Having Windoze doesn't always mean that it will update critical firmware components (it doesn't, and I barely use Windows). I just installed Ubuntu 13.10 on a usb drive along with the respective drivers (rt3290sta for wifi and rtbt for bt) and almost everything works as expected. However I noticed some things that as far I remember didn't happen in 12.04-13.04:

- When trying to send/receive a file, the transfer dialog returns an error (it doesn't even connect to the device).
- BT FTP browsing works, but nautilus gives an error (it was something like 'backend doesn't support this') when trying to download/upload a file to the bt client, which, in this case, was my phone. It's not my phone's fault, though.
- Oddly, applications can download data if you open anything. For example, if you open a picture, the image viewer will download and display it.
- The connection doesn't drop when using the PC as bluetooth speaker.
This suggests me that something is wrong in Ubuntu's bluetooth stack.

I've been following this since a while ago and I remember that back when Ubuntu 14.04 was out I tried:
- downgrading the kernel
- downgrading everything bluez-related
Nothing worked. I'm now thinking about downloading older Ubuntu versions on which the driver worked ok and then try upgrading bluez/kernel to see what happens.
Count me in if you want a tester.
