b) More worryingly, the Emagic EMI 2|6 firmware appears to be under a "license" which prohibits ANY redistribution. Quoting from emi_26_62/license.txt (my emphasis):
"The firmware contained herein is Copyright (c) 1999-2002 Emagic as an unpublished work. This notice does not imply unrestricted or public access to this firmware which is a trade secret of Emagic, and which ***may not be reproduced, used, sold or transferred to any third party without Emagic's written consent.***"
The emi firmware files are copies of linux/drivers/usb/misc/emi26_fw.h and emi62_fw_*.h. emi26_fw.h contains three copies of this "license", but only the first one contains this paragraph which is missing in license.txt:
| Permission is hereby granted for the distribution of this firmware | image as part of a Linux or other Open Source operating system kernel | in text or binary form as required.
I've added this paragraph to license.txt.
Does the ALSA project have special authorisation ("written consent") to distribute this?
Well, I'd guess the alsa-firmware package is part of Linux.
Please note that the emi26 and emi62 drivers still use the in-kernel copies of their firmware images; the files in alsa-firmware are as yet unused.
Does anyone have a contact at Emagic (which seems to have been bought by Apple) to discuss relaxing the firmware conditions slightly?
Emagic helped writing the emi26 driver, but these devices were discontinued shortly after Apple bought Emagic. AFAIK nobody now at Apple knows, or cares.
