This does not work with 2.6.28-rc2 udev creates devices as usual, but /dev/ttyUSB0 fail. cat /dev/ttyUSB0 gives i/o errors, for example. gpsd try several times, and then fall back on opening in read-only mode. This works, but gpsd doesn't actually get any data at all from the unit. The pc is a core2duo laptop, using a 64-bit smp kernel. 2.6.27 is fine. I skipped 2.6.28-rc1 due to known breakage. I can test it if that might help.
