I have a couple of the non-Gold versions. Plastic with a push button. They
have one sensor in the USB blob and a second sensor on a 3ft cable. There is
Linux code that lets you grab a reading when you want.
Temperature (internal) 76.21F 24.56C

Yes, it's HID. I don't know anything about that area. The Linux code is
big/ugly (my opinion) enough that I didn't just extract the few lines of code
to stuff into my code but called their run-from-the-shell package. It's open
source so it shouldn't be too hard to figure out how it works.

The blurb for the Gold version said LM75. I haven't taken the cover off a
non Gold version.
These are my opinions. I hate spam.
