    I got another one of these adapters, and when I plug the new one in I get:

    usb 4-1: new full speed USB device using uhci_hcd and address 2
    Bluetooth: HCI USB driver ver 2.8
    usbcore: registered new driver hci_usb
    hcid[30219]: Bluetooth HCI daemon
    hcid[30219]: HCI dev 0 up
    hcid[30219]: Starting security manager 0

    Then I remove that one and plug in the original and get the old problem:

    usb 4-1: new full speed USB device using uhci_hcd and address 3
    hcid[30219]: HCI dev 0 registered
    usb 4-1: USB disconnect, address 3
    hcid[1984]: Can't init device hci0: No such device (19 )
    hcid[30219]: HCI dev 0 unregistered

    So the old one I was using seems to be a bad device, I just want to ask
    if there are any other possibilities, other than bad hardware, before I
    get rid of it.

    Thanks
