None of the 2215 updates add a BT headset profile. (HID is Human Interface Device, which is a different profile.
This Brighthand thread indicates the reg hacks required to expose the headset profile on a 2215

Note that this works because the 2215 has the profile loaded, just turned off by default. This hack doesn't work on everything that doesn't show a headset profile. The BT headphones that HP sells come with a BT update that adds headphone and HID support, but that is different than headset.
