I have a problem with a specific USB-keyboard (Cherry G230) during booting NixOS 21.05: It seems that the initrd of NixOS does not recognize the keyboard and disables it:
- The keyboard works in the boot-menu (systemd-boot).
- Then, NixOS initrd starts to boot and seems to disable the keyboard (so e.g. no crypt-password can be entered to decrypt the harddisk).
- Re-connecting the keyboard does not help.
- After NixOS has booted, the keyboard works normally.
A different USB-keyboard works well (both when connected from the beginning and when connected only to enter the crypt-password).
On a different PC with an older NixOS version and grub, the “problematic” keyboard works.
Is there any way to solve this?
maybe relevant dmesg messages::
[...] usb usb2: We don't know the algorithms for LPM for this host, disabling LPM.
[...] usb usb4: We don't know the algorithms for LPM for this host, disabling LPM.
