Same result as if I start coldsync before hotsync.

I set that debug option as well as a few others and copied the output at
the end of this message. I noticed a couple odd things. First, I don't have
a configuration file: ~/.coldsyncrc

Second, /dev/ttyUSB1 doesn't seem to be readable. However, these are the
ownerships and permissions:

  # ls -l /dev/ttyUSB1
  crw-rw----  1 root dialout 188, 1 2006-02-11 00:22 /dev/ttyUSB1
  # groups
  marc disk dialout cdrom floppy audio src video plugdev staff dev

Finally, here is the output from coldsync with debug options:

  # coldsync -p /dev/ttyUSB1 -t libusb -d IO:5 -d sync:5 -d misc:5 -d net:5 -v -v -v -mI
