Hi,
For some time I have been using a Sitecom Bluetooth USB Adapter
(Art.code CN-500V2) to send files to or save contacts from my mobile
(Nokia 2700c). lsusb reports it as Broadcom Corp. BCM2035 Bluetooth
dongle (ID 0a5c:200a). This worked fine on a Debian Squeeze (bluez 4.66)
and Ubuntu 10.04 (bluez 4.60). However using more recent systems on my
main machine (Debian wheezy & Arch Linux (both bluez 4.99), Fedora FC16,
Ubuntu 11.10) I did not get it to work for a long time.
It took me some time to find a reason to this. From a fresh install of
Debian squeeze I built multiple versions of bluez from source and found
that the problem is between commits 9d7109c and bca43a4 (version
4.84..4.85; 5b1a2a3 breaks it completely for me).
Setting event[2] |= 0x04 in set_event_mask in plugins/hcipos.c fixes the
problem for me. Sending files or retrieving contacts etc. from the phone
works without problems. But having no deep knowledge of the
communication between hardware and the kernel I don't know if this is
really a fix for the problem or just the symptom.
The testing was done with l2ping. In my setting the working version gets
50 responses until I get a "Connection reset by peer" message. The
non-working version gives me 10 respones (the last with a longer time),
4 messages "no response from ..." and after that a "Recv failed:
Connection reset by peer".
Here is some more data of the stick:

Please let me know if I can provide some more information.
Best regards,
Holger
