Abstract:
A method of an embodiment enables locking of downstream ports of a USB hub controller in an electronic apparatus. The method includes the determination step, the assertion step and the lock step. The determination step determines, with a BIOS, whether a lock setting has been made on each of the downstream ports. The assertion step performs, with the BIOS, assertion control for resetting the USB hub controller. The lock step performs, with the BIOS, lock control during the assertion control based on whether the lock setting has been made.
