CONFIG_USB_GADGET_VBUS_DRAW: Maximum VBUS Power usage (2-500 mA)

General informations

The Linux kernel configuration item CONFIG_USB_GADGET_VBUS_DRAW:

Help text

Some devices need to draw power from USB when they are configured, perhaps to operate circuitry or to recharge batteries. This is in addition to any local power supply, such as an AC adapter or batteries.

Enter the maximum power your device draws through USB, in milliAmperes. The permitted range of values is 2 - 500 mA; 0 mA would be legal, but can make some hosts misbehave.

This value will be used except for system-specific gadget drivers that have more specific information.
