Issue description

SHARE partition empty + volume buttons not working + wifi dongle not detected

Detailed reproduction steps

burned knulli with ETCHER
booted successfully with 32gb micro sd card and let system on default configuration

Details of any attempts to fix this yourself

hello,

first of all, thanks for your work :)

i am currently testing the last version available on github and there is some bugs / issues

about SHARE partition
Knulli created partition but no folders - empty partition
Is there a way to create folders structure and be able to add roms ?

i took a look on wiki and see about userdata
on my case, userdata folder is empty

i also tested external USB (sandhis 256gb mini stick) and not detected
i formatted stick on EXFAT but still not detected

about EMULATORS section
on Powkiddy A12, PPSSPP is visible and i think it will be recommended to delete it
no access to RETROARCH and recommend to be the only one to use for CPS, Neogeo, Cave, Arcade roms and 8/16 bits roms

wifi dongle
i usually use Batocera v35 and this version is able to detect my wifi dongle
on the last version of Knulli, my wifi dongle is not detected
i made test with the DTB from Batocera v35 and bartop stay on black screen

Volume buttons
Volume up and Volume down not working

many thanks for your help and time :)

About the Wi-Fi Dongle issue:

The Wifi USB Dongle can be solved by this sequence: Enable Wifi, Disable Wifi, Enable Wifi.
Once network is enabled, you can SSH to the system.

About the SHARE partition issue:

I solved (more a temporary workaround) the issue by formatting the partition with ext4 filesystem. I edited /etc/fstab (after putting the root filesystem in rw mode with: mount /dev/mmcblk0p2 / -o remount,rw) and added this line:
/dev/mmcblk0p4 /userdata ext4 defaults 0 0
Put back the root filesystem in read-only mode with: mount /dev/mmcblk0p2 / -o remount,ro

Them, just copy the structure of of the folders from this location to /userdata:
cp -R /usr/share/knulli/datainit/* /userdata/

It seems the init scripts are formatting the SHARE partition with exfat filesystem, but there is no kernel support to mount exfat.

Once /userdata is mounted to the SHARE partition, every change will be kept (saved).

About Volume-UP and Volume-DOWN keys not working:

While the root filesystem is in read/write mode, edit this file (with the nano command) and paste the 2 lines below:
nano /etc/triggerhappy/triggers.d/multimedia_keys_GameSimulatorBoard.conf

KEY_VOLUMEUP 1               /usr/bin/knulli-audio setSystemVolume +5
KEY_VOLUMEDOWN 1             /usr/bin/knulli-audio setSystemVolume -5
