I have gps unit connected via USB-serial (pl2303).
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.
