Maybe this depends on the USB host controller chip. I got reports that
some ALI chips misbehave when it comes to ISOC transfers. If you have
access to MacOS X you can unpack the firmware update from Apple and use
GenericCSR.dfu and btdfu-0.3 to update your D-Link dongle to HCI 18.1
and HID proxy. Don't try this if it is a revision B4 dongle.

You should also check that the SCO support for the hci_usb driver was
compiled in.
