For example, make chargers, earphone cables etc. This function is used to have schematics for making your own cables for customers. MSTAR cpu phones are difficult to achieve Read and Write on other boxes. Other box can't provide standing current over 30Ma for they only have one PCB panel. This function can be used to produce phone charger cable too.
Volcano's upper panel controls phone connector GND and VCC, which ensures phone to work normally and coordinate with box software analysis to detect charger-pin accurately. All these experience has been proved and tested over years. Firstly, there is no way to find out phone charger-pin secondly, even when you know charger-pin and set it to higher level, phone will directly reduce it because of heavy current, as a result, it fails to play the role of higher level as well as abnormal of phone detection/read/write operations.
When setting higher level to general SCM can only provide the current of 20 Ma. If you cannot find phone's charger-pin accurately and set VCC definition to it, phone will not respond to Read/Write operation at all. Because many phones can't work normally without GND and VCC, especially for MSTAR cpu phones. After years of practice we found out that box would have problems of no GND and VCC hardware design.
