[Paparazzi-devel] Accessories on ardrone2 cause it to reboot after upload

[AndrewChambers]

I'm having problems with my ardrone2 reboot when certain GPS units and
USB-UART bridges are attached to its USB port. 

In Paparazzi Center after hitting the "Upload" button, the vehicle will
reboot. The LEDs turn off and then each of the four propellers will slightly
spin in sequence. (Typically start-up sequence)

I can also cause the ardrone2 to reboot if I telnet in and try to read the
USB port. For example: cat /dev/ttyUSB0

Has anyone seen similar behaviour and is there any way to fix this?

Details:
Software: HEAD of master branch on git
NON working hardware:
BU-353S4 or a USB-UART bridge (http://www.adafruit.com/products/954)
connected to SPK GS406

Working hardware:
If I use a different USB-UART bridge
(http://www.hardkernel.com/main/products/prdt_info.php?g_code=G134111883934)
connected to the SPK GS406, it works fine.
