The 1U SE/HMC chassis did have an internal USB attached Smart Reader. This was 
always present! You would have to take it apart to access this USB attached 
devices đŸ™‚

Subject: HMC and zombie USB device

As many of us know HMC reports all external devices connected via USB -
mice, keyboards, pendrives, etc.
That's good from security point of view.
However I noticed some HMC (2.15) report *non-existent* device. Yes, I
checked it thoroughly. Imagine pizza-box HMC machine and all the cables
and ports clearly visible. No place to hidden plug or USB hub. However
the HMC reports Gemalto SmartCard Reader.
SmartCard reader is typical equipment of TKE, but not HMC. And it is
*not connected* externally. And I strongly doubt it could be connected
internally - 1U chassis cannot contain SmartCard reader hidden inside.
Yes, I'm pretty sure the HMC reports that device - I restarted HMC and
observed all the messages. There is absolutely no way someone
plugged/unplugged it during the process.

Any clue?
