A few minutes ago I unplugged and replugged a PL2303 serial adapter in an RPi3 running r329495. The serial console announced the disconnection with ugen0.4: <vendor 0x067b product 0x2303> at usbus0 (disconnected) uplcom0: at uhub1, port 2, addr 4 (disconnected) uplcom0: detached followed by a torrent of unprintable garbage. Then it calmly announced <vendor 0x067b product 0x2303> at usbus0 uplcom0 on uhub1 uplcom0: <vendor 0x067b product 0x2303, class 0/0, rev 1.10/4.00, addr 4> on usbus0 The displaying host is a Pi3 running the latest Raspbian. It's not clear how much, if any, of the oddity is an artifact of the display. Experience to date suggests none. Far as I can tell the pl2303 and the host RPi3 are working normally. I've never done this experiment before on a Pi3, but have done it many times on a Pi2 and nothing of the sort has happened. Hope this is of interest to someone... bob prohaska
