Abstract: In a removable system formed from a host device and a slave device detachable from the host device, when the slave device sequentially detects a signal of a first voltage level and a signal of a second voltage level from the connected host device, the signal of the first voltage level is transmitted by a second signal line. Subsequently, when the host device detects that the second signal line is at the first voltage level, the host device interrupts drive of a first signal line, and executes initialization.
