Smart Card Reader rejected IOCTL 0x313520

Hi Michael,

We are using VirtualHere CloudHub (version 4.8.1 on GL-AR300M16) and VirtualHere Client 5.9.3 on Windows with OMNIKEY 3121 Smart Card readers (using the generic Microsoft WUDF drivers) and we've noticed that the following errrors popup multiple times in Windows Event Viewer:

Smart Card Reader 'HID Global OMNIKEY 3x21 Smart Card Reader 0' rejected IOCTL 0x313520: Incorrect function.  If this error persists, your smart card or reader may not be functioning correctly.

Command Header: XX XX XX XX

The event's source is "SmartCard Service" and Event ID is 610.

Smart cards work as expected, however, is there any explanation for these errors? Note that there are no warnings or errors in CloudHub server logs. Perhaps this has nothing to do with VirtualHere?

Thank you!

Marko
