Advisory: Red Hat Enterprise Linux 6 - Message Log Fills With "Kernel:uhci_hcd 0000:0x:00.x: Controller Not Stopped Yet!" Messages on HP ProLiant Servers With Integrated Lights-Out 4 (iLO 4) and Running hp-snmp-agents Version 9.30 Through Version 9.4x
http://h20564.www2.hp.com/portal/site/hpsc/public/kb/docDisplay/?docId=emr_na-c03928238
In Red Hat Enterprise Linux 6, when lsusb -v is run to poll the server resources, a message is posted to the syslog. The cmastdeqd has a script that runs and executes the command "lsusb -v -s". This agent polls the server every thirty seconds by default and thus the message is posted to the syslog at that rate. After cmastdeqd is stopped, if "lsusb -v" is manually executed at command-line the message will still post to syslog until Red Hat update is applied.
