Hi Guys,

i found a way around the problem myself. Should have read the available ressources and forum posts better. For future reference and for anyone with the same problem.

- Add the neccessary lines from [https://www.nitrokey.com/documentation/installation#p:nitrokey-pro&os:linux](https://www.nitrokey.com/documentation/installation#p:nitrokey-pro&os:linux) to the file /lib64/pcsc/drivers/ifd-ccid.bundle/Contents/Info.plist

- Install the File [40-nitrokey.rules](https://www.nitrokey.com/sites/default/files/40-nitrokey.rules) unter /etc/udev/rules.d

- Restart udev or simply reboot.

Afterwards initialization and usage of the Nitrokey HSM is possible.

Basically everything has been said already in the forum post “[Nitrokey Pro installation under RHEL7/CentOS7](https://support.nitrokey.com/t/nitrokey-pro-installation-under-rhel7-centos7/194)” (thanks to user jwildeboer, can´t link to it because i can only put 2 links in my post…), only installation of the udev rules file was missing there. I guess this is done with installing the nitrokey app (which i don´t use with the Nitrokey HSM).

Suggestion: For a better user experience, some official step by step tutorials to get things running would be really nice.
