IIRC, the crash happens only if he has hcid and sdpd running. I haven't seen this crash on an OHCI host adapter, but I can't proof that this is an UHCI problem.

Yes, of course. Every help to track this problem is welcome. Please post bug reports or patches to the USB developer mailing list. > BTW: marcel & max, can i ask you what tools you use to debug your bluetooth > kernel code? printk? kgdb? kdb? I use the good old printk ;) Regards Marcel ------------------------------------------------------- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.
