USB controller for one or more USB connectors and method thereof. For example, a USB controller for one or more USB connectors includes: a detector configured to receive a first input signal from a first pin of a first USB connector and receive a second input signal from a second pin of the first USB connector and generate a detection signal based at least in part on the first input signal and the second input signal; a logic controller configured to receive the detection signal and generate a first control signal and a second control signal based at least in part on the detection signal; a driver configured to receive the first control signal, generate a drive signal based at least in part on the first control signal, and output the drive signal to a first transistor terminal of a transistor.

USB type-C connectors and related controllers with voltage control pertaining to disconnection detection

USB charging system and method. For example, a USB charging system includes: a first AC-to-DC conversion unit configured to generate a first voltage and a first current; a second AC-to-DC conversion unit configured to generate a second voltage and a second current; a first USB output port corresponding to the first AC-to-DC conversion unit; a second USB output port corresponding to the second AC-to-DC conversion unit; a switch connected to the first AC-to-DC conversion unit and the second AC-to-DC conversion unit; and a control chip connected to the first AC-to-DC conversion unit and the second AC-to-DC conversion unit and configured to open the switch and close the switch; wherein the control chip is further configured to: determine whether the first USB output port is connected to a load device and whether the second USB output port is connected to a load device.

Allocating a resource of a storage device to a storage optimization operation. An available resource of the storage device is monitored. Determining an allocation proportion of the resource allocated to the storage optimization operation, based on at least one of historical running information and a predicted value of a performance improvement caused by the storage optimization operation. Allocating the resource of the storage device to the storage optimization operation based on the available resource and the allocation proportion.
