USB 2.0 and Windows XP Home with SP2

[Jim Cladingboel]

My Device Manager shows that I have two Standard Enhanced PCI to USB Host
Controllers, the drivers for which are USBEHCI.SYS, USBHUB.SYS and
USBPORT.SYS.
DevMan indicates these are all Version 5.1.2600.2180, dated 01/06/2002.
Am I correct in believing these are USB 2.0 drivers, capable of 480 Mbps
transfer speed ?
If not, then which drivers do I need to have installed?

Jim.

Jim, as I said to you before, my son's PC has drivers 5.1.2600.0 (date
unknown). You said that these were the USB 1 drivers, and I believe that
you are correct. I believe that the variant you mention above is
unlikely to be the USB 2 version. I believe, but can't confirm, since
I'm on a multi-boot, that the XP64 version uses version 5.2.3790.1830.
What I don't know, since I don't have the 32-bit XP here what version of
USB driver is used in that environment for USB 2.

Cheers,

Cliff

Jim.

This is what I have for USB 2.0 in Properties.
Under the driver tab:
Intel(R) ICH8 family USB2 enhanced USB host controller 2836.

Provider: Intel
Date: 4/10/2006
Version: 8.0.0.1008

In driver details:
c:\windows\system32\drivers\usbehci.sys
c:\windows\system32\drivers\usbhub.sys
c:\windows\system32\drivers\usbport.sys
c:\windows\system32\hccoin.dll
c:\windows\system32\usbui.dll

All are:
Provider: Microsoft
Version: 5.1.2600.2180 (xpsp_sp2_rtm040803-2158

As mentioned in another response, I don't believe the controller driver is
installed, USB is not enabled in the BIOS, PnP is disabled or you need to update the
BIOS.

If you don't have USB2 performance with SP2 installed, re-install the
chipset drivers for your system's motherboard.

Thank you, Brian,

Those MS Version details tally with mine, so I have all
the correct drivers installed.
I'm not sure what you mean by 'the controller driver'. Is there something
other than the drivers you have listed, if so please advise what I need to
do, or do you mean the ASUS mobo driver, which has always been ignored by
the O/S ?
Today I downloaded from ASUS and installed their P4VP1013.AMI update of
26/9/2005. I again checked that USB 2.0 was enabled, and that PnP was "on",
as it was in the previous BIOS.
This made no difference to transfer speed via mobo hub or PCI card.
I then downloaded from ASUS their latest chipset, VIA Hyperion 4 in 1
Version 4.51 of 16/3/2004. Unfortunately, this also made no difference.
I use a 744MB file to test transfer rates and while once getting a time of
85 seconds, it is more often between 95/105 seconds i.e. USB 1.0.
This problem is taking up 90% of my computer time, so if you have any other
thoughts I would be most grateful.
I had thought of buying another PCI to USB card, but if the same drivers
don't work on the mobo hub, that seems pointless.

Jim.

Thank Patrick, but if you see my reply to Brian, that hasn't worked for me
either.

Jim, are you sure that the external device is capable of the high speed
USB 2 speeds? The quote at the bootom of my post is from

http://pclt.cis.yale.edu/pclt/PCHW/usbfirewire.htm

Obviously being an Internet source, it is not definitive, but the last
bit is interesting : 'in practice a USB disk is unable to operate faster
than 10-16 megabytes per second.'. 744MB in 85 secs is nearly 9MB per
second or 72Mbits/second. This is considerably faster than USB 1.1 which
is either 1.5Mbps or 12Mbps. At the fastest (12Mbps) the transfer rate
in bytes for USB 1.1 would be 12 / 8 = 1.5MB/s. You appear to be getting
a lot more than that.

Of course it is possible that my math is bad, so please check it out.

Cheers,

Cliff

'The modern USB 2.0 port supports three specific transfer speeds:

* A "low speed" USB device transfers data at 1.5 megabits per second.
* A "full speed" USB device transfers data at 12 megabits per second.
* A "high speed" USB device transfers data at 480 megabits per second.

Unfortunately, a buyer has to be careful of the terminology.
Technically, USB 2.0 is a specification of the physical and electrical
interface specification. A few vendors claim to have USB 2.0 ports but
do not support high speed devices. So make sure that a device claims
"high speed" or 480 Mbs before buying it.

Converting to bytes, USB appears to be 60 megabytes per second, but in
practice it does not transfer data that fast. There is overhead, and in
practice a USB disk is unable to operate faster than 10-16 megabytes per
second.'

Nice catch Enkidu, your math is close enough, I totally missed the speed rate
mentioned.
744MB / 85 secs = 8.75 MB a sec. = 70Mbits a sec.

That means Jim is running at USB 2.0 speed.

Brian,

As I said to Cliff, his math is quite correct, but my PCI card specifically
claims to
"Support high speed (480 Mbps), full speed (12 Mbps) and low speed (1.5
Mbps).
Guess I'll just have to live with it... but I noticed in a post from Anna
(in November ?) she achieved around 20 MB/second (160 Mbps) using Acronis
True Image.

Thanks, Jim.

Jim, I suspect that the numbers mean *up to* those speeds! It reminds me
of the backup tapes that I buy that are rated at 800GB. That assumes 2:1
compression which is achievable only with special files. In most cases
you can only achieve 1.5 to 1.7.

Cliff
