On my Lenny system, USB devices (mouse, external drive, etc.) are only

How are you checking if they are detected (typically one would watch
syslog or dmesg)? If the kernel doesn't recognize them udev can't do
anything about it.

Syslog. Note that they are all detected fine if they are plugged in before
the boot process, so clearly the kernel can recognize them.

But it's also the kernel who should recognize them later. Udev runs in
user space (AFAIK). Do you have a standard kernel or self-compiled. Do
you get *any* response in syslog? I'm not sure I can help you, but these
are things I would look at first.

Standard 2.6.24-1-amd64 from the Debian package.

Could it be some kernel module that isn't being loaded? Anyone have an
insight? I'm using the same Debian release on my tower with the same USB
devices flawlessly, but there I'm using the K7 kernel (older CPU).

could it be an ordering thing, I have a logitech 9000 webcam, if it is
plugged in at boot up my usb sounds doesn't work and my multicard reader
doesn't work. I have to unload a few modules and load them in the right
order.

what does lsusb show you
