Hi, Just experienced this in 2.6.32-5-openvz-amd64 (Debian 2.6.32-30). I think this should be reassigned to the linux-2.6 package as it's a bug in the Linux USB drivers rather than apcupsd.
Usually I see the stream of the "control queue full" errors first, but this time apcupsd hung very soon after boot: [ 2161.688204] INFO: task apcupsd:21604 blocked for more than 120 seconds. [ 2161.695216] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

Before the machine's last reboot, apcuspd+usbhid had worked fine for 4 days. It's quite spontaneous and I see no pattern to it.
