Connect via SSH and run the command:

dmesg | egrep –color usb

Check the output. If you see any of the errors listed below, you have the issue with your USB key:

usb 1-1: new high speed USB device using ehci_hcd and address 2
usb 1-1: device not accepting address 2, error -110

1. Connect a USB keyboard to PBX
2. Reboot or power off/power on the PBX
