I purchased a USB 3port miniHUB. It doesn't say that it supports USB 2.0.

Can I safely use it to connect USB 2.0 devices to a computer with USB 2.0
ports?

Thanks - next time I'll look more closely and be sure it's 2.0

If you can find a link for the mini hub or know the name of it. Post it
and I am sure someone will be able to tell if it is a 1.1 or 2.0 device.

It was only a couple of bucks so I assume it is 1.1.

I vaguely remember reading that some combinations of 2.0 and 1.1 could
damage one of the pieces of equipment, but I don't remember what combination
it was.

It sounds like you are saying that the only problem will be speed. If that's
so, I won't worry about it.

One other factor to consider. The USB 2.0 specification supports higher speeds
AND USB-powered devices. If you have a USB 2.0 device which takes its power
only from the USB port, odds are really good that it will not work at all.

There are a few very low power USB 1.1 devices whose power is supplied by the
USB port. The obvious ones are keyboard and mouse, but I also have a very nice
SanDisk USB 1.1 compact flash card reader/writer. It is plug-and-play with
either type of USB... Ben Myers

While we are talking about USB 2.0 can I ask a question? My Solo 9500 laptop
has two USB 1.1 ports and I am constantly reminded when using my CF card
reader that it would run faster on a 2.0 USB. I know I could use a PCMCIA
USB 2.0 hub (in fact I have one) but is there any way to upgrade the
internal dual 1.1's to 2.0? I have a wireless card in the other slot so my
PCMCIA slots are filled up. Thanks, Denzil.

USB 1.1 is a hardware limitation built into the motherboard of the system. If
it is inconvenient to use the PCMCIA USB 2.0 hub, continue using the CF card
reader/writer plugged into the USB 1.1 port. There is some difference in
performance, but it's not THAT astounding... Ben Myers
