Hi Herman,

  

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?
    

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.

Regards

Marcel
