.SH "DESCRIPTION"
.PP
Drivers for hot pluggable/unpluggable devices (such as USB or Firewire) can set this
flag at the moment when the device gets unplugged and turn it of when it becomes
available again. By defalt the device is available. Drivers for noh-pluggable devices 
(PCI, ISA) must not care about this flag.
.PP
This information is used to prevent OSS from opening a device when it's not present. However this doesn't guarantee that no driver calls are made. The driver must check itself
if the device is really present before doing any operations.
