[sugar] Record-55 issue was B4 hardware failure (Was: Design Question)

[John Watlington]

Take a look at:
http://wiki.laptop.org/go/ 
XO_Troubleshooting_AV#Errors_communicating_with_the_camera

The majority of these problems are due to a latch on the flex cable  
connector coming loose.
If you disassemble the laptop, and find that it was due to another  
source, pleased either
add it to the guide or let me know.

Cheers,
wad
