A little background here. The only USB device I have is a Cpia Webcam.
It worked OK fine till I swapped MBs to an AK73 (ProA), and I got the same
symptoms you mention. Then no joy with with the camera. I had pretty much
given up hope until one day I was fooling around with an old scsi host
adapter, which I had plugged into PCI slot 5. LO and behold, on came the
camera's little green light and it worked fine. I found that plugging any PCI
card requiring an interrupt into slot 4 or slot 5 made the camera work OK.
[That could be a hint for you developers out there].
I subsequently found that renaming Snnhotplug in /etc/rc.d/rc3.d (so it
wasn't run at Bootup) and doing modprobe cpia made the camera work as well.
(with slot 4/5 empty)
Lastly, I found that adding 'Load "v4l" ' to /etc/X11/XF86Config made the
usb camera start up automatically when X windows loads.
I have video4linux build into the kernel.
All other usb stuff as modules (usbcore, usb-uhci, uhci, cpia-usb, cpia)
Here is my modules.conf:

Hope some of this is off help.
