Comment 7 for bug 156922

Problems with the Z22 were discussed at length on the gnome-pilot-list back in 2007.
It seemed at the time to be definitely a kernel/udev timing problem.

I do not have a Z22 to test with, but a couple of ideas, if you're up to it, include:
  o Try compiling the latest pilot-link and gnome-pilot source distributions.
      These are pilot-link 0.12.3 (A new release is imminent, so you could even
      check it out from source repository) and gnome-pilot 2.0.17.
  o If you have an infrared port, try getting that configured and use a 'serial'
      connection instead of 'usb' in gnome-pilot.
  o try using the 'visor' kernel module instead of the direct libusb mode.
      There are a couple of pages describing setting this up, such as:
