Abstract
An electronic device includes a communication control unit configured to perform an enumeration process, and a charging unit configured to charge a battery unit with power supplied from an external device. If a voltage of the battery unit is higher than a predetermined voltage, the communication control unit allows to perform the enumeration process with power supplied from the battery unit.
Claims20
An electronic device comprising:
- a communication control unit configured to perform an enumeration process;
- and
- a charging unit configured to charge a battery unit with power supplied from an external device,
- wherein the communication control unit performs the enumeration process with power supplied from the battery unit when a voltage of the battery unit is higher than a predetermined voltage, and
- wherein the communication control unit disables the enumeration process when a voltage of the battery unit is not higher than the predetermined voltage.
A method comprising:
- charging a battery unit with power supplied from an external device;
- causing a communication control unit of an electronic device to perform an enumeration process with power supplied from the battery unit when a voltage of the battery unit is higher than a predetermined voltage;
- and
- disabling the enumeration process when a voltage of the battery unit is not higher than the predetermined voltage.
A non-transitory storage medium that stores a program causing a computer to perform a method, the method comprising:
- charging a battery unit with power supplied from an external device;
- causing a communication control unit of an electronic device to perform an enumeration process with power supplied from the battery unit when a voltage of the battery unit is higher than a predetermined voltage;
- and
- disabling the enumeration process when a voltage of the battery unit is not higher than the predetermined voltage.
An electronic device comprising:
- a communication control unit configured to perform an enumeration process;
- and
- a charging unit configured to charge a battery unit with power supplied from an external device,
- wherein the communication control unit performs the enumeration process with power supplied from the battery unit when a remaining amount of the battery unit is higher than a predetermined amount, and
- wherein the communication control unit disables the enumeration process when a remaining amount of the battery unit is not higher than the predetermined amount.
A method comprising:
- charging a battery unit with power supplied from an external device;
- causing a communication control unit of an electronic device to perform an enumeration process with power supplied from the battery unit when a remaining amount of the battery unit is higher than a predetermined amount;
- and
- disabling the enumeration process when a remaining amount of the battery unit is not higher than the predetermined amount.
A non-transitory storage medium that stores a program causing a computer to perform a method, the method comprising:
- charging a battery unit with power supplied from an external device;
- causing a communication control unit of an electronic device to perform an enumeration process with power supplied from the battery unit when a remaining amount of the battery unit is higher than a predetermined amount;
- and
- disabling the enumeration process when a remaining amount of the battery unit is not higher than the predetermined amount.
