Hello Michal,

Here is my output of usbdevs -v.

Controller /dev/usb0:
addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), 
Intel(0x0000), rev 1.00
  port 1 powered

Controller /dev/usb1:

Controller /dev/usb3:

For what its worth, earlier this week I found a work around.  By doing a 
'cat /dev/null > /dev/da0'  the /dev/da0s1 appears and is 
mountable/readable/writable.

Thanks much
