Under "Bluetooth subsystem support" I removed support for "SCO links support", and then under "Bluetooth device drivers" I removed SCO (voice) support. What is still left: HCI USB driver HCI UART driver -UART (H4) protocol support -BCSP protocol support HCI BCM203x USB driver HCI BlueFRITZ! USB driver HCI VHCI (Virtual HCI device) driver I realize that some of these shouldnt be in there, but I don't think they are causing problems, either. Anyway, after I removed the items mentioned above, and after plugging in the bluetooth adapter, this is what I get: Oct 9 20:24:17 Obliterus usb 4-1: new full speed USB device using uhci_hcd and address 2 Oct 9 20:24:18 Obliterus usb 4-1: USB disconnect, address 2 Oct 9 20:24:18 Obliterus Bluetooth: HCI USB driver ver 2.8 Oct 9 20:24:18 Obliterus usbcore: registered new driver hci_usb So it looks like it immediately disconnects. It doesn't show up with lspci at all either. I havent tried using the hci_usb as a module and setting isoc=0 yet, but am I correct that removing the SCO stuff from the kernel took care of the problem, since I no longer get the same message? Thanks
