Hi all,

Am new to this forum and still a beginner in drawing schematics. I have come across this symbols from a USB schematics and would like to know what they are. I know the one on the extreme right is the USB connector and the ones with a lot of diodes is an ESD protection component (but I can't find out which one it is) and am confused about the ones on the left.

Any help would be appreciated.

Kind Regards,

Dev
