I have been working with wireless keyboard and mouses from several manufacturers, but I have been trying to use the logitech’s MK540 and MK235 under SuSe.
But there is some turmoil there, these devices uses the unifying receiver (the others keyboards come with Bluetooth so it’s rather easy to pair and connect); at first there was nothing to configurate (dialog window), installed Solaar, from the git and Suse’s repo. But there weren’t detected.
Went to check what does dmesg say’s and at the tail it says
xhci_hcd 0000:04:00.0: WARNING: Host System Error
I remembered then , a couple of years ago, something likely was happening over Arch, and the workaround was to enable a value directly in the device subsystem tree
echo -n "0000:00:14.0" /sys/bus/pci/drivers/xhci_hcd/unbind
and bind too. This enabled the keyboard as the mouse to work together for 10 seconds (more or less), then it becomed freezed, checked dmesg again, and this time is marking
[ Bluetooth: RFCOMM TTY layer initialized
socket layer initialized
[Bluetooth: RFCOMM ver 1.11
logitech-hidpp-device 0003:046D:4054.0005: HID++ 4.5 device connected.
sd 0:0:0:0: [sda] Stopping disk
xhci_hcd 0000:04:00.3: WARNING: Host System Error
And that’s it, it is unable to be usebeyond the boot, and then it suddenly stops working until the system reboots.
Updated to the last kernel and the microcode/firmware. But it does change.
It’s rather obnoxious, since there is another devices like the k400+ of the same vendor, that is detected,configurated and running with the solaar program, no problem at all.
I’t is not so new models, they’re been around since 2016/2017.
Thanks in advance.
