Error Code 38 reconnecting USB Mouse in Win7

Microsoft Windows 7 home premium

Specs: Windows 7

I'm using a Microsoft USB mouse with my
Win7 Home Premium. Everything was OK
since I bought the laptop in December.
However recently, when I plug off the mouse
from the laptop and plug it back again,
Windows doesn't recognize the mouse. I
checked the device manager and apparently
it's happening due to Code 38 (driver is already
in the memory). When I restart Windows the
problem gets resolved but as you may guess
re-starting the windows each time you plug off
the mouse is annoying. The problem doesn't
happen when I e.g. plug-off another USB
device such as an external hard drive. I don't
think there's any problem with the mouse as it
works normally on other laptops. The thing
that concerns me is I was having the exact
same problem with my previous Dell laptop
running on Vista 64bit and similarly it wasn't
happening when I first bought that laptop but
started some time later. I'm suspicious of
some software that I installed may have
caused the problem but I can't figure out what.
I'm regularly updating the device drivers for my
VAIO but not sure if they may have caused
anything either. The thing is, it wasn't there
before (similar to my DELL) and it started
happening recently and it gets solved when I
restart the laptop. Isn't there a way to ensure
the driver is deleted from memory every time
you plug it off so that you can plug it back in
again without any problems?

I plug off the mouse from the laptop and plug it back again

Why do you do this? USB mouses are never designed to be disconnect and reconnect while the computer is running. It can cause Windows to fail since there is no Safely Remove Hardware trigger switch.

By the way for an explanation of Error code 38 generated by Windows Device manager, read M$ knowledgebase article HERE (while it is written for Windows XP, the code also applies to Windows 7).

well...don't you ever plug the mouse off e.g. when you'll take
the laptop on your laps and use the touchpad as otherwise
you'll need to deal with the cable of the mouse,etc...:) it may
be technically incorrect but in practice i've never had any such
problem at all with any of my laptops during the past 10 i was thinking it may have a proper explanation and
solution other than saying "don't plug it off" or "restart the
computer to solve the problem"

can anyone help with this? is it really uncommon for people to
disconnect mouse and re-connect?? even if it's so why do you
think the problem was not happening before and started
happening recently?
