Hi
I've a problem with spam in syslog.
Every fraction of second I get
Code: Select all
usb 1-1-port2: over-current change
Is there any way to ignore this? Maybe disable over-current warning, or logging msg that are not warning at least?
I've been googling around, but haven't found anything.

I would start by trying to solve the power problem instead of ignoring it...

Which model of Pi?
What is connected to the USB ports?
What PSU?
Likely not relevant, but what OS?

Model: Pi 2 B+
On this port is a USB HDD (WD Red in powered Natec RHINO case)
There is also RPi Wi-Fi dongle on other port.
OS is Raspbian
Pi (and Pi Display) are connected to
http://www.ikea.com/gb/en/catalog/products/70280993/ (display and Pi are powered separately, but connected through pins)
When I use this disk "more" (open some video file through samba, etc.) those messages usually stops

Have you set the higher current limit for the USB ports? To do so,
add "max_usb_current=1" to config.txt

I've already tried this. There was no difference.

Disconnect both USB peripherals. Does that stop the message? Reconnect one at a time to determine whether one peripheral is responsible, or whether it is just the total load of all USB peripherals that causes it.

Looks like it's neither nor
When I disconnect Wi-Fi dongle I still get message flood in log.
Disconnecting USB HDD stops it. So it looks like it's HDDs fault.
But when I reconnect HDD (with plugged Wi-Fi dongle) there is no over-current message. At least for now.
I'll check if it comes back (maybe there are somewhere power settings? like hdd sleep?)

over 30 minutes and still no over-current warning...

Hm... Maybe this is similar case to
viewtopic.php?p=997498#p997498 ?
I'll try it out later
