Be sure you have fixed a satellite position and unplug the wifi dongle or others device to avoid powering issues. Be sure gpsd or another process is not fighting for the same serial connection.
Inspector is very CPU demanding and is normal 100% in Raspberry 2, we will optimize this in v0.9.0. GP is the right source (talker), not GPS.

Hi!
Thanks for a fast respons, WAY better than price brands like Garmin!!

Replaying in  order of appearance above:

1. GPS info / Inspector window:
Well, I get 1 value before it freeze, as example [Longitude,age: 0.2] or  [Time, source: GP] , and so on, but must restart Inspector between each reading. I get only 1 value before it freeze.  No matter how long I wait. Reset button doesn't respond/give a new value. When closing window, raspberry says "Inspector does not seem to be responding"

2: GPS fix
I can see NMEA output by using cat /dev/ttyUSB0.
Can confirm FIX  by running GPSMON from a standard Jessie distro (not openplotter)

3. Power: 
I have tested with two different power adapters of known brands, rated 5.1V/2.1A and 5.25V/2.5A.
I use a short (40 cm)  cable. I've also tried with a another USB-cable.
And tried without WiFi (but with keyboard, mouse and HDMI instead of WiFi).

4. External Hardware: 
Nothing else is connected than above.

4: Fighting for serial/GPSD:
I'm a newbe. How to check processes fighting for serial connection?
SUDO PS AUX | GREP GPSD doesn't show anything using GPSD, besides grep it self. 
(No other software has been installed. I downloaded latest img to a  SD card and pluged it in, connected to WiFi, apt-get update and upgrade. Thats all. What other process could it be fighting?)

Also checked baud rate with STTY -F /dev/... , it is 9600, which also is what Adafruit says is default. Set up a serial input in openplotter, at 9600.

With the MiniGPS tool you can set the update frequency to 1 Hz and try again.
Lowering the speed to 4800 or 9600 is also worth a try

Default is 9600 Baud and 1 Hz. I've checked baud rate ant it is 9600, but not update rate.
MiniGPS tool could be worth a try anyway, just to check.
