Not all Keyboards recognized for entering passphrase on boot

[cmdic]

Hi,

I have to Logitech keyboards, both work fine in BIOS and after booting.

But only one of those keyboards works for entering my passphrase:

dmesg-log working keyboard:

Do I have to add a Kernel-Module or something?

Both keyboards are almost the same. The working one is the precursor of the not working one.

The only difference I can notice is that the working one is registered as: hiddev0, the other one isn't.

Any ideas?

cmdic,

Logitech Unifying Device. has its own kernel module and it doesn't seem to be loading.

You need

Code: Select all

  │ │             <M> Logitech devices                                                                │ │  
  │ │             <M>   Logitech Unifying receivers full support

in your kernel.

Hi,

thanks!

In my kernel config the drivers were already marked as Modules, so I installed them in the kernel.

Not sure whether that was really necessary or if I could have loaded it before entering my passphrase.

Anyway I compiled them in the kernel and it works!
