If more than 300 mA current is needed by the board, the PC may be damaged or the
current supply can be limited by the PC. As a consequence the board is not powered
correctly.
current supply can be limited by the PC. As a consequence the board is not powered
correctly.
2. 300 mA is requested at enumeration (since JP1 must be OFF) so there is risk that the
request is rejected and the enumeration does not succeed if the PC cannot provide
such current. Consequently the board is not power supplied (LED LD3 remains OFF).
