* The motherboard is a MSI K7T266 Pro2: up to 6 USB 1.1 ports.

>Description:
As a side note, i previously posted about this problem on current@ during
the release cycle of 5.3-RELEASE, but focusing on using a USB thumbdrive
at this time. I realize later that it seems to be a general USB support
problem, not just a relative one to the pendrive i use at this time.

After trying the BETAs ans RCs just before the release of FreeBSD 5.3-RELEASE,
i discovered that i can't use any USB ports on one of my systems (i did not
encountered this problem on my notebook for example).

Before that, i had use USB on this machine without problem running RELENG_5_2
(5.2.1-RELEASE-p11 at this time): i can use, without any problem, a 64MB USB
thumbdrive, a USB mini notebook mouse and my Palm m500.

But since this host follow the RELENG_5 branch for now, it seems impossible to
have the USB subsystem working properly.

So this *new* problem appears only on one of my machine and seems to be related
to the motherboard i use: the K7T266 Pro2.

As a side note, i previously posted about this problem on current@ during
the release cycle of 5.3-RELEASE, but focusing on using a USB thumbdrive
at this time. I realize later that it seems to be a general USB support
problem, not just a relative one to the pendrive i use at this time.
