Abstract:
1. A data card updating method, comprising: connecting, by a personal computer, with the data card through a universal serial bus (USB) interface, wherein the USB interface is mapped to a remote network driver interface specification (RNDIS) interface on a device manager of the personal computer; sending, by the personal computer, an interface switching request to the data card through the RNDIS interface when internal software of the data card needs updating, wherein the interface switching request is configured to instruct the data card to switch the RNDIS interface into a personal computer user interface (PCUI); determining, by the personal computer, whether the RNDIS interface is switched to the PCUI successfully; and transmitting, by the personal computer, a software update package to the data card through the PCUI to perform installation when the RNDIS interface is switched to the PCUI successfully.
