Hi,

I have a motherboard , MACH Speed matrix P4M800 motherboard. Its states on the specs that it has USB 2.0.

I am running Fedora Core 4, kernel 2.6.15-1.1831.

When I do a lspci, it comes back as :

VT82xxxxx UHCI USB 1.1 Controller (rev 81)

Is there a configuration change or driver that will get it to USB 2.0 ? or is it just a misrepresenation on the board ?

Thx

The following URL has a little bit of information about USB versions.

http://www.gentoo.org/doc/en/usb-guide.xml#postkern

Look for the section named "A Technical Perspective". It's not much information but it does say what the names of the drivers are.

I tried looking at www.usb.org but all of their information is contained in PDFs. I don't know about you but I hate having to download PDFs just to get a little bit of information.

Anyway, as the gentoo site indicates, the EHCI is for version 2.0 while OHCI and UHCI are for version 1.1. You can look at dmesg to see what modules are being loaded at boot time. If your kernel ring buffer has lost its boot messages then you can look in /var/log to see if your system keeps a file of boot messages.

I don't understand what I have. All the specs on my board (P4M800) say its USB 2.0 . I have four USB ports on the back of the motherboard, and when I look in the boot log, I see 1 EHCI hub, and 3 UHCI hubs, which corresponds to the 4 USB ports.

Getting deeper into the owners manual, I see there is two, USB 2.0 headers on the motherboard that allows additional USB cables for the front panel or internal devices.

I still dont understand why the OS thinks the other USB ports are 2.0 though.

thx

ttt..

Anyone ?
