If users move to using libusb directly, which will be available in the
next pilot-link release (0.12.0), there will be no TTY devices, and the
kernel visor module will be blacklisted.

For this reason, I've currently decided not to use HAL pda support in
gnome-pilot, and just to check the device/vendor IDs when I get a hal
callback.  It's working nicely and should support libusb mode too.  A
list of device/IDs may be ugly, but that's what you've got in effect by
using the visor module -- it's just that usbserial has the list, not
hal.

I am now watching this space...
