Solaar is a Linux manager for many Logitech keyboards, mice, and other devices that connect wirelessly to a Unifying, Bolt, Lightspeed or Nano receiver as well as many Logitech devices that connect via a USB cable or Bluetooth. Solaar is not a device driver and responds only to special messages from devices that are otherwise ignored by the Linux input system.
I hope one day theres something similar to this, but for 8bitdo.
I have an 8bitdo keyboard, and in order to map my buttons, I need to boot up a windows 10 hard drive, do my one time edits, save them to the keyboard, and THEN I can turn off the pc, swap back to my ZorinOS hard drive, and THEN I can go about as normal.
And if for some reason somethings wrong, or didn't take, I'd have to repeat the whole process all over again.
All because the keyboard manager doesn't work on linux. But it's not logitech.
Wooting keyboards are also really nice, and are configured through a web interface. It's also a Dutch company, so if you want to buy European it's definitely a good choice :)
I have a Flydigi gamepad and I can use a virtual machine with tiny11 to change the configuration. The connection isn't super stable but for the few times I have to do it, it works.
