In AR9331, connect-debounce failed and port 1 disabled are displayed.

This error occurs on the PCB Board of the Router Based on AR9331. In Baidu, it seems that many people have encountered this error, but before I modify the board, I use the firmware, and the USB is perfect.

This problem occurs after the Board is modified!

The background serial port keeps reporting this error.


The USB data line is reversed. Haha, try the Jumper in turn!

It's okay to identify the USB flash drive!

Forget it!

What system are you using? SUSE or UBUNTU? SUSE seems to be a common problem, and there is a bug explanation on the official website. If iptables is in UBUNTU, is port2 disabled?
