sys-usb issues ; yubikey, etc

[Myna]

well I just about locked myself out of the system, by doing :


Enable sys-usb:

qubesctl top.enable qvm.sys-usb

Apply the configuration:

qubesctl state.highstate

It said like 3/5 successful, Having no idea how to undo this, and
fearing meltdown, just rebooted, not to my unsurpise, I could not logon
to the LVR decrypt screen, as keyboard disabled, went into UEFI, enabled
PS2 simulator, and luckily I had bought a PS2 -> USB adapter, and the
mini ITX has 1 PS2 slot, however still would not POST, so had to plug in
a 2nd USB keyboard, it then POSTed, and I used the PS2-USB keyboard to
login, however,

1) am I going to have to do this everytime?



I answered 'yes' not 'yes to all' for the USB mouse to use sys-usb,
but I also have a USB yubikey,


2) how do I get sys-USB to allow the Yubi key ??


I noticed all my postings are going up the original Thread, see where
this one lands ....:)

I do see https://github.com/adubois/qubes-app-linux-yubikey

however, I think compiling it might be over my head. Can I just
shutdown sys-usb and operate without it again ? I definitely need the
yubikey to work, but my other security needs ......

ya I think you might not be able to do both, either one or the other. but I'm not 100% sure.

curious, why in an AppVM in the software gui I am offered to upgrade
Fedora 25 to, however in the QVM there is no such offer, nor does the
software gui suggest Fedora 25 , seems curious, I suppose I'm to just
ignore whatever is offered in a AppVM based on Fed23?

[cooloutac]

what do you mean by offered? I've never seen any notice about fedora 25 when using fedora 24 on my system.

Did the same thing to my machine once. Switched over to a PS/2 keyboard afterwards. Most mechanical keyboards work in PS/2 mode when connected via USB>PS/2 adapter to a PS/2 port on the motherboard.
