Smells like a usual autosuspend issue.  Adding Oliver to Cc.

No,

this is unlikely to be autosuspend, as then we have absolutely no explanation why it fails only wen the system suspends. This looks like the keyboard is sharing a firmware bug where it cannot operate without enabling remote wakeup. Patch coming up.

Indeed, this works with another keyboard.

I will try to look for an updated firmware.

Does the hardware ID really correspond to an Apple product?

I am pretty sure this is not an Apple keyboard.

While lsusb shows 

Bus 003 Device 032: ID 05ac:024f Apple, Inc. Aluminium Keyboard (ANSI)

lshw shows

The software for changing settings on Royal Kludge keyboards identifies it as RK-G68 

With this brand name I suppose it's unreasonable to expect smooth operation.

> With this brand name I suppose it's unreasonable to expect smooth operation.

The ID says Apple. Now you have a point in saying that they are highjacking an ID and we should not penalize true Apple products. However, unless the quirk works, the point is moot.

No change with the patch applied.

With two keyboards connected in suspend

- broken keyboard flashes backlight every 10s or so, working is dark
- pressing key on broken keyboard does nothing, working keyboard wakes system
- after resume working keyboard has correct keymap, broken keyboard has default keymap (there is no way to permanently set keymap in openSUSE I am aware of)

No fix has been found.

Clearly this is a problem with specific piece of hardware, let it RIP.
