This manual page was adopted from Nx 1.6 and modified for Fx by An Hiten Pandya Aq [email protected] .BUGS
The PCM framework in Fx , as of this writing, does not handle device un-registrations in a properly abstracted manner, i.e., a detach request is refused by the PCM framework if the device is in use. It is necessary to allow the device un-registration to complete successfully, otherwise the PCM layer will panic.
