Hi,
We use upd720202 USB signals to connect a USB WIFI module (Sierra EM7455/7430).
This WIFI module could be detected but suddenly disappeared when browsing internet.
Then module will re-connect after few seconds.
We jump USB signals from WIFI module to CPU original USB port and it's works normal.
We also jump upd720202 USB signals to a USB connector and connect a USB stick and it works.
Please help clarify this what points we could check or the upd720202 image setting need to be correct
Thanks.
