USB FLASH DRIVE SUPPORT

[john guardian]

Does HP 11i-v2/3 support USB Flash Drive insertion, mounting, read+write?

If not directly supported, is it IN-directly supported?

If either of the above is true, can USB Flash Drive use be disabled by deletion of packages, filesets. etc? If so, please be specific.

Thx.

Hi,

11iv2:
supported flash drives supported is short.
"Update to USB Driver Support on HPUX 11iv2":

11iv3:
most available flash drives should function correctly

The above links are great for someone wanting to enable the USB write capability of FLASH Drives and DVD/CD media... but I need to do the exact opposite. I need to DISABLE this functionality.

How would I DISABLE write capability to these devices?

Hi John,

just re-read the instructions - there are all hints:

11iv2: check if USB-00 or patch PHKL_39269 is installed (swlist ...)
If yes - swremove it.

11iv3: check if USB-00 or USB-02 or patch PHKL_39820 is installed (swlist ...)
If yes - swremove it.
With VM, also check for patch PHSS_38566 and PHSS_38567.

If you can disable it as root, root can enable it again.

Other users cannot mount it or use it in another way.

Disablement is preferable to removal. How?

Also, I was viewing bundle/product info w/swremove and saw:

For bundle USB-00:
USB-CORE
-EHCI
-OHCI
-TRANS

Drilling down one level, the list then looks like:

BLKONLY-MS
BOOT-KBD
BOOT-MOUSE
CORE-OOC
DEVFS
KBD-MUX
OOC-SVCS
OO-CDIO
SYSPREP
USB-CORE
-EHCI
-OHCI
-TRANS

Can a select few from the immediate above list (only) be safely removed in order to disable the CD/DVD and FLASH?

Thx.

In other words - IMHO you don't need to do anything, because no normal user can mount it anyway.

Hi.

Still need to know if deleting

BLKONLY-MS & OO-CDIO

will effectively remove CD/DVD and Flash Drive Functionality? Or is BLKONLY-MS only for "other" types of mass storage?

Also, what about floppies on HP-UX. I haven't seen any systems come thru with them in years?

Thx.

You should test it ...
Do you have a test server?

After re-reading the link:
For 11iv2:
patch PHKL_39269 is installed with USB-00 version D.
All USB-00 before v.D will not have the patch and so the system doesn't support USB Flash Drive.

I think, for more certainty you have to ask HP for help.

Hi,

if you have a test server, try to disable (cf kcmodule(1M)) following kernel modules:
- UsbBootKeyboard
- UsbBootMouse
- UsbBulkOnlyMS
- UsbEhci
- UsbHid
- UsbMiniBus
- UsbOhci
- UsbScsiAdaptor
- usbd
- ehci
