USB Over-Current Condition

Post by jkeogh »

Hello,
When booting in Linux Mint, I see these messages appear:

usb usb8-port1: over-current condition
usb usb8-port2: over-current condition
usb usb9-port1: over-current condition
usb usb9-port2: over-current condition

Is this a problem with the hardware?
Or is it just a warning?

What is connected to these ports?
USB_VBUS capable to deliver up to 2.1A to the dual port, meaning 1.05A max if two bus powered devices used or 2.1A if one.

So it is pretty complicated to overload the port.

I believe ports 8 & 9 are the rear ones and I have nothing connected to them.
The only port in use is at the front with a Logitech wireless keyboard USB Key.

This situation may happen just on USB3 ports and just in Linux in older board revision. This happens on insertion so after insertion port should work fine (somehow in Linux the reporting is staying continuous).

Ok, I'll just ignore the message from now on.
Thanks for the info.
