The
Bluetooth adapter comes in a plastic wrapped case, the ones
you have to cut apart to be able to open them.

In
terms of contents, there’s not much: the Bluetooth adapter,
the quick start manual and the installation CD itself.
Here’s
a closer view of the adapter itself.

The
adapter is based on the Broadcom BCM2035 single chip solution.
On
their website you can find extensive information on the
workings of their chip solution. This
is some of what I could find:
This
shows a block diagram on the inner workings of the chip
and the next picture is the diagram of the chip used in
a PC solution.
“The
Broadcom BCM2035 is a monolithic single-chip, standalone
baseband processor with an integrated 2.4-GHz transceiver
for Bluetooth 1.1 and 1.2 applications. It eliminates the
need for external flash memories and active components by
integrating critical components into the device, thus minimizing
the footprint and system cost of implementing a Bluetooth
system.
The BCM2035 is the optimal solution for any voice and/or
data applications that requires the Bluetooth SIG standard
Host Controller Interface (HCI) via either USB or UART and
PCM audio interfaces. The BCM2035 is based on the production
and UnPlugFest proven architecture of the BCM2033 Bluetooth
baseband core (BBC), peripheral transport unit (PTU), and
microprocessor unit (µPU). The µPU stores the lower level
protocol stack in read-only memory (ROM) plus patch random
access memory (RAM) to provide the maximum flexibility.”
