[Solved] USB Over-current condition on port 3 and 4

Hello everyone,
I finally booted up arch from my HD, however the problems doesn't end (welcome to arch for me)
And arch greeted me with the following message:(may not be exacly the same):

Fast TSC callibration failed.
usb-0.0.0.0(do not remember numbers) Over-current condition on port 3
usb-0.0.0.0(do not remember numbers) Over-current condition on port 4

Then I logged it, startx and everything seem to work fine for now.
However the message is bugging me.

Can you please help me(or at least show me the way) to fix this.
NOTE: I've got linux mint 14 installed and it doesn't seem to have such problems.

NOTE2: this is what I got from lsusb -v: (from arch)
http://pastebin.com/FNLVeufn (line 141,142)

NOTE3: lsusb -v (from mint)
http://pastebin.com/XJwA0L2a

P.S. Actually I've got the feeling that arch is just printing this without a real problem?!?!

P.S.2: This is laptop Asus-K53SV. Thus all usbs that are visible are working(I've got 2x 2.0 usbs and 1x 3.0)

That message can hint to a broken / defective usb-port. Maybe you have two front-usb slots registered as port 3 and port 4? I've seen broken front-usb slots before, but this is just a guess. Try disconnecting them from the motherboard.

For everyone with laptop ASUS (K53 and others also):

For some reason linux thinks that there is over-current condition on port 3 and 4.
This is probably a false alarm. Nothing to worry about.

After changing different versions of the kernels and trying on different machines the result was that all laptops K53(there are many ppl with this laptop around me) gives positive result(overcurrent), tough the message is hidden by default on some versions of the kernel(with dmesg it's still there).\

Marking as solved.

Even I have Asus K53SM laptop and I can confirm the issue. As noted here, I hope that this is just a warning and will not cause any problems!

I can confirm that this error message has been present ever since I got my K53SC back in 2011. Nothing to worry about, I'd rather call this a false alarm, because none of the connected devices (cameras, smartphones, pendrives, external drives, portable mp3 players) were damaged over the years. By the way, these over-current condition warnings are related to the USB 2.0 ports, not the one USB 3.0.

Re: [Solved] USB Over-current condition on port 3 and 4

It really means that your device is drawing more current from the port than it negotiated for.  On a USB port, a device is not permitted to draw more than 100mA at the time it is connected to the host.  During discovery, the device tells the host how much current it requires for full operation.  The host can then authorize the device to draw that much current, or not -- based on how much current is available.  On USB 2.0 the maximum permitted draw is 500mA, but only after negotiation.   Your device is ignoring the current limitations and your host is protesting.  USB 3.0 permits 150mA initially, and 900mA max unless it supports the newer battery charger extensions, in which case one can draw up to 1800mA after negotiation.

Hello everyone,

I also have a laptop with the same problem - Asus K53SC => over current condition on port . . .
I get this message even if I disable the USB ports from BIOS and I know there is no real issue with the ports.

Please tell me how to get pass this message and log into the system. Do I have to load the kernel manually? And if so, how do I do that?

Thanks in advance!
