Hi Brian
Well I'm a bit confused.
dmesg report this:
..
uhci0 at pci0 dev 9 function 2: VIA Technologies VT83C572 USB Controller 
(rev. 0x02)
uhci0: can't map i/o space
uhci1 at pci0 dev 10 function 0: VIA Technologies VT83C572 USB 
Controller (rev. 0x61)
uhci1: interrupting at irq 9
usb0 at uhci1: USB revision 1.0
uhub0 at usb0
uhub0: VIA Technologies UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered
uhci2 at pci0 dev 10 function 1: VIA Technologies VT83C572 USB 
Controller (rev. 0x61)
uhci2: interrupting at irq 0
usb1 at uhci2: USB revision 1.0
uhub1 at usb1
uhub1: VIA Technologies UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub1: 2 ports with 2 removable, self powered
VIA Technologies VT8237 EHCI USB Controller (USB serial bus, interface 
0x20, revision 0x63) at pci0 dev 10 function 2 not configured
tlp1 at pci0 dev 12 function 0: DECchip 21143 Ethernet, pass 4.1
..
Especially the sentence: "uhci0: can't map i/o space" was worrying me.

If I pluck in a memory-stick dmesg reports this:
..
umass0 at uhub1 port 2 configuration 1 interface 0
umass0: USB Flash Disk, rev 2.00/2.00, addr 2
umass0: using SCSI over Bulk-Only
scsibus0 at umass0: 2 targets, 1 lun per target
sd0 at scsibus0 target 0 lun 0: <JetFlash, TS512MJF2B, 2.00> disk removable
sd0: fabricating a geometry
sd0: 500 MB, 500 cyl, 64 head, 32 sec, 512 bytes/sect x 1024000 sectors
sd0: fabricating a geometry
sd0: no disk label
..

But "mount_msdos /dev/sd0d /mnt" actually mount the bird. - And it's 
works ;-)
