I've had reliability problems with 4 different usb wi-fi adapters running Petalinux on my Cora board. I finally realized that the problem seems to be in the USB communications between the wifi device and the host. Occasionally, I see messages like this:
usb 1-1: new full-speed USB device number 4 using ci_hdrc
usb 1-1: device descriptor read/64, error -110
Any suggestions on how to debug? I don't have any experience debugging USB.
