Nitrokey Start not detected by GNUK toolset (no attribute 'cmd_verify')

[RaymiiOrg]

When trying to load a public key for firmware upgrades the following error occurs:

./tool/gnuk_put_binary_libusb.py -k 0 CB1522E7.bin
Traceback (most recent call last):
  File "./tool/gnuk_put_binary_libusb.py", line 112, in <module>
    main(fileid, is_update, data, passwd)
  File "./tool/gnuk_put_binary_libusb.py", line 52, in main
    gnuk.cmd_verify(BY_ADMIN, passwd)
AttributeError: 'NoneType' object has no attribute 'cmd_verify'

This is on Ubuntu 14.04. GnuPG recognizes the card.

I do have python pyusb 1.0.0 installed as that is in the repo's.

Reading here:

https://github.com/ggkitsas/gnuk/blob/master/NEWS#L55

** Tools and test suite now work with PyUSB 1.0, too.
It only worked with PyUSB 0.4.3, but it works with PyUSB 1.0 too.

Makes me think this is a version issue.

The gnuk source, tag release/1.2.1, also gives the same error. :(

Hi!
Error might show that GNUK tool does not see any supported device. Possibly one has to add vid/pid of NK Start to the tool's source.

Could you run the same using gnuk1.2-regnual-fix branch? I have added there Nitrokey Start's vid/pid.

Closing as fixed. Please reopen if it still occurs.
