Hello ALL,
I am facing problem with usb OTG connection The below are the
details for the same
The modem is disconnecting after is boot is done some times it is
reconnecting immediately and sometimes its not, some times the modem is not
detecting at the boot time but I am observing the modem is *ON *throughout
this procedure.
As per our analysis the modem is dis connecting in function
hub_port_connect_change() *which is in file*
drivers/usb/core/hub.c
*The part of the function where it is failing is *
if (udev)
usb_disconnect(&hdev->children[port1-1]);
As the modem is disconnecting in the middle the ttyACM ports are getting
lost and the signal on UI is going and RIL-execution is stopping
Can anybody tell me what might be the problem
Kindly refer the logs at

Thanks & Regards
O S L Reddy
