Partly. It works fine with my mouse, but my keyboard, that was happy before
now after some "roundtrips" gets unhappy and does no longer reconnect. (i
changed the idle timeout to 30 seconds to test).

I got stuff like that in hcidump:
2008-05-15 17:23:44.288599 > ACL data: handle 11 flags 0x02 dlen 12
L2CAP(s): Connect req: psm 19 scid 0x005c
2008-05-15 17:23:44.288640 < ACL data: handle 11 flags 0x02 dlen 16
L2CAP(s): Connect rsp: dcid 0x0000 scid 0x005c result 4 status 0
Connection refused - no resources available

And then my dongle spontaneously disconnected itself from the USB bus and
reconnected.

I have not seen this again since then, but maybe it is something to watch o=
ut for.
