mount_msdos /dev/da0s1 /mnt/usb ->dev not configured

[Lars]

Hi all,

Hardware:
IBM TP R40;
SONY 256 MB USB2 "Microvault"
(works flawlessly on other sytems and on same system under WinXP);

OS is FBSD 4.8;

Kernel:
device	scbus
device	da
device	uhci
device  ohci
device	usb
device	ugen
device	uhid
device	umass
are enabled;

/var/run/dmesg.boot:
uhci0: <Intel 82801DB (ICH4) USB Controller USB-A> port ...
well, it get's recognised;

I noticed that all PCI and USB hardware is on IRQ 11, 
may that be the cause?

So, dear list, what am I doing wrong?

Kind regards & TIA,
Lars.
