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

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.

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