Otherwise simply swap the mini-PCI card for an Intel one. This is slightly OT but I hope it might be of interest to some: I have already tried to compile the bcm43xx driver in OpenWRT kamikaze. Master mode will only work with the devicescape-branch of bcm43xx. Some OpenWRT co-users patched the Kamikaze kernel up to the latest code from the wireless-dev git repository. Unfortunately there was no joy there. Master mode does not yet run correctly, although the outlook is pretty good, as patches integrating bcm43xx and Hostap where sent to the bcm43xx devs and will hopefully get integrated soon. Unfortunately for me, I need WDS and this has not yet been coded. And Kamikaze kernel 2.6 USB is broken at the moment, so I couldn't test bluetooth operation on the 2.6 :( I'll look into swapping the mini-PCI card, thanks for the pointer. That might become a great alternative once the USB problems get sorted out. >> >> I have applied the changes in the 2.4.32 patch by Marcel, but I think >> they only refer to module unloading.

Will that suffice, or should I comment out the ISOC stuff in hci_usb.c? I don't think I'll manage a re-write of hci_usb :/ Waiting for solid 2.6 usb and bcm43xx support will definitely be faster than that ;) Regards and thanks, Kevin _______________________________________________ Bluez-users mailing list Bluez-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bluez-users
