You lose the remote KVMS keyboard and/or mouse connection to the system when rebooting the Solaris Operating System (Solaris OS). There is a USB compatibility issue between the remote KVMS virtual keyboard and mouse feature and the Solaris OS, which although unlikely, can cause the remote KVMS virtual keyboard and/or mouse to become unresponsive following a warm reboot of Solaris. This problem does not occur on a power-on boot.
From Solaris, you must reset the USB port connected to the virtual keyboard and mouse. To reset the USB port, perform this step:
cfgadm -x usb_reset usb0/1
This command will reset the port. If that action does not correct the problem, reboot the host again or restart the service processor.
