Use the add_drv(1M) command to make the installed driver usable. Be sure you are user root when you use the add_drv(1M) command.
# add_drv mydriver
The following events take place when you add a driver:
The _info(9E), _init(9E), and attach(9E) entry points are called in that order.
The driver is the most recent module listed by modinfo(1M).
The driver is the most recent module listed in the file /etc/name_to_major.
The file /etc/driver_aliases might be updated. The /etc/driver_aliases file shows which devices are bound to which drivers. If a driver is not listed in the /etc/driver_aliases file, then the OS does not load that driver or attach to that driver. Each line of the /etc/driver_aliases file shows a driver name followed by a device name. You can search this file to determine which driver is managing your device.
The example drivers shown in this book manage pseudo devices. If your driver manages real hardware, then you need to use the –c and –i options on the add_drv(1M) command or the –i option on the update_drv(1M) command. To specify a device class or device ID, you might find the following sites useful. This information also is useful to search the /etc/driver_aliases file to find out whether a device already is supported.

Use the update_drv(1M) command to notify the system about attribute changes to an installed device driver. By default, the update_drv(1M) command reloads the hardware configuration file for the specified driver. Use the prtconf(1M) command to review the current configuration information for a device and driver. For example, the –D option shows which driver manages a particular device. The –P option shows information about pseudo devices.
Use the rem_drv(1M) command to update the system driver configuration files so that the driver is no longer usable. The rem_drv(1M) command does not physically delete driver files. If possible, the rem_drv(1M) command unloads the driver from memory.
