I’m working with a Colibri iMX6DL with WEC7 mounted on a Carrier board designed by us.
We have mounted a wifi module that connects via USB, sometimes when I start the Colibri I get the error “Unidentified USB Device: Exceed power limitation, USB device can´t be enumerated” and the wifi module does not work. What is the reason for this error? And how could I correct it?
On the carrier board we have a HUB, which connects via USB to the Colibri. From the HUB we use three outputs, one for a USB port, another for the wifi and one more for an FTDI.
