usb problem

[lin.chen]

I found that the usb status of ioscan is unclaimed
root(rt1)# ioscan -fnC usb
Class I H/W Path Driver S/W State H/W Type Description
=================================================================
usb 0 0/0/2/0 hcd UNCLAIMED UNKNOWN USB OHCI Interface
usb 1 0/0/2/1 hcd UNCLAIMED UNKNOWN USB OHCI Interface

the usb device is not found in EFI,so i can not use mouse and keyboard
in SAM kernel configration,moduls,the state of usb device is unused,but ican not change the state to static.
i wonder need I replace the IO base board!

Hi Lin,

What is the model of the server ? Have you checked for the drivers ? Was it working earlier ?

in SAM?

Hi,

Via sam follow the below steps to check the drivers..

1.SAM main menu
2.Select Pdweb Cards and Devices (character mode)
3. Select i - I/O Tree: View all devices on the system

Here u can see the Pheripheral Devices connected out of which the USB is one..select the USB at the above hardware path which shows unclaimed.
