USB TRNG - Moonbase Otago - OneRNG

[Tom]

Howdy,
I've got one of these (a v3.0 to be exact) and I'm trying to get data out 
of it. I found some info on one of their mailing lists but it doesn't 
really get me anywhere:
http://lists.onerng.info/groups/onerng-talk/messages/topic/KFurGvvNZPq5dh7XQyX14/

If I attempt to open the device with tip, the device detaches.

dmesg output:
Mar 28 15:50:13 xyz kernel: umodem0 on uhub1
Mar 28 15:50:13 xyz kernel: umodem0: <Moonbase Otago 
httpwww.moonbaseotago.comrandom 00, class 2/0, rev 2.00/0.09, addr 3> on 
usbus0
Mar 28 15:50:13 xyz kernel: umodem0: data interface 1, has no CM over 
data, has break

Its been a while since I've debugged something like this so I'm hoping I'm 
missing something simple. I'm in the SFBA if someone wants to borrow this 
thing to figure it out.
