If communication with programmers is lost randomly during device operation (for example
device programming), please close other programs, especially programs which consumes
large amount of system resources (multimedia, CAD, graphic applications and so on).
Note: We also recommend to use computer USB ports placed on back side of computer and
directly connected to motherboard, because computer USB ports connected to computer
motherboard indirectly - via cable, may be unreliable when using high speed USB 2.0 transfer
modes. This recommendation is valid not only for programmers, but also for other devices.
