I tested with en usb wall charger, that i had at home.
And it didn’t work, it was charging but not able to listen music.
But there is an easy solution, I explain to those who have the same problem.
I just modified my wall adapter. In reality an usb link has 4 connectors :
And when electric current passes through the D- and D+ connector (on the middle, used for data),
The player thinks that he is connect to a computer, so it changes his mode, and listen music is impossible.
So, on my wall adapter, there is an USB female connector, and when i removed this 2 connector (D- D+), player
doesn’t recognize data. So it plays music because of the only two electric current connector :stuck_out_tongue:
It’s strange that there is electric current on this two connector (D+ D-) because when it’s connect to the wall,
we doesn’t send/receive data… but i don’t care cause now it works !!
Thank you for your help!
