Re: [SOLVED] USB port error

What makes you think it's an error? What problems are you experiencing? What research have you done into this message?

Re: [SOLVED] USB port error

You don't solve error messages.  You solve problems.  You use error messages to help identify the source of a problem that you want to solve.

Is there a problem you want to solve?  If so, what is it?

Re: [SOLVED] USB port error

That message means that the controller is seeing "signals" on the USB bus that appear to be noise rather than anything recognizable as a USB device.  And that it is now going to ignore them rather than try to interpret them.
EMI means electromagnetic interference.  The suggestion being that a source of electrical noise nearby may be upsetting that port. It is not necessarily the case.

Have you anything connected to that port?  Are you using good cables?  Do they meet all of the USB specifications, including maximum length?  Is there a transmitter (like a wireless access point or a portable phone) sitting next to that port?

There is no problem at least I didn't see any. I just want to solve this error, this message is shown on each boot.

Did you in /etc/modprobe.d/options add the following

options dvb-usb-dib0700 force_lna_activation=1
