I just wanted to ask about the status of this issue.
Cheers

Hi,
Please try to subtract the offset from the initial '_map' call:
That didn't do it, because it still uses the base address with offset for the io mem connection. What did help was to use _base - _offset() in the constructor of Io_mem_connection. Now I could successfully boot genode with USB input devices and launch scout.
But that is of course a very dirty hack to get it running. The question is, why the creation of io_mem_connection fails, or if the memory map has some issues.
