how to find USB device is enabled or not?

[R.K. #]

The HP-UX 11.23 USB driver can work for mice and keyboards.

As far as I know, it doesn't support any kind of storage devices.

Also have a look here:

[SoorajCleris]

Hi,

It supports DVD and CD.
And in EFI shell you can access usb thumb drive also.

Depending on the OS version it detects like

with USB 1.1 driver -- it will detect as /dev/devicefilesystem.....
with USB 2.0 driver -- it will detect as normal cxtxdx

how to bring it to unclaimed state?

[Lijeesh N G_1]

Hi,

This is the Software state of a device,If the proper drivers are loaded,
the state of the device will come to the CLAIMED state,
Below is the details of states,

CLAIMED==>software bound successfully
UNCLAIMED==>no associated software found
DIFF_HW==>software found does not match the associated software
NO_HW==>the hardware at this address is no longer responding
ERROR==>the hardware at this address is responding but is in an error state
SCAN==>node locked, try again later

LIJEESH N G

[SoorajCleris]

Hi,

You will not be able to make it UNCLAIMED , since the disk is detected. You can remove the device file of the cdrom from the /dev/ directory using rmsf.

I will not suggest you to do this, and I dont know why at all you want to do this with an HP-UX server.

The device filecan be created again by a root user.

No way!




What is your goal to "enable/disable" or whatever you call this?

[fizan]

to disable the cd-rom drive ..

[Torsten.]

Now we already discuss in up to three different threads ... :-(

Why do you want to disable?
