I have Windows 7 home prem.
I have GPSinfo.
I have a BU-353
I use it on Opncpn.
This was working fine on my windows 7 machine.
I installed it on my Ubuntu 14.04 mach using GPSD and GPSD-clients.
It worked fine.
I came back to my windows 7 machine and it does not work.
When I start GPSinfo and start the GPS the courser moves down the screen one line at a time like it
is trying to work but no data.  Just blank.
I installed the driver recommended to OmarKN (
My BU-353 still does not work.  When I plug it in sometimes (diff usb ports) the message says
"installing driver" I get a blue screen something about a zero.  It goes by very fast. 
The computer restarts and if I remove the BU-353 everything is fine except no GPS.
Sometimes I plug in the BU-353 (diff port) and it tries to work.  No blue screen. 
Then I start GPSinfo and start the GPS.  The courser drops down the screen one line
at a time like the GPS is trying to work but the lines are blank.  No info. 
The red led is blinking.
The BU-353 worked ok before but started to not work before I changed the driver.
I changed the driver in control panel manually.
It still works on the Ubuntu machine. 
I tried all three USB inputs on the windows machine and it does not work.
It seems like there is something keeping the info from being read by the computer.

I have a GlobalSat ND-105C Micro USB GPS that I have tried to run on both my HP laptops which have Windows 8.1 running. The software seems to function for about 30 seconds reading GPS data, and then stopped with a message that says GPSinfo.exe has stopped working. The Windows compatibility software detection says that the GPSInfo is NOT compatible with windows 8.1.

I have done everything I know how to do to get this issue resolved short of through the system overboard.

Please help>..

I wonder where I can buy a new battery to replace the old. The reference sample inside the battery is EXA AL553436B.
Thank you.

I ve been reading all the posts interested on fixing and getting to know the equipment as I just ordered one via Ebay here in Panama.  Once I receive it, my question would be, is it neccesary I immediately look for a way of opening it and solder this antenna to avoid rattle?  I want to have everything running perfectly and I am in love with this device as per what I have read!  thanks!

USB GPS on Android is only for Android 3.1 and above.

Android 2.3.7 does not support "USB Host Mode", which is required for using a USB GPS on your Android device.

Know compatible USB devices for Window 10 are

For serial devices if you have the cable set BR305-USB8 it will work.

Also the DG-200 is compatible

For the BU-353 please read this work around

For the DG-100 please read this work around

The protocol is proprietary, ask GlobalSat for the protocol. I have them but cannot send them.
I have done an open source implementation here:
