Kobo Libra 2: no UI, and log says "failed to get kobo info: unknown device"

[jucor]

Dear @shermp

Thanks for a very promising tool! I just bought a Kobo Libra 2, and sadly the UI is not showing. I get the message "Running precautionary library rescan", then just a window saying "Finished", and that's it.

I am using Kobo LIbra 2, Model N418, FCC ID: NOIKBN418, IC: 8857A-KBN418, with Firmware 4.21.19086 (2adb3f45ad, 1/20/22).
I am using Kobo-UNCaGED release 0.5.2.

I checked ku.log , attached.

It looks like

Kobo-UNCaGED/kobo-uncaged/device/device.go

Line 84 in 46c2309

if err = k.getKoboInfo(); err != nil {

is failing and thus exiting.
How can I help? I was looking for a debug mode that would print the return of kobo.DeviceByID obtained in

Kobo-UNCaGED/kobo-uncaged/device/device.go

Line 308 in 46c2309

if dev, ok := kobo.DeviceByID(id); ok {

, but no dice.

Happy to help debug this any way I can!

Ah, looks like the problem is in the kobo-utils package not yet knowing Libra 2: pgaskin/koboutils#5

[jucor]

I've sent a pull request upstream pgaskin/koboutils#7 -- any eyes on it are very welcome @shermp please :) since I'm new to Go and to Kobo.

Thank you for prodding me to do some updates. It's been a while...

I've finally got off my posterior and implemented a GH workflow to build KU. It helps that the fine Koreader folks decided to release binary koxtoolchain packages, which was a massive help.

(Untested) builds are now available from the Actions tab. Next job will be to update koboutils

@jucor Builds should now be available in the Actions tab that work on the Libra 2. Eg: https://github.com/shermp/Kobo-UNCaGED/suites/5549544789/artifacts/178880020

[jucor]

Woohoo, it works on the Libra 2 ! Thanks a lot for your reactivity and for the great tool :)

[shermp]

@jucor no worries.

I must admit, I've been ignoring KU for quite a while. I haven't really worked on any Kobo stuff for a few months (except for helping with the FW 4.31 patches).

I suppose I should make a new release sometime...

[jucor]

This is something you're doing on your free time, noone has any right to demand you maintain it like clockwork! A release would likely be helpful to buyers of new kobos, of course - I've found KU so easier than having to root around for the right cable :)
