 That's interesting.

 I have an Option Globetrotter GTMAX 7.2 3G card that also includes a
 so-called "Zero Configuration" feature that identifies as:

 Mar 27 14:33:12 radziecki kernel: cd0: Attempt to query device size

 but for me this is just a CD-ROM device, and it works. It is also
 read-only.

 1) This will not fix your issue but can you try umass.c and usbdevs (no
 need to install ubsa.c) patches from:

 http://akson.sgh.waw.pl/~saper/FreeBSD/gt/zeroconf/

 I wonder what happens to your system after this :)

 2) Can you compile your umass module with -DUSB_DEBUG and set

 sysctl hw.usb.umass.debug=3342336

 To set -DUSB_DEBUG the easiest way is to apply

 and then

 cd /sys/modules/umass

 make obj all

 And "make load" as root

 Provided you don't have umass in your kernel already.
