A method for dynamically managing a removable device includes the following steps: generating a device insertion interrupt to indicate that the removable device has been coupled to a connection interface when detecting an insert event corresponding to the removable device; clearing the device insertion interrupt before a processing mechanism corresponding to the connection interface handles the device insertion interrupt; and identifying a specification of the removable device to dynamically manage the removable device according to the specification; wherein when the specification corresponds to a first specification, a first management scheme is activated to manage the removable device, when the specification corresponds to a second specification, a second management scheme is activated to manage the removable device, and the first specification is different from the second specification.
