USB 2.0 drive runs at USB 1.0 speed on XP Professional SP2

[Guest]

When plugging in a new USB 2.0 hard drive, I get this message. "
The Generic USB Hub is a HI-SPEED USB device and will function at reduced
speed when plugged into a non-HI-SPEED port."

I have installed SP2

You can have all the best software, latest patches, newest drivers... but if
you do not have the hardware, it all does you no good.

Your drive is not the only component that has to be USB 2.0 - so do your USB
ports themselves.

Tom, does your Motherboard have built in USB 2.0 ports or are you using a
PCI Card with USB 2.0 ports or none of the
above?

My PC has USB 2.0

I should have said this. I have IBM Thinkpad T40 with USB 2.0. When the
message shows up, it asks you to click on available 2.0 ports and it shows
them.

THis is an IBM T40 Thinkpad with USB2.0. When the message appears, it gives
you the option to view available 2.0 ports and they are shown as available.
It says plug into a 2.0 port, but I don't see how to control that. I have two
physical ports and the same symptom occurs on both.

Have the latest chipset drivers installed from IBM?

Check BIOS USB controller settings, some default to "Full Speed" (12Mbps)
instead of "High Speed" (480Mbps) or whatever IBM call this option if they
provide it.

There is no setting in BIOS to control this.

I verified with IBM that I have the latest chip set drivers. And the
motherboard was recently replaced.

So what's the problem? It's telling you that your hub is indeed hi-speed USB; that's good. How do you know it's running at 1.0
speed? Because of the message or because the transfers are slow?

 

[Guest]

Both. Copying a test file runas at just under 1MByte/sec and backups of my HD
run 16-24 hrs or more.

The message does not say that it is running at USB 1.0 speeds, it doesn't sound like an error at all. Honestly, something doesn't
add up. If you plug a hi-speed device into a low-speed port, you get that message. Yours should be "The DISK DRIVE is a HI-SPEED
USB device and will function at reduced speed when plugged into a non-HI-SPEED port." Either that, or you should get the message
you wrote only when you unplug, then plug in the hub. You shouldn't get the message about the hub when you plug in the _drive_.
That doesn't make sense. Does this happen every time you plug in the drive? Try plugging in the drive directly to a port instead
of the hub. Does the drive support USB 2.0? What make/model is it?

I am using two different Western Digital USB 2.0 drives (120G and a 250G new
book style drive). I plug them directly into one of the two USB ports on the
laptop. There are no extra hubs etc. Just the drive and the laptop. Yes it
happens every time.

If both drives give you the message and you have the latest chipset drivers
downloaded/installed from IBM - AND your mottherboard was just replaced on
this system - then perhaps something is wrong with the motherboard that you
got replaced. Perhaps it only has 1.1 USB. Perhaps you should go purchase
an external (PCMCIA/PCCARD) USB 2.0 card and try that. If that works - then
perhaps you should complain to those who did the hardware replacement for
you.

 

[Guest]

That is what I have decided to do. I just ordered an Adaptec two port PCMCIA
card from Dell. I lean to a problem in XP, but I can't take the time to
reinbstall and bring up all the apps. If the card works as a workaround, I
will just call it good.

 

[Guest]

BTW, XP says I have USB 2.0 and shows the available ports, so I feel like the
motherboard is OK. I think it is an XP bug.

I couldn't disagree more.

It is not an XP bug because I know too many people - some with identical
hardware to yours - that do not have the issue you are having. It may be a
problem caused by mixed software on your system or some corruption in a DLL
or registry or driver that is keeping your internal USB 2.0 (motherboard)
from working. But it is particular to your system and not a Windows XP
bug... It's a Tom's IBM with Windows XP SP2 installed bug... *grin*

Heck - it could be corruption, and if so a repair install might fix it.

If that failed - given the time already put into this - an image of the
system with cloning software to external hardware followed by a fresh
install (Windows XP SP2 and all updates) alone to see if it works properly
like that might give a better idea of the problem. After all - if it works
with a clean install, you know it is not a Windows XP Bug - but a problem in
your particular install *and* that your hardware is fine. And - since you
cloned it - restoring it back to the way it was should be a few more minutes
of your time.

Let me elaborate. When I say it is an XP bug, of course I mean that it is
somewhere in the operating system which of course is XP. But I fully
understand that it could be as you say a faulty install, corruption etc. As
such, I understand a new install is a valid option to troubleshoot this. I am
just rather frustrated by the way XP presents the issue. But oh well.

I have a thinkpad T40p and win XP fully updated, and I've added the nost recent device drivers from Lenovo, and have _exactly_ the same problem as described in this thread. USB 2.0 devices are recognized as such, but all operate at USB 1.0 speeds, and I get the warning mentioned as well. Oddly, I was able to make my USB ports work in 2.0 mode by disabling BIOS USB support, however, now several weeks later, my USB is workign only in 1.0 mode agian, and I'm not aware of having made any software or hardware changes. I've also tried every immaginable combination of devices, restarts, bios settings, etc, to no further avail.
