Bluetooth3.0: No HS Speed

Bluetooth3.0: No HS Speed

[Steffen Becker]

Hello,
When I send datafiles (.mp3, .wav or .avi ; size >10 MB) then it is 
transfered only with Bluetooth-speed (~2MBit/s), and not with 
"Highspeed". I have two Bluetooth 3.0+HS Dongles and also the 
integrated wlan-chip is recognized: "ifconfig displays a wlan-adapter; 
and I don't have any wlan-card or -dongle in my PC, so I think this 
displayed wlan-adapter is the one from the Bluetooth-dongle.

I have a Windows PC with two virtual machines in it: Two Ubuntu12.04 
systems. I inserted the two Bluetooth 3.0+HS dongles in my Windows PC 
and created an USB-filter for each dongle to one Ubuntu system. So as I 
said before, datatransfer via Bluetooth between these two virtual 
Ubuntu systems works fine and also the wlan-adapter is displayed under 
ifconfig - but I only have bluetooth-speed =(

What's the problem?

Regards,
Steffen

First you need High Speed support in the dongle. When you insert dongle
you should see 2 HCI devices: BREDR and HCI_AMP - which is High Speed
controller. Second you have to wait till we merge our patches upstream and
add High Speed support maybe later this year...
