Hi Folks!

Have been connecting my USB keyboard and mouse to a powered USB 2.0 hub
just because don't need extensions. Works fine, except when I do
something stupid a lock up the computer it seems the keyboard won't
work: has power, or at least the NumLock LED is on.

Theoretically I'm supposed to do ALT_SysRq_REISUB to evoke a reboot
(it's a Linux system) but rarely will that work. OTOH it rarely worked
when I had the mouse and keyboard plugged in directly to the back panel.

So, any advantages/disavantages over plugging the mouse and keyboard
directly into the back panel over via a (powered) hub?

TIA!

My Keyboard is plugged into a PS/2 Jack on the back of this XP pc.

I used a Cordless Mouse for a while but still kept the Wired Mouse
plugged in the Jack on the back that's next to the Keyboard Jack in case
the battery ran down on the Cordless Mouse.

I'm using the PS/2 Mouse now, can't remember why I retired the Cordless
Mouse.

That would tend to make it difficult to plug into a USB Hub! <gg>

I've found some older computers (really the motherboards) require a
keyboard and/or mouse to be connected to their PS/2 ports else won't
complete the boot process. Some of the BIOSs have an option to go
without a keyboard -- I've never dared as if something goes wrong how do
I access then?? Could go inside and use the BIOS Reset jumper but that
undoes all the other BIOS settings too. So if a wireless keyboard (and
mouse) is needed I just plug the wired ones in and prop next to the
computer.

I'm using the PS/2 Mouse now, can't remember why I retired the
Cordless Mouse.

Battery died and didn't have one available?

Sure would. Round Plug can't fit in a Rectangle shaped hole.

I have two powered usb hubs on this XP box and one powered usb hub on a
Vista notebook.

Being picky I'd rather have a A.C. Powered USB Hub in case I had several
things plugged into the Hub and some of them wouldn't work because the
Current being robbed by others devices connected in the same Hub.

You're picky about USB Hubs too, I see.

This HP XP box was bought in 2006, it hasn't showed it cared if a PS/2
Mouse or USB Cordless Mouse was the only Mouse connected when I turned
it On.

I'm using the PS/2 Mouse now, can't remember why I retired the
Cordless Mouse.

I put a battery in it to test it and noticed the LED blinking, I may have retired it because it wasn't behaving as it should.

The USB Plug for the Mouse is taped to it, I didn't try using the Mouse.
Seeing the LED flashing causes me to 'think' it would be a waste of time
taking the tape off, plugging the Receiver in and having to tape it to the Mouse again.

I was wondering if the BBS You use has more Networks than IL Net
and Fido Net?

We;, if you really-really-REALLLLLY try!! Or could cheat and use an
adapter.

several things plugged into the Hub and some of them wouldn't
work because the Current being robbed by others devices connected

I've had some quirky things occur over the decades so try to get good
quality. One USB 2 powered hub I'd swear is running at 1 (or 1.1): the
label on the underside says "USB 2.0" but everything I had plugged in to
it ran slow. Kept it only because it was good as a spare: slow is
better than none should I for some reason managed to fry a hub. Will
probably toss it (will, electronics recycling) now that I'm upgrading to
USB 3.0 and the USB 2.0 hubs will go at the end of the runs if necessary
to boost the signal for a USB 2.0 device.

I used a Cordless Mouse for a while but still kept the Wired
Mouse plugged in the Jack on the back that's next to the Keyboard
Jack in case the battery ran down on the Cordless Mouse.

Good idea. Just make sure the spare mouse doesn't pick up vibrations

could see a hyperactive dust bunny activating the spare mouse's

pickup!!

HP seemed to be one of the more advanced manufacturers.

(That sneaky little dust bunny!!)

I have a few wireless keyboards (and mice) around the house for the
Mythbuntu Frontends: frequently easier to go wireless than run a few
extension cables along the wall. One of the originals is IR, so have to
point the invisible beam from the keyboard to the pickup on the
computer. In the Family Room didn't work all that well; swapped with
the wireless keyboard and mouse in the Sitting Room (other houses would
be a Den) and worked fine -- probably a combination of a little less
distance and positioning.

The USB Plug for the Mouse is taped to it, I didn't try using the
Mouse. Seeing the LED flashing causes me to 'think' it would be a
waste of time taking the tape off, plugging the Receiver in and
having to tape it to the Mouse again.

Umm, sometimes the tape's adhesive dries out and need new anyway!

Nope; just ILink.
