neug on ST-link V2: usb errors

[lists at georgweiss.de]

Hi,

I own multiple (also different hw versions) ST-Link V2 dongles and can
flash/run gnuk on them.

However if i try to run them with different versions of neug it will not
be recognized as usb-device (most of the time).

Occassionally if i try hard re-plugging the dongle it will be detected
(also when i reset the STM32F103 chip via shortcut-ing NRST and VSSA as
described in [1])

I tried 5 different dongles (which are running gnuk just fine) so i do
not believe that it's a hardware issue.

I would appreciate any suggestions.



Compiling/Flashing was done in a debian (stretch) docker container:
