[Bluez-users] bcm2045 issue

[Jeffrey Bridge]

Hi,

I'm not sure if this is supposed to work yet or not, but I'm having
trouble getting a Dell Wireless 355 module (AKA BCM2045) working in an
e1705 under Gentoo. Here is the error message generated upon 'modprobe
hci_usb':

Bluetooth: HCI USB driver ver 2.9
usbcore: registered new interface driver hci_usb
hci_usb_intr_rx_submit: hci0 intr rx submit failed urb ffff81007a5c4ea8
err -28
hci_cmd_task: hci0 command tx timeout


If I then try to run 'hciconfig hci0 up', it says:

Can't init device hci0: Input/output error (5)

And the kernel also outputs another:

hci_usb_intr_rx_submit: hci0 intr rx submit failed urb ffff8100763848e8
err -28



Here's all the system info I know of which may be relevant.

$ uname -a

I saw some other people asking about this, but I was unable to find any
definite answers. Does anyone how to get this to work? Please let me know
if I need to supply more info about my configuration.

It still gets the same result with reset=1:

hci_cmd_task: hci0 command tx timeout
hci_usb_intr_rx_submit: hci0 intr rx submit failed urb ffff81004d45faa8
err -28
