[help-mi]

Hello, Not included camera. the problem is that I connect over an ISP and all is well and sees the flash drive (using Medusa box)
Clicking the button generates all the signals as in the scheme (i.e. the phone is actually should already be included)
When connecting to LBP when you click on enable the current consumption 0 When the inserted battery is inserted and charging the current consumption increases to 0.42 amps but the image is not present in the phone, respectively, as the Bud turn on the phone in charging mode.

The phone when connected to the computer is defined as: sec s5pc210 Test B/D;
And cyclically connects and disconnects.

The buttons in the moves mode, respectively, is not working.
