Hi Brad,<br><br><div><span class="gmail_quote"></span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><br>&nbsp;but it seems that the broadcom was
<br>erroneously returning a 0 in an mtu field</blockquote><div><br>Thanks for the heads up. <br>
<br>
I tried the Broadcom patches didn't seem to work fo me<br>
<br>
I applied the patch from here
<a href="http://sourceforge.net/mailarchive/message.php?msg_id=14450798" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://sourceforge.net/mailarchive/message.php?msg_id=14450798</a> and here
<a href="http://sourceforge.net/mailarchive/message.php?msg_id=14772190" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://sourceforge.net/mailarchive/message.php?msg_id=14772190</a><br>
<br>
using both and either one at a time. I never got much joy.<br>
<br>
(p.s. is there a better way of recompiling than make modules;make modules_install?)<br>
<br>
The patch seems to correctly set the sco field:<br>
<br>
[root@mythtv keith]# grep hci_cc_info_param /var/log/messages | grep mtu<br>
Feb 11 16:21:24 localhost kernel: hci_cc_info_param: hci0 mtu: acl 377, sco 16 max_pkt: acl 10, sco 8<br>
<br>
But I still don't get any audio, similar to other complaints.<br>
<br>
>From hcidump, it looks like for some reason the driver decides not to send any data.<br>
<br>
The headset/dongle where a budget pack from maplin.<br>
Dongle: LM Technologies BTU01D<br>
Headset: LM Technologies BHS02C<br>
<br>
That'll teach me for not getting a known brand. Oh well.<br>
<br>
Attached is the info I can pull from various sources<br>
<br>
If anyone has any other ideas, I'm keen to hear them.<br>
<br>
Cheers,<br>
<br>
