Re: USB connector failures?

[Jonathan Newman]

I'm sure whatever wear you might get could be countered by buying a new 
plug to go into the socket. since USB relies on a dual push self 
cleaning contact if the socket's springiness gets weaker you'll find 
the same thing will be happening to your mouse's plug. So if you buy a 
new mouse you'll gain that feeling for some time, and buy you some 
time. The only other failure with USB could be casing problems. if the 
socket's casing gets out of whack you'll find the USB will feel loose, 
it may even cause a joint solder problem too. But usually USB doesn't 
get used enough to really have a problem. What I mean by used enough 
is: plugging, and unplugging constantly, for a half a year, I think you 
could wear it out.

I have a G3 iBook, which see a lot insertion
and deinsertion (removal) of either a mouse
or on the other side a connector to a 7 port USB Hub.
Sometimes the laptop needs to go to another location,
 so the conenctors get pulled
the laptop closed and off I go.
Have found I simply don't like any so-called mousepad on any laptop;
the ole roller ball would be the best but then...
So I usually have a small MaCally mouse, which gets plugged into the 
USB
connector,
then unplugged when the computer gets move again, usually the same day.

Of late have found the insertion of the male connectors doesn't always
fit just so,
resulting in a failure to electrically make contact.
The USB is a wonderful device however would expect failures at some 
point,
more from a wear factor on the actual contacts.

Anybody else?
