Mouse is unknown device SOLVED

Hello All, I have a Lenovo laptop and although it has a key to turn off the touch pad it reverts back to touch pad use after a restart or fresh boot up so I went into mouse settings to switch off the touch pad when a mouse is connected. This has been working perfectly since obtaining the laptop in December of last year.  Twice in the last 2 days a panel has popped up saying that a recently connected usb device is unknown and not recognized by Windows. The only device connected is the mouse and upon receiving this message the mouse light goes out and becomes inoperable. Unplugging the mouse and inserting it again resolves the problem but I cannot understand why the problem occurs as it can happen after a few hours of use. The mouse is a standard one and did not come with a driver disk. Thanks for any info.

Hi, It seems that it is driver problem. Have you troubleshoot the issue, by going to the device manager, and right click the unknown device and then see whether there is any error message in it. If there is yellow exclamatory mark, then, update the driver by using the properties.
                                  If the problem is different, then will say some alternative

Hello jraju, yes I did check the Device section but only after I had reconnected the mouse and it said all is correct. If it happens again I will use the touch pad and check again but do not know if that will find anything wrong. I have W8.1 on this system. Thanks.

Hi, You mean to say that it hangs, the pointer never moves, and you loose the electricity connection. and rebooting solves the issue.
                      Could you say exactly what the problem is? Because, sudden stop of power to mouse, is to be considered as a annoying issue, for you cannot even move anything and you have to force power off the computer. If this is, then i will suggest , some registry tweak, that helped me to solve.
                 I tried update of drivers, manufa. drivers, etc. But , during hectic activity with slow speed opted pc, this issue is becoming increasingly annoyed.

When it occurs I just remove the mouse and plug it in again and it continues to work ok. The fault has only occurred once each day for the last two days.
