complained the USB SSD wasn't working, and we pretty much agreed it was
bccause it used quite a bit of power and was plugged in a non-powered
hub (with 4 outputs, one of which was a USB Speaker)

So now I plug the USB SSD into the laptop directly and all is fine.

Well, tonight the external mouse stopped working. The laser didn't
light up and the cursor wouldn't move and the buttons did nothing.

Changing ports on the hub didn't help.

But Device Manager said it was working.

Boy is it incomvenient to work without a mouse. Some things are
impossible.

I dug up another mouse and the laser flashed when I turned on the switch
in the hub but then it went dark, exept one time that it stayed lit.
(this Dell mouse was something else. The scroll wheel was rotting,
making it hard to turn the wheel!)

Finally I thought about the hub and plugged the mouse into the laptop
direcly and all was well. Put back the original mouse.

But bear in mind I've used this hub at least since January 2021, and had
fcr most of this time had plugged in the mouse, the keyboard and the USB speakers, just as today, and all of it worked.

No one thinks a mouse uses a lot of current.

Could be Polyfuses or switches worn out.

You call it a hub but it could be something else.

So I went shopping for a replacement, and decided to watch the videos
for the one I was replacing.

10 short videos on Amazon!! and one pointed out that I can attach a
power adapter. There's a tiny hole with no markings that I never
noticed. And it's not mentioned on the box, and only 3 of the 10
mention it, and one of those because the version he was reviewing had an included power adapter, and the third was a different model. One guy
says he likes that it's not powered, and the video is so good I can see
the hole.

Maybe I'll find a power adapter and see if everything works with it

But bear in mind I've used this hub at least since January 2021, and had

Also, one of the video reviewers said his only lasted 2 years.

Another one says he's had it 5 years and runs 2 video led light panels
off it for the videos he makes.
C'est la vie.

And you were attempting to run drives off it ???

Well, the switches turn the light for each port on and off, but maybe
they are double pole and one pole is borken.

I guess the bridge article doesn't really help.

Has 20 videos. The same thing is sold with the power adapter included,
for $4.50 more: https://www.amazon.com/Sabrent-Individual-Switches-Included-HB-UMP3/dp/B00TPMEOYM/ref=asc_df_B00TPMEOYM/

It says "2.5 Amp Power Adapter Included to Power up Your Devices " and elsewhere says 17 watts, but doesn't say the voltage. Do you have a
guess?

If I divide 17 watts by 2.5 amps I get just under 7 volts. Is it that
simple? I don't have a 6.8v adapter and universal adapters are at
most 3V 4.5V 5V 6V 7.5V 9V 12V, but some have fewer. What voltage
should I use in a USB hub?

Right.

I'm 99% sure I DID run a small drive (2.5"), but like a dream disappears shortly after you wake up, this one is starting to disappear.

There's two ways to do the hub.

1) Use a 5V adapter and a relay to switch bus power.
2) Use a 7V adapter and a linear regulator which is one diode drop
above the desired VBUS value. The regulator has power limits, and
is unlikely to perform better than (1). If the linear regulator is
not an LDO, it needs even more voltage (and likely the tiny box gets
warm or hot too).

The Alcor schematic I was actually looking for, was the relay version.
The link I got above, is the diode drop trick, which is a bit sloppy
on voltage budgeting. It is the tight voltage spec, that causes the
hub designers some amount of grief.

You've probably had a fuse failure on yours. The question is, could the
fuse be edited out of the design, and would the design still work ?
For example, you could not get more than 2.5 amps from the wall adapter.
