SuzyQ / SuzyQableSuzyQ is a cable that tells the Cr50 to go into debug mode. SuzyQ includes a USB hub in the cable, which allows the host computer to access both the debug interface (on the SBU pins) and any gadget-mode interfaces exposed by the device-under-test (for example an ADB interface for debugging Android applications).
