Hello, On an NetBSD 6.1.5/amd64, when I connect a second USB connected disk to the machine, NetBSD freezes. Unable to connect remotely; hard reboot required.
Questions: 1) The machine has two usb ports, with uhub0 and uhub1 first attached resp. to these ones; the uhub2 cascading from uhub0 and uhub3 from uhub1. uhub2 has 6 ports removable; uhub3 has 8 ports removable; Since in /dev/ there are only 8 devices (from usb0 to usb7) could this be the problem? (6 + 8 = 14, even if I have only one USB device---first disk---and the second disk is only the second device; but how are the device nodes assigned to one USB port?) 2) The two USB disks are from the same vendor (Western Digital) but not exactly the same model (not the same capacity). Could the USB driver be confused by two similar devices connected to the same(?) USB tree? 3) Physically, on the machine, there are USB ports on the rear, and USB ports on the front. Does somebody know if front ports could be "duplicating" rear ports, that is slots on the front be in fact connected to the same ports as the rear ones causing conflict? I'm trying to find what is causing this misbehavior. And a freeze is rather annoying for a node that is mainly supposed to be administrated from remote...
