Hi,
In my board,USB0 is used as a host,and USB1 is used as a device.Board-A's USB0 is connected to Board-B's USB1,and,Board-B's USB0 is connected to Board-A's USB1.
| Board-A | USB0(host) | --DP,DN--- | USB1(dev) | |
| USB1(dev) | --DP,DN--- | USB0(host) | Board-B |
The USB1(dev) power is provided by itself board, not the connected host board，which connected the two board is only DP,DN pins,ESD using a TPD4S012.
When I do a hot plug,unfortunately，the two board are all damaged,the CPU can not work any more.
Can anyone help me ?
Thanks
