Hi,

this might sound silly but I cannot find a schematic to do a simple adapter

I made this Y split cable, but I get an 'Unrecognized Device' in windows

although this seems done in accordance to usb pinout

USB-A gnd ------ USB-C gnd
USB-A D+ ------- USB-C D+
USB-A D- -------- USB-C D-
POWER 5V ------ USB-C 5V
POWER GND ---- USB-C gnd

any idea what could go wrong ?

thanks for helping me on this
