I have provided some testdata in the hopes of making debugging this issue easier:

cardreader USB-C:
USB\VID_096E&PID_0624&REV_0225
Test : OK (very fast readout)

cardreader USB-C:
USB\VID_096E&PID_0624&REV_0222
Test : OK (fast readout)

cardreader Micro USB:
USB\VID_096E&PID_0624&REV_0112
Test : NOK (uncatchable app crash with 2.0.1.3 | slower readout but ok on older version 1.0.9.6)

cardreader Micro USB:
USB\VID_096E&PID_0624&REV_0112
Test : NOK (uncatchable app crash with 2.0.1.3 | slower readout but ok on older version 1.0.9.6)

All of the older cardreaders type micro usb with product & fw PID_0624&REV_0112 end up in an app crash while ignoring try catches in xamarin.android & pcl xamarin (seems like an uncatchable internal lib error):

Our customers with an older cardreader get this issue only when using the newest driver FTReaderAPI_2.0.1.3.jar, libFTReaderPCSC_2.0.1.3.so

These tests were done on Android 13. We are also open to try out experimental builds

I think this can be linked and be the same problem than my issue : #45

Did you manage to solve this issue? I have the same issue...

Anioz commented

@mjiricek We solved it for our clients by rolling back to 1.0.9.6 for now which works with all models without the listed crash.

Thank you for your reply. This isn't solution for me because I also have an issue with 1.0.9.6
