Fixing USB Keyboard & Mouse Boot Problems in Ubuntu

Sometimes on startup, Ubuntu does not recognize my USB Keyboard & Mouse. This problem is frustrating as Windows seems to recognize them.

It took me a while to recognize the root of the problem was with the USB 3.0 ports on the Motherboard. By moving the usb connections to the USB 2.0 ports on the motherboard this problem was solved.

Problem: USB Keyboard and Mouse dont work on boot up.
Solution: Move the connectors to the devices from a standard USB 3.0 port to standard USB 2.0 port(check with your motherboard manual for specifics)

Downloading Garmin GPS Data in Ubuntu

One of the simplest ways to download Track, Waypoint and Route information from your Garmin GPS in Ubuntu is using gpsbabel.

{adinserter 3}

Install gpsbabel via apt-get

sudo apt-get install gpsbabel

Connect the gps via the cable provided to the serial port of the computer or via a serial to USB converter to the USB port on your desktop/notebook.  To extract the infrormation all you need to do is, execute the following command:

gpsbabel -r -t -w -i garmin -f /dev/ttyUSB0 -o gpx -F data.gpx

The above command copies Routes(-r), Tracks(-t) and Waypoints(-w) from a garmin device (-i garmin) located at Serial-USB interface (-f /dev/ttyUSB0) and saves the info (-o) in the standard gps format (gpx) in the file data.gpx. You can omit the information you dont require and even choose other fromats like kml for google earth:

gpsbabel -r -t -w -i garmin -f /dev/ttyUSB0 -o kml -F data.kml

You should now have a file “data.gpx” which can be used to retrive or map your gps data.
