OpenCT with USB support

[luiszunigacr]

I'm trying to install openct-0.6.20 on CENTOS 7 following these instructions.
On the ./configure step I get this output:
`OpenCT has been configured with the following options:

Version: 0.6.20

`

I'm concerned about the usb support because I need to initialize and use a Nitrokey HSM, which is a USB device.
I set the environment variables LIBUSB_CFLAGS and LIBUSB_LIBS manually, since pkg-config didn't find libusb... In /usr/lib I have libusb-1.0.so.0.1.0 (and a link to this library called libusb-1.0.so.0) and in /usr/include I have usb.h. Any ideas on what could be wrong?

I already installed OpenSC, but it is not recognizing the Nitrokey, I think that is what I need OpenCT for, right?
Thanks in advance!

Hi, As far as I remember libusb is not mandatory in latest versions of openct. You should use openct-tool to list detected devices, make sure it is that this device is actually supported... I do not see a reference in openct, however, I do see reference in pcsc-lite which is more supported these days. Alon

Not to disagree with Alon (everything he says is true), but I also wanted to tell you why configure is not detecting your libusb. openct expects libusb 0.x, which is not common in distributions anymore.

Nitrokey seems to be a CCID device. There are instructions at nitrokey.com for configuring the pcsc libccid driver for nitrokey.
