The following applications crash by accesses violation when more than 10 devices are recognized:
- VKB T-Link
- VKB Button Tester
- VKB Joy Tester
That doesn't mean that the number of connected devices cant be more than 10.
It crashes only if the number of devices listed by these applications is more than 10.
You can verify the number of of devices these application can recognize by using running joy.cpl command in windows.
If the list there is longer than 10, then the application crashes.
You can see the entire list of devices by using the VKB Show HID application and you can verify that there are more than 10 devices connected.
You can plug more than 10 devices as long as these new devices are not listed/recognized in joy.cpl
Unplugging any random device to 10 or less will make the applications work again.
