Well, that *is* the output from the exact same situation as before: I plugged in the USB stick and tried to copy a file to the hard disk with mcopy; the mcopy process eventually stalled. The output is the tail of /var/log/messages at that point of time, including all USB debug messages. When I pulled the stick out afterwards, the console only showed the same message again and again, seemingly in an endless loop: umass0: CAM poll I had to reset the machine. I didn't do anything different except setting hw.usb.umass.debug=3D-1. I'll retry the same thing once more later. If anything's different, then, I'll let you know.
