I am also highly sceptical about the claims.

It only support SPP and USB 1.1.

And it is strange that they mention the 2nd option. When the
host USB port is available, why bother with this device?

And a add-on PCI USB adapter is cheaper. So I think this
does not make much sense for a PC.

I then thought maybe this is useful for some embedded
device (like an embedded PC-104 PC with DOS), but
according to this page, it is not that easy either.
