USB hub dong ding

[JimL]

When I turn on various USB devices such as my external hard drive or printer
I get a dong ding sound. When I turn it off I get the ding dong sound.

Why should I get a dong ding sound when I merely plug in a new hub? No hub
I've ever had before did that.

Thanks

DING DONG is usb"speak" for "device change detected"

DING DONG is usb"speak" for "device change detected"

Obviously, but as I said this is the first time I ever just had a hub
"speak" with nothing plugged into it. From their previous silence I assumed
the hubs themselves weren't actually considered "devices" in that sense.

Back to my question. Why should I get a [dong ding, speak, change notice]
when I merely plug in a new hub? Or should every one I had before have done
it?

Thanks

It might be interesting to identify why you haven't observed this before,
but it is normal behaviour.

Hm. Actually I probably haven't plugged or unplugged it while the laptop
was on, come to think about it.

Thanks

LOL!

Not funny at all. Avon never says dong ding!

Or you had the volume turned down.

Interesting that you would note that. As a matter of fact many (or all?)
T42's have the "volume turned down" permenantly. Watching news videos, for
instance, requires extension speakers unless you have very good hearing.
Other T42 owners have noted this lack of volume from the internal speakers.

Thanks

Try a different driver, and muck around in the registry
looking for output level numbers as a few, not necessarily
all, audio devices can have their levels changed with manual
registry editing.

Then again they might've just used cheap speakers that can't
tolerate high output, sometimes it's pretty amazing the tiny
speakers do as well as they do.

My old ThinkPad 770E could almost blast you out of the room with its tiny
speakers.

The T42 is a 5 year old+ business-oriented laptop and, as such doesn't
really 'do' multimedia. They have two 1 watt speakers at the front edge
facing down and the sound is supposed to be reflected back from the desk.

As mentioned, they are notorious for being very quiet. About only any good
for hearing system sounds. Thankfully they fixed the problem for my current
main laptop (T60) and the speakers are loud enough to watch a movie,
although obviously lacking bass. Oddly they're rated at 1 watt also. It must
be a sensitivity thing.
