License dongle "disconnects" randomly ESXi
I have seen a problem on several virtualized systems where the license dongle is added as an "USB Device" to the Aspect Server.
The issue is that occasionally the license dongle is disconnected from windows and hence 800xA give a warning of a missing/failed HW key. Can be weeks and months between each time, there does not seem to be any regular interval.
Issue seen on 800xA SV5.1 FP3, SV5.1 FP4, SV6.0 and ESXi 5.0, 5,1 and 5,5.
Exactly how this is happening I do not know, but it seems that VMware also does not see the license dongle, and the "workaround" is to physically re-connect the license dongle to the ESXi server or do a remove/add of the USB device in VM Settings on the Aspect Server.
I have verified that there are no power saving settings enabled on the usb device or usb controller in Windows device manager. On one of the systems firmware, software etc. on the host was updated to latest and greatest, but the issue still returned.
Anyone seen something similar?
