Bug Description
The GPS LT-20 (USB-id 1163:0200 DeLorme Publishing, Inc.) sends standard NMEA commands over the USB. After connecting the device, a node is created as expected:
dmesg:
[34527.963000] usb 1-1: new full speed USB device using uhci_hcd and address 6
[34528.124000] usb 1-1: configuration #1 chosen from 1 choice
[34528.130000] cypress 1-1:1.0: DeLorme Earthmate USB converter detected
[34528.131000] usb 1-1: DeLorme Earthmate USB converter now attached to ttyUSB0
Output from: cat /proc/bus/

E: Ad=81(I) Atr=03(Int.) MxPS= 32 Ivl=6ms
E: Ad=02(O) Atr=03(Int.) MxPS= 32 Ivl=6ms
but then
cat /dev/ttyUSB0
just moves the cursor to the next line and waits until I press Ctrl-C without producing any output.
In Edgy Eft, the same command produces output similar to:
$GPRMC,
$GPGGA,
$GPVTG,
etc...
Because of this communication bug, neither gpsd nor gpsdrive can communicate with the Earthmate.
