I am looking at a schematic for an IC that outputs to a micro USB connector. I am familiar with USB pins obviously having Vcc, Gnd, D+, D-, and an ID pin which can be grounded to distinguish host/slave device on micro connectors. However, I am not sure how to interpret this wire connection coming from the SIDE of the OUTPUT USB connector in this data sheet schematic. I don't think it is the ID pin because it does not run to GND. Does anybody have any idea what they mean by that side connection?

Thanks!

 

hi,
When S1 is set Closed,[for 100mSec] the ID pin #5, is connected to 0V via R13, also the ACT is enabled.

Thank you!!

 

Edit.

 

Really interesting since I'm having the same dilemma .. A Micro USB type B has 5 pins and there are many conflicting answers on the web .. What pisses me off is that neither Molex or Hiroshi map the pins in their specs .. so annoying trying to guess what is what .. I used my voltmeter to try and measure, but the plug is so tiny I find the Vcc pin .. I'm guessing pin 1 is Vcc and Pin 5 is ground ..
