CHIP.INI [USB]


[USB]
MAX_POWER_SUPPLY=Maximum power supplied via USB root port

Use this entry to tell the @CHIP-RTOS-PPC USB stack how much power can be supplied to a bus-powered device via each of the root hub's ports. The value is given in mA.
Default:
The default value is 500. This means that if you do not specify a value here, the USB stack assumes, that your hardware is able to supply up to 500 mA to USB devices per root port.
Example:
 [USB]
 MAX_POWER_SUPPLY=100
Since:
SC2x3 V1.00
Changes:
SC2x3 V1.02


[USB]
BULK_PER_FRAME=Maximum number of BULK transfers

Deprecated:
This setting has no effect on SC2x3, because the USB host controller of the SC2x3 determines the optimal value itself.
