Hello,
I've recently bought HP ProBook 4740s and I'm having trouble getting bluetooth working.
The piece of hardware in question is Ralink combo wifi+BT card:
| Code: | 04:00.0 Network controller [0280]: Ralink corp. RT3290 Wireless 802.11n 1T/1R PCIe [1814:3290]

Memory at d0610000 (32-bit, non-prefetchable) [size=64K]

04:00.1 Bluetooth [0d11]: Ralink corp. RT3290 Bluetooth [1814:3298]

Memory at d0600000 (32-bit, non-prefetchable) [size=64K]

I've successfully got the wifi part working with rt2800pc module and rt32900.bin firmware from linux-firmware package, but bluetooth is not working. I've tried enabling anything remotely related to BT with no luck... rfkill list shows only wifi card, so it's not a problem of BT being simply blocked.
I'm running latest stable amd64 with kernel 3.7.10.
Any suggestions how to get it working?
Google search revealed that users have similar problems on other distros as well, but I think there must be a solution to this, since HP sells laptops with this card with SLED (and HP support told me that presumably Arch Linux has it working as well). |

I'm an Arch user, but I thought I'd register here to share with you what I know.
I did some research on this last month when I got my new computer (an HP dm1-4341sa) with the same wireless/BT chip, and I could not get the Bluetooth working. My research at the time suggested that there was some patent-related reason that there is no supported linux driver.
In trying to find that page again I also found this page on the Ubuntu forums where someone claims to have found a Bluetooth driver which actually works for this chip.
What I myself did to 'solve' the problem was look up the service manual for my model on the HP website, locate the (small!) list of compatible (i.e. on their hardware whitelist) wifi chips, and swap out the Ralink for one of those with linux support.
Hopefully I've been able to give you something useful. Good luck.
