I’ve recently installed CentOS / RHEL 6.x on the server. I’m getting the following messages in /var/log/messages file logged frequently :

Oct 13 14:00:20 server1 kernel: usb 1-7: reset high speed USB device using ehci_hcd and address 2
Oct 13 14:05:57 server1 kernel: usb 1-7: reset high speed USB device using ehci_hcd and address 2
Oct 13 14:09:18 server1 kernel: usb 1-7: reset high speed USB device using ehci_hcd and address 2
Oct 13 14:11:42 server1 kernel: usb 1-7: reset high speed USB device using ehci_hcd and address 2
Oct 13 14:11:49 server1 kernel: usb 1-7: reset high speed USB device using ehci_hcd and address 2

How do I solve this problem?

Q. My Ethernet aliases are randomly switched and they are bound to the wrong interface. My eth0 became eth1 and eth1 become eth0. This is causing all sort of trouble for services and firewall configurations. How do I swap back and make sure Ethernet aliases works correctly under CentOS Linux server?
