Part Number:AM3352

Tool/software: Linux

Hi All,

We have BBB custom board and running with TI-SDK8, which has OTG port to connect mobile devices. The problem is when the USB mobile is connected to the board, the mobile is started charging,it's working fine and when we enable tethering, the usb is disconnecting and connecting back. Is there a possible way to not disconnect USB when the tethering is enabled.
