When a reader works in the current version uDemo (USDK Demo) but not in the Augusta SDK Demo, it may be the .dll files in the SDK Demo are outdated.
The SDK is comprised of IDTechSDK.dll, and then the device libraries (Augusta_xxx.dll). If USDK demo is working better, you should use those libraries instead. So this means where ever you have installed your USDK demo, in that folder, you can retrieve the latest IDTechSDK.dll, and also all the latest Augusta_xxx.dll libraries (in the lib folder of USDK folder). And then you can use them to REPLACE the same library files in your Augusta demo folder.
