I came across these after watching a Linus Tech Tips video on a Panasonic Toughbook. It had a Fischer connector to accept the linked flash drives. I thought it was interesting to see a circular USB connector that had become standard enough to be included on a professional/semi-consumer grade laptop. I'm not in any way affiliated with Fischer — just thought it was cool tech.
