why is the usb connection and disconnection sound repeating over and over?

[longshinshen]

recently my computer constantly usb connection and disconnection sound.
every time I connected to the internet and the web, it constantly emits sound.
Meanwhile, the mouse always is jerky.
Occasionally, the mouse is disconnected with usb port.
when I'm not connected to the internet, it does not appear? (turn off device)
before now I had never encountered this situation.
help me!

Laptop ? ?

Sounds to me that the USB port the mouse is plugged into is broken...
It can be repaired at a shop.

For the time being try the mouse on another port. If it still does this then there's a short in the mouse cable...

Additionally if they have a USB HUB with a bunch of stuff connected to it, they could be borderline exceeding the power capability for the port causing it to disconnect/reconnect USB

Good point...

sorry! Now I will tell... 
it's desktop and can connect to the Internet using Wi-Fi modem.
I often open wifi to use for android.
thereby connecting with the usb signals appear every time I connect to the internet.
as has the background to do something that conflicts with mouse driver. (my think)
but now it do not appear ?! 
since that time now I do not have to do anything ?!
Maybe my computer has been compromised ?!
I use norton security.

but now it do not appear ?! 
since that time now I do not have to do anything ?!

Does this mean the problem has gone dormant, not happening anymore?

[longshinshen]

it does not emit the cry for a few days before.
but today again!
can someone help me how to check the possibility of unauthorized access to my pc on the internet?
it shows when it connected online (internet)
offline, it does not appear ?!

It has nothing to do with your system being compromised.

It's probably your cell phone connecting and disconnecting. If it doesn't happen when your cell phone isn't connected, that's almost certainly what it is.

On top of that i've never seen wifi use the USB sound signal each time it connects...so that's not it either.
As i suspected above 1 of your USB devices is loose and/or a USB slot has been loosened to the point of causing what you see...

[Allan]

I've seen this a lot with some Android phones. They can't maintain a constant usb connection and you'll hear the usb sound every time the lose and regain the connection - especially early on in the session.

Thanx for the clarification...i unlike Luke own no Droids so i wouldn't have known this...

 

[Allan]

And when all is said and done, that may not be the problem - but I'm guessing it is

True dat...

hi!
I only connect to wifi for internet (only pc, Do not use anything).
now, it still appears ?! (a bit)
add one more thing my web browser is not able to run the default search bar (firefox).
if you set any specific tools such as Yahoo, bing ... as the default search engine, it can not run.
I felt something was running when I connected to the internet?
Probably because of something that runs in the background, it conflicts with the driver of the mouse. (i think)
can someone help me?
(i checked by norton sercurity,iobit malware fighter... nothing?!)

I suggest you visit the Malware removal section...follow the guide and post your logs...

Iobit is junk and i've never heard of malware fighter.
