[Luca Santarelli]

From: Luca Santarelli <hrk <t> users.sourceforge.net>

As reported at:

and in reference of similar patches such as:
http://thread.gmane.org/gmane.linux.bluez.devel/15067

This patch changes the blacklist entry for the ISSC bluetooth USB
dongle fixing the issue of the repeatedly appearing message

  hci_scodata_packet: hci0 SCO packet for unknown connection handle 92

in the kernel logs.

This is my first kernel patch ever, I read the docs, but please notify
me if I made any mistake. Thank you all for your work, I'm happy to have
been able to contribute to this!

The patch has been run against 2.6.27.7 and has been tested on three x86
machines, showing no issues. In my own tests, the dongle has been then
used to connect to devices and everything worked fine.
