We are using driver 12.0.0. for USB key, and the sample software provided in the SDK (GenericWin32Dll\smartdem.c) to test several keys which have an issue. While some keys can be read from the beginning to the end of the test software, several other keys are not found and software reports
- ST_NONE_KEY : Key Not Found.
If we insist with that key, it may show up but it fails in the scrambling test:
- SmartKey found with protocol LOCAL
- Scrambling 3132333435363738 : ST_NONE_KEY : Key Not Found
This issue seems only to affect several keys, but not all of our keys, so it can't be said that is a system specific issue. Even trying the same keys on different hardware gives the same results: faulty keys are faulty on other system at the same way.
The strange thing is that the Smartke Programming Central (SPC) seems to find the faulty key ad it's able to reset it to defaults. Even when reset to defaults, the behavior is the same in the test application. SPC test feature does not report any issue with the faulty key.
Your help would be appreciated.
Thanks in advance and regards,
Stefano
