/**
 * Checks wether the specified device is a PS3 host. Weirdly enough, the PS3 reports 
 * a device class of 0x2c0108:
 *
 * Which means:
 *    - service (0x2c): Rendering | Capturing | Audio
 *    - major # (0x01): Computer
 *    - minor # (0x08): Server-class computer 
 * 
 * This setup seems rather generic for the ps3, however it will have to do for now. 
 * Another option, would be to check the bluetooth MAC prefix, which identifies the
 * adapter vendor. CECHGxx units seems to be built with Alps Co. adapters (00:1B:FB)
 * But to check it now could refrain this to work on other unchecked units.
 * 
 * So, currently we will only check for service/major/minor.
 * 
 * @param device
