Thanks for responding.
I have been left looking a bit of a fool here. The first few times I
attached the card, the messages popped up in dmesg alright. But there
was no /dev/da0* device, and I was utterly confused. The confusion
became confounding when I just attached the card this last time, and
whoa ... the file manager pops up a prompt to open up the microSD disk
drive, and the /dev/da0[s1] devices are there, of course.
I have no idea whether this is a problem with my FreeBSD system or a
problem with the mobile/card or no problem at all. I have no idea too
what will be the results when I attach the card the next time. But I do
remember something which might be relevant. A couple of months back, I
attached the mobile+card to Windows XP a few times. 5-6 times the device
manager showed an unknown device, and the final time I attached it, the
drive in the card magically popped up. This gets besides the FreeBSD
issue but makes a nice story. I took the mobile to the authorized Nokia
dealer, and he said the microSD card is not supposed to show up at all
with the handset model I have. I even verified this in front of me with
a brand new handset (same model) and brand new microSD card. As per him,
the error was not the 5-6 times device manager showed unknown device,
but the final time when the disk showed up. He further stated that the
mass storage device is supposed to work only when the Nokia connectivity
driver is installed.
I returned home, installed the driver and - yes - the card attaches
consistently and smoothly.
Now the wheel starts spinning all over again in FreeBSD : - )
Any clues / tips ?
