USB devices are not accessible even if ‘Full control’ for USB Port is configured for all users / devices are white listed for all users.
Comments
The issue may indicate that when anti-keylogger functionality is active, DeviceLock may treat some devices as keyloggers, when they are actually not, and block access to them.
Recommendations
1. Start DeviceLock Management Console, connect to the problem computer, and enter ‘Service Options’-> ‘Anti-keylogger’.
