How to identify the USB device repeatly being reset in syslog?
 
Hi All,
I noticed there're lots of "usb 3-1: reset low speed USB device using uhci_hcd and address 2" warnings in two of our server's syslog. They occur roughly every 20min. The server is a Dell R710 with CentOS 5.4 X86_64 installed. I suspect it's the virtual CD device of the iDrac6 but not sure. How Can I identify which USB device triggering these warning? The related syslog is as following:
Code:
