Question on ISR USB over-current

[Jagan1976]

Hi guys,

I am seeing this error below once in a while on my ISR4451 router. 

Anyone know what is the cause. Tried to google but could not find much info.

Thanks.

Do you have any USB devices connected? what size of the USB? if you remove the USB you still see the Errors?

show version 

dir will help us to understand the issue?

No, nothing connected. If I connect something, it works ok.
