I wondered whether they might have been due to running with a KTR-enabled kernel but in just the last 7 hours I've been running on stock GENERIC and they're still happening. I get this set of messages for each disconnect: Jan 24 15:40:13 predator-ii kernel: ums0: at uhub0 port 2 (addr 2) disconnected Jan 24 15:40:13 predator-ii kernel: ums0: detached Jan 24 15:40:14 predator-ii root: Unknown USB device: vendor 0x046d product 0xc025 bus uhub0 Jan 24 15:40:14 predator-ii kernel: ums0: on uhub0 Jan 24 15:40:14 predator-ii kernel: ums0: 8 buttons and Z dir. Rarely, twice that I can recall over the course of a couple of weeks, the mouse fails to reconnect but comes good with a physical disconnect/reconnect. Here's a recent (condensed) history running with stock GENERIC: Jan 24 15:47:04 predator-ii kernel: ums0: at uhub0 port 2 (addr 2) disconnected Jan 24 16:15:53 predator-ii kernel: ums0: at uhub0 port 2 (addr 2) disconnected Jan 24 16:21:46 predator-ii kernel: ums0: at uhub0 port 2 (addr 2) disconnected Jan 24 16:25:42 predator-ii kernel: ums0: at uhub0 port 2 (addr 2) disconnected Jan 24 16:26:17 predator-ii kernel: ums0: at uhub0 port 2 (addr 2) disconnected Jan 24 16:37:01 predator-ii kernel: ums0: at uhub0 port 2 (addr 2) disconnected Jan 24 16:39:22 predator-ii kernel: ums0: at uhub0 port 2 (addr 2) disconnected Jan 24 16:56:28 predator-ii kernel: ums0: at uhub0 port 2 (addr 2) disconnected Jan 24 17:06:36 predator-ii kernel: ums0: at uhub0 port 2 (addr 2) disconnected Jan 24 19:20:58 predator-ii kernel: ums0: at uhub0 port 2 (addr 2) disconnected Jan 24 21:17:30 predator-ii kernel: ums0: at uhub0 port 2 (addr 2) disconnected Sometime during 16:00-17:00 I was running a couple of cpu-intensive tasks (glxgears plus for brief periods a cpu-intensive script). I wasn't at the computer much during the 17:30-21:00 interval. So it seems like this gets exacerbated by high cpu load. I counted another 12 in the hour following on from the above list. I don't recall seeing these at all under RELENG_6. If they ever did occur they certainly weren't anywhere nearly as prolific. A copy of /var/log/messages from boot until the first disconnection is attached. Any ideas? Wayne --=-txEbhP08aa7EAKj+QoZF--
