Terratec has granted us a permission to re-distribute the firmware:
http://www.linuxtv.org/downloads/firmware/#7
I'll be submitting the firmware to linux-firmware tree.
The enclosed patch should make it to work, once the firmware is downloaded
and copyed into /lib/firmware.
Please test.

Subject: [media] em28xx: Change firmware name for Terratec H5 DRX-K
Use a name convention for the firmware file that matches on the
current firmware namespacing. Also, add it to the firmware
download script.
