Hi guys,
I hope one of you can help me... I am trying to use a USB 2.0 bluetooth
dongle (Belkin F8T012) through a USB 2.0 hub. The problem I have is that
whenever I insert the BT dongle the kernel reports the following error:
hci_usb_intr_rx_submit: hci- intr rx submit failed urb df265514 err -28
I have seen a conversation in which Marcel participated on the linux
kernel mailing lists which referred to a similar problem, but the
discussion was never really finished so no solution was given (see
http://lkml.org/lkml/2004/8/20/62). The problem seems to appear only
when using the ehci_hcd USB module. Because when I use the uhci_hcd
module (by rmmod ehci_hcd) it works. Does anyone have any idea what the
source of this problem is and how I might be able to solve it?
Regards,
Herman Meerlo

You are absolutely right off course. And upgrading the kernel did the
trick. Sorry for bothering you with this.

and again this seems to be an USB issue and not a Bluetooth issue. Take
it up with the USB guys and make sure you run the latest 2.6 kernel.
