Hello, I have a FreeBSD soekris box and I had a USB hub with 3 usb serial devices attached. It was working fine for about a year or so, but then it started getting flakey. I lose the com ports. I'm wondering, maybe it's time to get a new powered hub? I've attached what I see in dmesg now: ucom: Waiting for a TTY device to close. ucom: Waiting for a TTY device to close. ucom: Waiting for a TTY device to close. ucom: Waiting for a TTY device to close. ucom: Waiting for a TTY device to close. ucom: Waiting for a TTY device to close. ucom: Waiting for a TTY device to close. ums0: at uhub2, port 2, addr 4 (disconnected) ugen1.5: <Prolific Technology Inc.> at usbus1 (disconnected) uplcom1: at uhub2, port 3, addr 5 (disconnected) ugen1.2: <NEC Corporation> at usbus1 uhub2: <NEC Corporation USB2.0 Hub Controller, class 9/0, rev 2.00/1.00, addr 2> on usbus1 ... ugen1.5: <Prolific Technology Inc.> at usbus1 (disconnected) uplcom1: at uhub2, port 3, addr 5 (disconnected) uhub_reattach_port: giving up port reset - device vanished uhub_reattach_port: giving up port reset - device vanished ugen1.2: <NEC Corporation> at usbus1 uhub2: <NEC Corporation USB2.0 Hub Controller, class 9/0, rev 2.00/1.00, addr 2> on usbus1 uhub2: 3 ports with 3 removable, self powered ugen1.3: <Prolific Technology Inc.> at usbus1 uplcom0: <Prolific Technology Inc.
