Adding dynamic USB power support - Each scan module now has a current change callback which passes the available current as a parameter - No longer attempts to use the max 500 mA immediately, starts with 100 mA then goes to 500 mA after enumeration - If enumeration fails due to bMaxPower of 500 mA, then attempt again at 100 mA (might also be possible to go even lower to 20 mA in certain cases) - Now working with the Apple Ipad (no over-power messages) - Fixed Wake-up behaviour on Apple Ipad (and likely other iOS devices) - More effecient set_feature/clear_feature handling (device handler) - Initial power handling via Interconnect (still needs work to get it more dynamic)
