I get something similar too. The Device Node is created all right.

Yes, I also get something similar to this.

I do not only see da0 above and this command results in: "mount_msdosfs:
/dev/da0: Invalid argument"

You told me how to mount my flash disk in case the command "ls -l /dev/da0"
results incomplete or I have the disk raw formatted. But what should I do if
I get all similar to what you get? In other words, how do you mount your
flash disk?

Thanks for your feedback.
