Broken USB-Connection

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use the LRTimeLapse-Function with an external timer and connect the camera 
with USB to a tablet.
2. After one hour the connection seems to broke and i try to reconnect (Nothing 
changed, Display was always on, cable was plugged in always)
3. Camera stops taking pictures with the message: SD-Card is defect. If i 
restart Camera and App, everything is OK.

What is the expected output? What do you see instead?
I don't want to see this error ;-)

What version of the product are you using? On what operating system?
0.30.27_2 on Asus Transformer TF101 with Android ICS (Original FW). Camera: 
D5100

Please provide any additional information below.

What interval did you use?
Did you frequently checked the image?
Had the application enough time between captures to download the JPG from 
camera?

Intervall: 5 seconds
I checked the picture in 3 to 10 minutes periods. Maybe i clicked two times on 
the button to get the image, because i thought i missed it?!?
What capture time is good? Is it a problem, if i make every second a picture, 
but i download only every 2 minutes a picture?

The camera needs time to write the image to sdcard and it depends on camera 
model and the sdcard used and also on shutter speed. With D7100 I can use 
around 3-4sec interval but with D5000 it is more like 6-10sec.
The camera first writes the image to sdcard and then notifies the application 
about it. Then if you checked the image review in LRTimelapse help screen the 
application downloads the jpg image and deletes it. If your intervalometer 
makes a capture while the application tries to execute the command for 
downloading or deleting the image, the command will be probably not executed in 
full.
In the upcoming test version I changed the way the image is downloaded and 
deleted (also added 2 options regarding this while in LRTimelapse help screen), 
will see if this helps.
To get some approximation how much time the camera needs, try to measure the 
time between the intervalometer capture start and the popup message with the 
file name you get on LRTimelapse help screen.
