convert USB2.0 to USB1.1

[Tutu]

I have a USB analyzer which can only capture Data for upto 12Mbit/
s. When I connect a device which has a USB2.0 protocol on it, the USB
Analyzer is not able to catch this information. How can I force one of
my computer ports to work as USB 1.1? Is there a way? Thanks in
advance.

You could try the following.

Go to Device Manager. Find the USB section. One of the USB entries
has the word "Enhanced" in it. Select that entry. Do "properties"
on it. At the bottom of the Properties for the Enhanced entry,
there is a "Device Usage" box. It has values like

Use this device (enable)
Do not use this device (disable)

Change the setting to "disable".

Then try your analyzer. That is what I'd try.

It is also possible, that USB2 could be disabled in the
BIOS, but not all BIOS have the same control features
listed on the screen.

You should notice a visible different in UVCView after you do
that also. A bunch of entries should disappear near the bottom.
I would close UVCView, before you start the process of changing
the Device Manager. Once the change is made in Device Manager,
run UVCView again, and the USB2 section should be gone. (On my
ICH5 Southbridge, the USB2 entries are near the bottom of the
UVCView window.)

You could try connecting it through an external USB 1.1 hub to the PC.

It is posible to change usb protocole from BIOS
For this porpse firt Make backup of your bios
then extract bios.bin file in your working folder
identify the usb bus file that contan usb codes just like Processor codes( When u update Processor Code it run fast & smoth) change the usb protocole/Code file
with high speed USB 2.0 Codes file ( extractin from other pc that contan high speed usb )
repack bios.bin file then flash into the pc
restart pc you are notes ur usb bus detet as high speed
b/c all type of bus rate depend on BIOS that contain first startup drivers/codes.
You also develp our own code for USB or other Hardware.


I test on many typeof motherboard
my first exparement on (intel 810 lmrt)
2nd (810 DST) then (810 Mini), (815) , etc

Replying to a post from 2007? What an idiot.

Why? It's a valid query that was not answered and now is. When you look at
Google ALL of the posts, including the belated correct response, will be
there for those doing the research. Nearly every e-mail in the free world is
stored at Google and other such repositories for perpetuity.

HTH,
