Unfortunately yes, we need actual device tests:
- this series enable 0x2121 on all of those devices (is it correct?)
- we are not shielded from a FW error and something that goes wrong
when enabling one of those mice with hid-logitech-hidpp.c. All of
those mice works fine with hid-generic, and if we oversee one tiny
bit, we'll regress for no good reasons.
