I started lately reading some articles about the kernel space and especially about device drivers. So I was wondering are there some minimal requirements for a device in order to make it easy to write a device driver for it?

But it does meet your desire to "make it easy".)
Some sort of testing mode, or device simulator, which a driver for a burglar alarm, a way of triggering the device to send an alert from a window sensor.

I have an EC2 instance with "instance store" device as a root device. Now, I would like to attach an EBS volume to that same instance, only that I want it to be the root device. Is that possible? What happens to the instance store device in such case?...

You don't have to have security set up (no pin code) so you could have a bluetooth device have to connect/pair.
If you know the MAC address of a bluetooth device and it is connectable you can talk to it directly.

If you edit lvm.conf and add something like
filter = [ "a/md/"... .
Basically, LVM scans all the block devices in your system and is finding /dev/sdX before /dev/mdX.

Is that something specific to your device driver?
I'd guess it is a problem in the driver, check the open function.
Are you the ".ko" extension.
Mknod doesn't care if there is an device corresponding to the given major/minor numbers.
