How to tell bluetooth version via lsusb or other means?

Does anyone know how to tell the
bluetooth version from lusb or some other way?

It's a USB dongle:

I found a few suggestions by googling for detect bluetooth version on linux, but haven't tried them. I doubt that lsusb is the right tool; it knows about USB, but not Bluetooth. It looks like you need hcitool.

Unfortunately hcitool doesn't see it. hciconfig does, but I've no idea what
the info means. I posted in another thread about it not working. This is the
hciconfig output anyway:

Code:
hci0:   Type: Primary  Bus: USB
BD Address: 00:1A:7D:DA:71:11  ACL MTU: 679:9  SCO MTU: 48:16
DOWN
RX bytes:574 acl:0 sco:0 events:30 errors:0
TX bytes:368 acl:0 sco:0 commands:30 errors:0
Features: 0xff 0xff 0xcd 0xfa 0xdb 0xbf 0x7b 0x87
Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3
Link policy: RSWITCH HOLD SNIFF PARK
Link mode: SLAVE ACCEPT
If anyone can decypher it, it would be handy.

I used -a but this dongle isn't working and doesn't
give any other info out than I posted above.

It was advertised as V 5.0, but I
see the same product and vendor IDs used for a v 2.0 dongle, which should work
OOTB according to 3 posts in the HCL and info I've found while trying to get it
to work.

I would think it strange that a company would update and keep the
same IDs, so I'm suspicious to say the least.

I've just tested it on a friend's Windows laptop and it does at least work after the software is installed.

I think I'll just have to put this one down as not for nix.
