use device ids query

HI

We enable the only device ids which we use and rest everything is disabeled. But at times the devices never work!

Does the device id for a device remain the same or can it change? I see it changing at times!

Does the device id change from pc to pc?

At times for USB Internet Dongles, there are upto 4 device ids from different areas like: CDROM, STORAGE, MODEM. Do i have to enable all of them?

We use deviewer to note the device id before enabling it in the policy.

Our hardware list of device IDs is now huuuuuuge. And there is no way to export it and is a nightmare!

How do you deal with device IDs in your environment?

Thanks
