 |
|
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.)

My best guess,
