Bluetooth with Ralink RT3290 on HP ProBook 4740s

[Xificurk]

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:

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.

I am interested to see if some resolution can come from this other than to replace the hardware, as I have a HP dm-1 with the rt3290 chipset.

The wireless device seems to work perfectly fine using the kernel-based rt2800pci driver, however bluetooth seems to be lacking.

In addition to the Ubuntu forum link above, I have also found this one which provides a link to some drivers to be compiled for both the wireless and bluetooth functionality of this chipset.

The problem, however, is that from what I've been able to garner from the limited sources of information on it, these drivers have a problem with newer versions of the kernel. They won't compile. And, unfortunately, this sort of programming is beyond me for now...

Anyone think they could have a look?
