I created some new logs when pointing towards a lamp here.

Initialization (160Kb) of the camara under windows, and then record.
Frame data extracted from packet "80 01" to "80 02" winframe2.txt (147Kb) (Reorganized: winframe2b.txt) (147Kb)

STV-registers

• The text-files could be currupted! I just made some debug messages to syslog, and the text are sometimes clipped. I'll do some better logs soon.
  
• frame_add() is called when USB-packet looks like "02??XXYY", where data[0]==2, data[3-4] XXYY is rawdata-length and data[1] is unknown.
• Note that data[1] seem to have something to do with the framelength. Short frames have always low value on data[1].
  
• All frame-data starts with "F9 97" (resolution perhaps?)
  
• The sensor has built-in usb-support since there are only one IC in the camera. (Seems to be related to STV0680)
