Is there an easy method of establishing if the USB ports on a PC are USB 2.0
or just 1.1
Thanks

In Device Manager {Right click on My Computer, select Properties, Hardware
tab and click on Device Manager} under Universal Bus Controllers you will
have an entry for a Enhanced Host Controller if you have USB 2. If no such
entry, you have USB 1.1.

Don's right, but don't misread him. If you have one Enhanced and
several non-enhanced, it's still quite possible for all the physical
ports to be USB 2.

Strange thing that. On my system (with Intel southbridge) my 6 USB
ports show up as 3 "Standard USB controllers" (2 USB 1.1 each) AND at
the same time as 1 "Enhanced USB controller" (6 USB 2.0 ports).

But it's only 6 physical ports. Can anyone explain this odd behaviour

Adding to Don's response; you can add USB 2.0 with an inexpensive PCI card.

I did that just recently. Only cost a few dollars and 10 or so minutes
& the difference is very noticeable.

Can I add my 2 bits worth here in case it helps someone? I have just had a
frustrating experience with a new Canon MP Pixma series printer not working
with a PCI USB2 card. The printhead on my old Canon printer failede and
rather purchase a new printhead I purchased a new printer. I had nothing
but trouble with the printer not responding when given a print job or it
would start and stop midway through and just sit there showing print job in
progress. The latest printer software updates made no difference and it was
not until I did some extensive digging on Canon's tech support site did I
read in an obscure column at the bottom of a page that the printer is not
compatible with an add on USB card and must be supported by USB2 from the
motherboard.

The USB bridge allows one enhanced controller to enable USB 2 support for
all ports.

I've got a similar thing on my Acer laptop, and I challenged the
company about it last year. As I say, the number of ports showing in
Device Mangler doesn't necessarily match the actual physical number
of ports. I have only one "Enhanced" showing, but by connecting a USB
2 device to all three physical ports I verified that all three were
USB 2.

I suspect that the "Enhanced" can control all the ports, or all up to
a certain number, but I never checked that out.

And now I don't have to -- Larry Samuels' article confirms my guess.

Working with high speed scanners (we talk 100 sheets/second scanners)
we tried to move from SCSI til USB2 during the last norwegian
election. And we found that USB2 have very different compability.

On board Intel USB2 controllers always worked OK, so did add-on cards
from Adaptec. But several other USB2 cards did NOT work at high speed.
as soon as the scanners started to scan full speed all locked up :-(

He he, that should be 100 sheets/minute of course (6000 sheets/hour)
