After the weekly reboot, I am seeing the following two errors in the event logs and not sure what they mean.
The device 'iDRAC SECUPD USB Device' (USBSTOR\Disk&Ven_iDRAC&Prod_SECUPD&Rev_0323\20080519-1&0) disappeared from the system without first being prepared for removal.
The device 'USB Mass Storage Device' (USB\VID_0624&PID_0249\20080519-1) disappeared from the system without first being prepared for removal.
It appears that the server isn't recognizing these two USB devices, but not sure how to resolve?
