How could I decide whether I have USB 2.0 or 1.1 in WinXP?

[suyao]

Recently, I bought a notebook PC(Compaq Presario 2178AF). I installed
Windowsxp with SP2RC1. In the Device Manager, I could see only a "USB ROOT
HUB". But the seller told me that it go with USB 2.0 and some websites also
agree with it.
The problem is, how could I decide whether I have USB 2.0 or 1.1 in WinXP,
except for using a USB 2.0 device?
Thanks in advance!

In device manager, it will say Enhanced if you have USB 2.0.
If I cared I could go to the HP/Compaq website and look up
the specs.

Hello
If you have MS SP1 then when you look in the device manager under the USB it
will say Enhanced USB device

Post SP1 systems have USB 2 support. If the motherboard supports USB 2, you
can attach and use USB 2 devices.

In the device manager under USB, it should say USB enhanced 2.0 controller
or something to that effect. You have to have the 2.0 hardware built in for
it to be used.

Your notebook computer, (according to the specs on the HP site) says
it supports USB 2.0 devices. All you have to do is read your computer
manual, the specifications are listed there.

I have all USB2 controllers and devices (4 hard drives) and none of my
entries say Enhanced. And yes, they are working at 2.0 speeds.

I have the same series & SP1, and there is no proof I have found that
is has 2.0, nor does devman say "enhanced." You may never have seen
the 3rd-grade comic pamphlet (& CD) HP/Compac calls "a manual."
Nor could I get a rational (or even literate) answer from Compac.
"Supports" in the sales spec may be up for grabs as to exact meaning,
& after 5 months I'm still trying to find out 4 sure myself. IMHO the
OP's Q is not a frivolous one in this case with this box. I know that
my USB A/D, video & FD peripherals compatible with 1.1 & 2.0, well,
sort of run.

Is there a simple way to ID it 4 sure without relying on the mfg
published spec?

Look in Device Manager - USB section to see if there is a reference to
'Enhanced Host Controller' - the Enhanced indicates it is USB 2.0;
without that you have only USB 1.1 drivers installed.

The maker of the notebook (HP\Compaq) says it has USB 2.0 built in. I
don't know why you would need more proof than that. If what they have
written on their web site about the specifications is not true, then
it would be false advertising. HP\Compaq machines might not be the
greatest, but why would a large company like HP risk being sued over
false advertising?

The only sure way I know of checking is to actually measure the
transfer speed of a large file from the notebook's hard drive to an
external USB 2.0 hard drive using the USB port. Then compare the
speed with USB 1.1 and 2.0 specifications. Of course your mileage
here may vary, but it should reflect a ball park figure to determine
1.1 or 2.0 speeds.

Because it is wrong, and evidence is not proof. There is no enhanced
controller/driver on the box. Do you also believe that everything you
read is evidence?

AFAIK this is not a legal or ethical thread, nor even a mfg-specific
issue (don't you think those who can post to USENET can read their own
mfg's website?), but if you wish to sue them, please write us if you
get rich.

As I stated to you in the last reply (and you conveniently left out),
why not run your own benchmark and test to see whether your USB is
either 1.1 or 2.0? Since you doubt what HP has to say, obviously the
only way to convince yourself is to run a test.
