v.1.2-beta.4 not cooperating with VM/Virtualbox (Windows'es 7/10 do not detect the device)

[szszszsz]

on Win7, Win10 and Ubuntu 17.10 App 1.1 is working fine on Virtualbox, but not 1.2-beta.4 What I also realized is that using App 1.1 on Ubuntu 17.10, closing it, installing App 1.2, starting without ejecting the Nitrokey works fine until you disconnect once.

It seems like it has something to do with scdaemon. At least on Ubuntu 17.10 it is working now after installing scdaemon. If this is true, it is probably a good idea to make scdaemon a dependency of nitrokey-app.
Although it is mentioned as needed for GnuPG on website, it is not marked as needed for App to work.

Issue with Windows is resolved now (pending fix being added to repository).
About Ubuntu 17.10 I got confused - is this still occurring? App is not using scdaemon - it communicates directly with libhidapi and libusb. Could you try to run the App with it (scdaemon) removed (and its dependencies)?

GnuPG needs scdaemon to work with OpenPGP Card. After removing scdaemon, App recognizes the Nitrokey only if it was recognized before when scdaemon was yet installed. When I disconnect the Nitrokey and try again, it will not get recognized anymore.

Tried with Pro and OPC2 and Storage with OPC3.

The App may not need scdaemon directly, but as it make use of GnuPG functions (or not?) it may depend on it?

This may is not a VM/Virtualbox issue at all 🤔 Will try on "real" Ubuntu 17.10 (really 😉).

I see. Could you briefly list scdaemon dependencies on 17.10?
Perhaps some of them should be included in App's deps too.
Edit: 17.04 shows:

$ apt-cache show scdaemon | grep Depends
Depends: gnupg-agent (= 2.1.15-1ubuntu7), libassuan0 (>= 2.2.0), libc6 (>= 2.15), libgcrypt20 (>= 1.7.0), libgpg-error0 (>= 1.14), libksba8 (>= 1.3.4), libnpth0 (>= 0.90), libusb-1.0-0 (>= 2:1.0.9)

App is not connected to GnuPG in any way; uses libhidapi/libusb only.

I will look at it later. But I can confirm: "real" Ubuntu 17.10 is the same behavior -> uninstalling scdaemon only removes ability to detect Nitrokey if not detected earlier.

Moving scdaemon-related issue to #310

This will be closed on merging Windows-related fix.
