[Bug 460743] [NEW] 0a12:0001 Cambridge Silicon Radio Bluetooth Dongles do not work

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

I tried to connect an usb bluetooth dongle of this type on Ubuntu Karmic on a 64 bit system:
Bus 006 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

This device doesn't work, I always get from the kernel this error:
command tx timeout

I tried this on 2 (different) x64 systems, with the stock kernel (2.6.31-14-generic) and the new 2.6.32-rc5 kernel. Both show the same behaviour.
I also tried this with the stock bluez/libbluetooth etc and with the newest version from the Blueman PPA repository, also all with the same result.

When I tried the dongles (I have two of them) on a 32 bit system,
everything worked perfectly. (Also Karmic)

So I expect there is a bug somewhere in the 64 bit version.

I looked throughout the whole google searchable part of the internet to
find more information. All people with a such-like problems had
different causes apparently then mine, because none of the plentyful of
'tricks' didn't work.
