USB2 v/s USB in XP - help?

OS is XP SP2 fully up-to-date. Motherboard has USB on-board, 2 front, 2
rear. Processor is Athlon 1.533Ghz, 760 mb RAM

PROBLEM - just installed USB2 PCI card, which appears to work (adding 2 USB2
ports to the rear). Also bought USB2 4 port hub, to allow flexible
connectivity.
Initially, rear ports on card worked, but connecting the hub to one of
these, and a USB2 memory stick into the hub, resulted in the "this will work
faster in USB2" message. Tried the MS download site for updated driver
(zilch), but by some miracle, after two re-boots, system now appears to be
working correctly (meaning - no more "this will work faster" message).
Installation CD had text file saying MS SP1 had appropriate drivers - not to
use the CD for XP.

As a test, I copyied a 120mb file in both USB and USB2 mode. There's
virtually no difference in the transfer time (about 3 minutes). I thought
the whole point of USB2 was that it was 10 times quicker. I now have 4 USB
ports on the motherboard

Am I missing something? What should the transfer time be for 120mb in USB
and USB2? Reason for the question is that I don't know whether USB2 is
actually working (if so, why are USB ports apparently working at same
speed?)

Use a program such as EVEREST from www.lavalys.com to
identify the exact make/model of the motherboard. Get the
mobo manual to determine any special requirements of the USB
built-in the mobo. You want to know if any of the ports are
shared.

Also, use the device manager to remove ALL USB ports and
hubs and then reboot. The system should identify all the
ports and the new card as "new" and install the best
drivers. With SP2 installed, you should then have USB 2.0.
BTW USB 1.1 is ten times faster than 1.0, USB 2.0 is 40
times faster than 1.1 (480 mbps).

To repair the message: "this will work faster in USB2...", we remove all
root USB hubs and controller from Device Manager. Then after XP reboot, it
should correctly re-install the USB controllers/root hubs (include the USB2
controller/hubs.)


Have you check with your motherboard manufacturer to see which USB standard
the on-board USB ports are? They could be USB2 compatible already and that
is why you can not compare the speed since you do not have USB1.1/1.0 ports.

First, you need to remember, USB speed refers to throughput not write speed.
Second, some devices don't work or work well off of a USB hub. Have you
tried connecting the device directly to the USB2 port as opposed to the hub
connected to the port to see if there is any difference and whether or not
you receive the same message?

120 MB in 3 minutes is a little more than 5 Mb/s. That's not close to the
maximum USB 1.1 throughput and even with a lot of overhead, there would be
some room to do better.

What memory stick is it (brand/model)? Have you tried to copy the file back
to your main disk and benchmarking that instead? My reason for asking is
that a lot of sticks give far better performance for reading than writing. I
doubt it a bit, but maybe you'll see a performance difference in that
direction.

Actually, based upon our experience, a data transfer rate of 40 MB/min,
i.e., 120 MB in three minutes, is just about right in real-life terms for
USB 1.1. I've rarely seen data transfer rates greater than 50 MB/min in a
USB 1.1 environment. Using USB 2.0 your data transfer rate should be
somewhere above 450 MB/min. So it certainly appears that you're working at
USB 1.1 speeds.

Carl, Art - I think I've solved the problem now, and to answer your specific
points re speeds - there's a significant difference now (but not 10 times)
between writing a 117 mb file from C: to memory stick using USB2 port -
about a minute, versus just over 3 mins.
However, the write BACK (mem stick to HDD) is about 15 secs in USB2, about 1
minute in USB1.
Many thanks for your advice and info - Sincerely, Len.

Yves, Jim - whilst following your recommendation to uninstall all USB's I
caused havoc - realised too late that my radio mouse/keyboard relied on USB
connectivity (radio controller). Havoc !!
I should perhaps say that my 3 year old ASUS motherboard is only equipped
with USB (not USB2) which is why I bought the USB2 PCI card and extension
hub in the first place ...

OK - bottom line is (qualified) SUCCESS ! Having connected PS2-style
keyboard and mouse, I uninstalled all USB devices, re-booted, and they
configured. Have now re-tested the memory stick both ways, using a 114Mb
file to/from the HDD, and USB2 functionality/speed is noticeable - about
1.30 to upload, 15 secs to download it to HDD.

MAJOR DRAWBACK - my Logitech (USB) radio receiver is now a problem - Device
Manager reports drive missing/corrupt, and cannot find a new driver - none
on Logitech site. Everything was OK this morning - no exclamation marks, all
devices working - so making USB2 work has its drawbacks.

If you have any idea where I can get a current XP driver for Logitech radio
receiver M/M C-BG17-DUAL it would be appreciated !!

Nevertheless, appreciate your help and support - Thanks, fellas!!

Sincerely, Len
