Improvements to the installation procedure #3

Thanks a lot for providing this module!

I just found that something was missing to make the use of the module permanent - here is an extended list of commands:

make
sudo make install
sudo depmod -A
sudo modprobe xmm7360_usb
echo xmm7360_usb | sudo tee -a /etc/modules

I've used an alias to make udev load it for me, but I used the alias specific to my computer just in case it causes problems for anyone, I guess I could make it more generic.

Just out of curiosity, what does lspci -nnvd 8086:7360 say on your computer?

lspci -nnvd 8086:7360 yields here:

3b:00.0 Wireless controller [0d40]: Intel Corporation Device [8086:7360] (rev ff) (prog-if ff)
    !!! Unknown header type 7f

P53 hardware is different I think - Sat Nov 9 18:26:45 2019] pci 0000:53:00.0: runtime PM trying to activate child device 0000:53:00.0 but parent (0000:00:1c.6) is not active [Sat Nov 9 18:26:45 2019] pci 0000:53:00.0: PME# supported from D0 D3hot D3cold [Sat Nov 9 18:26:45 2019] pci 0000:53:00.0: Adding to iommu group 10 [Sat Nov 9 18:26:45 2019] pci 0000:53:00.0: DMAR: Device uses a private identity domain.

Note, the Modem complains parent not active, since of course, we broke the link.

Not sure why I'm still not getting a USB device...

Actually I was thinking about lspci -nnvd 8086:7360 after unloading the module first, otherwise it doesn't give much info. But I guess I could make the module alias itself to everything 8086:7360 to avoid the need to update /etc/modules

DKMS - need to build properly for "UEFI/LockDown" 1) Make sure the source is in /usr/src/$MODULE_NAME-$MODULE_VERSION 2) cd /var/lib/dkms 3) dkms add $MODULE_NAME/$MODULE_VERSION 4) dkms build $MODULE_NAME/$MODULE_VERSION 5) dkms intall $MODULE_NAME/$MODULE_VERSION

Example: cat /usr/src/xmm7360_usb-1.0/dkms.conf

Here's the dkms.conf for "xmm7360_usb" - it's really generic.

MAKE="make -C./ KERNELDIR=/lib/modules/${kernelver}/build" CLEAN="make -C./ clean" BUILT_MODULE_NAME=xmm7360_usb BUILT_MODULE_LOCATION=./ PACKAGE_NAME=xmm7360_usb PACKAGE_VERSION=1.0 REMAKE_INITRD=no DEST_MODULE_LOCATION="/kernel/drivers/misc" ATUOINSTALL="yes"

@juhovh, makes sense. Here it is:
