Need to downgrade (or upgrade?) Logitech K375s firmware (or get access to newer firmware)
I have a Logitech K375s keyboard that I'm using on Ubuntu 18.04 systems. The following are screenshots from Solaar on my system:
The current MPK 03.04.B0014 firmware for my keyboard seems to have a bug.
The keyboard goes into a suspend or sleep mode after its untouched for a short while, which I am sure preserves the battery life. When it is touched again, it "wakes up".
On my Logitech K375s with the MPK 03.04.B0014 firmware, there's a string of gibberish that flies out of the keyboard every time it "wakes up" from this light, and otherwise perfectly functional, sleep. I've tried swapping the keyboard mode -- to iOS mode (by pressing Fn-I for about seven seconds), to MacOS mode (by pressing Fn-O for about seven seconds), and to Windows/Android mode (by pressing Fn-P for about seven seconds) -- and none of those modes is without this issue. In fact, every time a switch modes, a new set of garbage is randomly spewed by the keyboard (albeit, each mode seems to use a slightly different set of garbage characters. I suppose there is a small chance my keyboard was physically damaged in some way, but it's working perfectly in all other ways. And the keyboard has been doing this since I purchased it, IIRC.
I like this keyboard in every other way. I believe it's too late to return it. I really don't WANT to replace it.
Can I either downgrade to the MPK 03.02.B0009 firmware available on LVFS already -or- can newer firmware that fixes this problem be uploaded to LVFS? I've tried with Ubuntu 18.04 systems, running this version of fwupd:
user@xubuntu:~$ sudo fwupdmgr --version
client version: 1.2.10
compile-time dependency versions
gusb: 0.2.11
efivar: 34
daemon version: 1.2.10
user@xubuntu:~$
When I run fwupdmgr get-devices, the Unifying Receiver shows up, but not the keyboard device.
user@xubuntu:~$ sudo fwupdmgr --allow-older get-devices

How would I force the downgrade? Or will there be an upgrade? I'm REALLY hoping there's a solution. You have no idea how badly this interferes with writing documents, gaming... virtually everything worthwhile I do on this system. And it's otherwise SUCH a great device...
This seems related to, but unique from, long-expired fwupd/fwupd issue #449; I also submitted fwupd/fwupd issue #2044 in relation to this. Please let me know what can be done! Thanks.
Also opened Logitech Ticket #2925522, if you guys can coordinate with the consumer support people...
I forced my laptop to upgrade to Ubuntu 20.04 and now had access to this version of fwupdmgr:
user@xubuntu:~$ sudo fwupdmgr --version
client version: 1.3.9
compile-time dependency versions
gusb: 0.3.4
efivar: 37
daemon version: 1.3.9
user@xubuntu:~$
I was able to get a bit farther. It would not let me downlevel the firmware on this keyboard, though I was able to see the device:
user@xubuntu:~$ sudo fwupdmgr --show-all-devices get-devices

Is there any chance that K375s firmware will be released via this channel again?
