one more reference on the subject

@David: I remember seing something about PnP in HAL. Is there any
*serial* PnP support, which is the thing that interest us?
@Arjen: would you like to relaunch a "call to test" on upsuser with a
pnp_probe program? The aim would be to collect the more PnP UPS data,
but only if it can be useful in the HAL context.
