I can do 'i2c_scan' on either, but will discover
> the device only once.
> On subsequent runs the device does not report being present. Should
> investigate if this is because a) the device itself refuses to respond or b)
> hal i2c driver on SAMD21 is faulty.
