The issue has been discussed in several threads, for example

Basically due to some loose innards connecting an internal USB device in the laptop, you hear the USB connect / reconnect sound randomly and it can get quite annoying
I've encountered this phenomena with a Dell Inspiron 1520, where the USB camera would do this constantly. It was easy to tell since the camera light / indicator flashed each time it did, but in other situations it might not be trivial to tell which device is the culprit
Also, you'd think disabling the defective device in the device manager would stop the annoyance - well, in my case, it didn't
Fortunately, Nir Sofer comes to the rescue (as he does many, many times - you should really check out his site):
- Download USBDeview and run it
- Sort the list by the "last plug/unplug date" column (is this guy a genius or what) - the problematic device is immediately identified
- Right click on it and choose "disconnect selected devices"
You're done. Until you get the hardware fixed (if ever), you are no longer plagued by that infernal sound. I'm not sure if the disabling persists reboots (haven't rebooted yet), but if not, USBDeview has a command line interface - so you can place a simple shortcut in your startup to disable the device every time the system starts
@Mods- I wasn't sure whether this was the right forum to post this, feel free to relocate it if not
Peace
Easy workaround for the USB random connect / diconnect / reconnect issue
