Reading the MIB, and maybe I'm missing something here, it doesn't
seem like this OID is optional. In my interpretation, if the hook
is missing, the value returned should be 'unknown(1)'.

What I am seeing is that on my SuSE Intel box:
* Rows with hrDeviceTypes of hrDevicePrinter & hrDeviceNetwork
show valid hrDeviceStatus & hrDeviceErrors
* Don't have a row with an hrDeviceType of hrDeviceProcessor
(maybe the Intel box is not playing nice when it comes to
divulging processor info)
On my SuSE RISC box:
* Row with hrDeviceType of hrDevicePrinter has row for
hrDeviceStatus & hrDeviceErrors
* Rows with hrDeviceType of hrDeviceNetwork do not show any
rows for hrDeviceStatus & hrDeviceErrors (possibly no hooks,
but seems like a bug)
* Row with hrDeviceType of hrDeviceProcessor does not have
a corresponding row for hrDeviceStatus (seems like bug as per
your comments above)
In re-reading my note, it sounds a bit confusing even though I
know what's going on, so I am cutting and pasting the hrDevice
table dumps here for clarification.
Thanks for any help on this matter.
