USB: pl2303: use interface device for debug (7b5789a8) · Commits · 戴 / test

Use interface rather than usb-serial device for debugging interface related operations. This gives more descriptive messages, such as [ 905.669436] pl2303 1-4.1:1.0: 0x40:0x1:0x8:0x0 0 rather than [ 341.943535] usb 1-4.1: 0x40:0x1:0x8:0x0 0 Signed-off-by:
