I asume they are unrelated from a logical standpoint, but I don't know bluetooth technology. We have a similar situation with ulpt, where we usually have up to three interfaces with different capabilities. ulpt currently pics one of them, but we could also have three different ulpt instances taking each one of them. Well the AC88172 PDF is very clear about having 2 interfaces. The document also speaks about 4 endpoints, which I expect to be on interface 0 as they also have listed endpoint number 0 - they don't tell in the document. What I currently don't know is why there are 2 interfaces. The document also mentions some homenet capabilities on RJ11 - whatever it means. Maybe it's an hardware optional interface, which is disabled in this special device. For the ID strings - it seems that the hardware vendor just left the string empty in the eeprom. -- B.Walter BWCT http://www.bwct.de ticso@bwct.de info@bwct.de
