USB Mouse/Keyboard not available when connected through USB Active Extension Cable.

[BERTRAND_7]

Hi,

I have 2 rx4640 with HP-UX B.11.23 (including HWEnable11i_B.11.23.0606.046.

When my USB Mouse/Keyboard are directly connected to the integrity server, every thing works fine and I get the following output from ioscan
Class I H/W Path Driver S/W State H/W Type Description
===============================================================================
OO 0 0/0/2/0 UsbOhci CLAIMED INTERFACE USB OHCI Interface

OO 6 0/0/2/1.0.0 UsbBootMouse CLAIMED DEVICE USB Boot Protocol Mouse
OO 4 0/0/2/2 UsbEhci CLAIMED INTERFACE USB EHCI Interface

For our customer, we have to deport Screen/Keyboard/Mouse in a control room. So we inserted extension cables.
No problem with the screen.
During the EFI boot, the keyboard is fully available : that means that the extension is OK (we also tested the extension cables with a web server without any problems).
Yet, after the boot of the server, we get the following output from the ioscan command :
Class I H/W Path Driver S/W State H/W Type Description

OO 5 0/0/2/2 UsbEhci CLAIMED INTERFACE USB EHCI Interface

The Mouse/Keyboard are not available.

Last year, we had a similar architecture that was working without any trouble with the same extension cables but the result from the ioscan command was a little bit different :

Has anything change for USB on HPUX.

Any help is welcome.

Regards.

Yes, you are right saying about USB change on HPUX. Earlier there used to be a legacy USB driver having modules hid, hub, hcd and usbd which you see in your previous ioscan output.
There is a new USB driver as USB-00 bundle having modules like MouseMUX, UsbBootKeyboard, UsbBootMouse, UsbHub,
UsbMiniBus and UsbOhci as you see in the latest ioscan output.

Check for the patch PHKL_34588 installed on the system.
check out the outout of "ioscan -e" and try running "ioscan -f" .

Take a look at the link below and verify the devices files for USB mouse and keyboard if created.
http://docs.hp.com/en/5991-2710/ch04s07.html

It is also possible to use old legacy USB drivers by removing the new UDB driver modules and loading legacy modules in the kernel.

Hi Sameer,

With the information you provided me, I tried to progress on my problem.

The problem with the USB-00 bundle is that there's no USBHub module.
Sam->Kernel Configuration->Modules (All)
UsbBootKeyboard static static best
UsbBootMouse static static best
UsbBulkOnlyMS unused unused explicit
UsbEhci static static best
UsbHid static static best
UsbMiniBus static static best
UsbOhci static static best
UsbScsiAdaptor unused unused explicit

And in my previous configuration my extension cable is seen as a hub and manage by the 'hub' module from the legacy USB.

The PHKL_34588 is installed on my system and also the PHKL_32629.
ioscan -e and -f are consistant:

OO 5 0/0/2/2 UsbEhci CLAIMED INTERFACE USB EHCI Interface


Finally I remove (swremove) the USB-00 bundle from my system. After reboot it works fine.

Do you know any way to ask HP if there are some evolution planned for the USB-00 in the near future to manage USBHub ?

Thanks for all your suggestions.

Best regards.

Hi Bruno,

You nailed it correctly about UsbHub and this link of May2005 11.23 release notes confirms the same saying that "USB-00 does not support USB hubs and if USB hubs are required, you should revert to the legacy USB driver delivered as a part of the core kernel by uninstalling this product. See the product README notes for more details".

http://docs.hp.com/en/5991-1101/ch04s07.html#cihbdijh

As per the document, the support of USB hubs was taken out in USB-00 ver. C.01.00.00. I think the same applies to latest version C.01.03.01 ( which you might have ) as well.

If you have same USB-00 installed on another server, take a look at the readme using
# swlist -a readme USB-00 | more

You can log a call with HP support and seek their clarification about why USB hub was removed and future enhancements planned for USB-00.
