Hi,
when i plug in my USB 2.0 device winxp gives a ballon at the right that says
This Device Perform Faster....
Controller is 2.0., device too, i get 1.0 speed less than 1MB/s.
Anyone can help ?
PCI card is DU-A2 Rev. D2
Thanks
I had that problem.
SC Tom is right. If your USB Properties do not say Enhanced (or you
don't see Enhanced in Device Manager), you need an updated driver. It
must say Enhanced.
I choose to update my driver and let Windows search for it. I don't
remember know where it found it exactly, but I did not go to any site
and download anything. My new driver is a Microsoft driver.
Here is some info I found from Microsoft when I was trying to figure
this out:
http://www.microsoft.com/whdc/connect/usb/usbfaq_intro.mspx.
I also made some notes about my situation as I went along:
Turning in a USB 2.0 device (like a printer) you might see a message
that says this device can perform faster if
it was connected to a high speed USB 2.0 device.
Maybe: The USB device can perform faster if you connect it to a High
Speed USB 2.0 port.
For a list of available ports, click here.
USB 1.X = 12.0 megabit per second (mbs) Full Speed
USB 2.X = 480 megabit per second, or 40 times faster than 1.1.
Right click My Computer, Properties, Hardware, Device Manager. Under
the USB Controller section
see if there is a red X.
Look in the Other device section (things with yellow question marks
and red X)
observe: Ethernet controller (with red X) who cares, I am wireless
PCI Modem (with red X) who cares, I don't use it
USB controller (with red X) here is the problem
Or maybe look here at this: Universal Serial Bus (USB)
Controller
This means the system has the ports, but the correct driver is not
installed. XP did not
come high speed drivers, but they do come in the service packs
(SP1), so it must now be
installed manually.
More information from Microsoft:
http://www.microsoft.com/whdc/connect/usb/usbfaq_intro.mspx
Right click the USB Controller in the Other devices section with the
red X in the question mark,
right click Properties and if it is disabled, click Driver and Update
driver, and let it search
for a new driver and hopefully find it and install it. Things will
refresh a few times.
The question marked red X on USB Controller will go away. You may be
able to just enable it,
but I did not try this.
Now look in the Universal Serial Bus Controller section for something
that says USB Enhanced Host
Controller - Enhanced is the key word which means high speed. If it
is not there, it is just a
USB 2.0, but not high speed.
After the update, there should now be at least one USB Enhanced Host
Controller. Does this mean that
now ALL the USB 2.0 connections are high speed? The driver version
for the USB device should now all
be 5.1.2600 or later. If not, upgrade them individually to the
current version.
You may (should) reboot after this to get your other USB device
working again. My wireless USB device connection didn't work after
the upgrade until I rebooted.
Under USB Printing Support it shows my correct printer which is the
thing that was complaining every
time I turned it on. No more complaints, always was 2.0 but now I am
now enhanced.
It is possible to configure a check box in the properties on the
device to never warn you about
errors. Probably not a good idea.
Some people hint that you need a BIOS update or change
something in your CMOS and some other
things. Could be, but not for me.
It all makes sense now.
