[Bluez-devel] hci_usb bug on 2.6 kernels?

Hi,

When I recently migrated to a 2.6 kernel, my TDK USB bluetooth adapter
stopped working. I could load all the modules fine, but as soon as I
start hcid I got the following error:

Aug 12 10:23:33 mulligans hci_usb_intr_rx_submit: hci0 intr rx submit
failed urb f744f5ec err -28

I've tried a few of the latest kernels, mainly 2.6.7 and the 2.6.8-rc
series and the problem remained.

Yesterday though, I switched my TDK from the USB2 controller to a USB1.1
~ controller and it worked.

I am using gentoo. Appended is the output from lspci:

00:1d.0 USB Controller: Intel Corp. 82801EB USB (rev 02) (prog-if 00 [UHCI])
00:1d.1 USB Controller: Intel Corp. 82801EB USB (rev 02) (prog-if 00 [UHCI])
00:1d.2 USB Controller: Intel Corp. 82801EB USB (rev 02) (prog-if 00 [UHCI])
00:1d.3 USB Controller: Intel Corp. 82801EB USB (rev 02) (prog-if 00 [UHCI])
00:1d.7 USB Controller: Intel Corp. 82801EB USB2 (rev 02) (prog-if 20
[EHCI])

this is weird, because error code 28 means ENOSPC (No space left on
device) and this is because of a bandwidth problem. May you wanna try to
disable CONFIG_USB_BANDWIDTH and see if it works then. Please report
this problem to the USB mailing list (no cross post), because I can't
really help here.

Regards

Marcel
