OTG transmission channel switching method and device and electronic equipment

The embodiment of the invention provides an OTG transmission channel switching method and device and electronic equipment, relates to the technical field of data exchange, is suitable for the electronic equipment with multiple OTG interfaces, and comprises the steps that when it is monitored that a first OTG interface of the electronic equipment is subjected to insertion operation, a first interrupt is triggered; the first OTG interface is any one of the plurality of OTG interfaces; determining whether a second OTG interface of the electronic equipment is in an OTG transmission state; the second OTG interface is any one OTG interface except the first OTG interface in the plurality of OTG interfaces; and when the second OTG interface is in the OTG transmission state, establishing a first OTG transmission channel through the first OTG interface, and disconnecting a second OTG transmission channel established through the second OTG interface. According to the mode, non-inductive switching of multi-channel OTG co
