None was born wise, BH is trying to be.
Is your dongle working with official image? BH is based on that one and is trying to do the best.
DISCLAIMER
THE BLACK HOLE IMAGE IS BASED ON THE OFFICIAL FIRMWARE PUBLISHED BY VU+ AND IN ACCORDANCE WITH THE LAW IT CONTAINS ONLY SYSTEM ADDITIONS & GRAPHIC CHANGES.
Yes, it works with official image. I bought my Solo2 2 months ago. First, upgraded from official image to Blackhole 1.7.9-3 latest available at that time. When the new version was released i.e. Blackhole 2.0, the dongle stopped working.
Both Vu+ Solo2 and the dongle I bought in Germany.
