I'm about to try to interface the source code for this driver to dkms so
that it will get compiled every time I boot from a new kernel, but at
the moment I'm not sure how to tell dkms where to find the source code,
so I'll have to try to investigate that.
"dkms.conf" of rtl8812AU is working example

'modprobe' goes if the device is already plugged in,
otherwise re-plug USB device, and if VID/PID of device and driver match - auto loading kicks in.
I think I have worked out the issue with the flashing light on the
device, it seems to be functioning the same way as the flashing lights
on ethernet pci cards, which from the functionality of the vendor
supplied driver under windows, is not the vendor intended mode of operation.
I now have two issues with the device, one is dkms and the other is
standard networking functionality.
For dkms I have used the rtl8812au dkms.conf as my starting point. My
file is below.
PACKAGE_NAME="rtl8814AU"
PACKAGE_VERSION="4.3.21"
BUILT_MODULE_NAME[0]="8814au"
MAKE="'make' -j3 KVER=${kernelver}"
CLEAN="'make' clean"
DEST_MODULE_LOCATION[0]="/updates/dkms"
AUTOINSTALL="YES"
The driver source code is stored in directory /usr/src/rtl8814AU-4.3.21,
does the version number in the directory name and the 'PACKAGE_VERSION'
in the conf file have to match the internal version number in the driver
for the boot time compile of the driver to work?
I've added the -j3 in the make to get the multi-threaded compile and
I've added the KVER parameter as from my search I did on the net I found
an article relative to an older version of Fedora that said the KVER
parameter must be added to get the driver compiled against the correct
kernel version at kernel install time (they said that without that
parameter the driver would be compiled against the running kernel, not
the newly installed kernel).
With the setup I have if I issue the commands:
sudo dkms build -c /usr/src/rtl8814AU-4.3.21/dkms.conf -m rtl8814AU
-v 4.3.21 and
sudo dkms install -c /usr/src/rtl8814AU-4.3.21/dkms.conf -m
rtl8814AU -v 4.3.21 and
sudo modprobe -v 8814au
they build, install and load the module successfully. I've also found
that the driver does not get loaded and used unless I issue the modprobe
command.
If I issue the command journalctl -o cat -b -u dkms I only get the two
messages below, which are also the only two message I get shown in the
boot display when the driver needs to be compiled for a new kernel.

Started Builds and install new kernel modules through DKMS.
I'm also noticing that when the driver has already been compiled and
installed into the kernel, and I boot my machine, the mounts for my
network connected nas are failing again because the network via this
wireless device is not available. From the flashing of the light on the
device this driver is doing, the network appears to not actually
becoming active until after the display manager is started, and in my
case, I physically log into KDE.
I know that dkms is being run at boot time as I can see the 'job start
timer messages' for dkms, akmod and firewalld, which all seem to be
running in parallel and halt the boot process until they have started,
all disappear and the boot continue.
Is the issue I am seeing with the network expected functionality or is
it an indication there is a timing issue in the driver?
regards,
Steve
