So, I've got Manjaro ARM both on a Raspberry Pi 4 (kernel 5.4.51) and on the Odroid N2 (5.7.10).
Both up-to-date on stable.
On the Odroid N2 my kobo touch ereader is not responding / detected / seen. Not in lsusb, not in dmesg, not in journalctl -f. When I plug the kobo reader in, it is as if it is not connected at all. Tried it on a couple of USB ports, where both keyboard and mouse works.
On the Raspberry Pi same kobo touch ereader, same cable, it all automatically works.
The kobo reader is not very recent, so won't be usb3. The N2 ports are usb 3.
Could it be that the Odroid N2 kernel is missing some usb storage drivers / modules?
Is there an additional service I should enable and start?
