I have a legacy driver.
In few systems I see my driver entry in Non plug and play section in device
manager.
But few systems doesnt have my driver in plug and play section.
In registry also i dont see Root\LEGACY_MYDRIVER\0000 entry in enum section
of my driver.
ie, HKLMcurrentcontrolset\services\mydriver\enum\
I believe that if only this entry is present in the registry I can see the
driver in non plug and play section in device manager.
who puts this entry in registry.
I see my driver appears in only few systems.
where can I check???

Perhaps the enum entry is added only if the driver has been started.
So if you don't see the registry entry, this driver won't be in dev.
manager as well.

I dont see my driver in device manager's non plug and play section if
Root\LEGACY_MYDRIVER\0000 is not present in the registry entry of my driver.
Again even if I start my driver that entry doesnt appear in registry and I
dont see it in my device manager.

Then, does the driver actually start? does it create some device?

The driver is started and I am sure of that.
another observation is that in longhorn machine I see
Root\ISCSIPRT\0000 in the enum key of my driver.
again I dont see my driver in non plug and play section in longhorn machines
also.
general questions :
1.who creates the enum key and the values inside that key.
2.when does this key actually gets created.
3.why do I see Root\LEGACY_MYDRIVER\0000 entry only in certian machines.
4.what does ISCSIPRT Root\ISCSIPRT\0000 mean.
might be the questions are silly but I am helpless.
any link that explains this might also help me.
Thanks in advance
