thanks , I got it.I Should have known better before. I hoped hints for a balancer would still make s.th. still possible. But, …( never mind … )
I thought about taking power from the internal USB connector (?)
But yes, you’re together with Dirk on the right side when FT201 with internal USB host is the better (and cheaper) approach. But not for point of view from the software. Maybe I was not too clear about only starting with FTDI chips that has complete android driver software ready to use. Maybe you or Dirk only missed the point of my approach of FTDI2 VNC2 : this chip doesnot need the usb slave access but also needs power given from the internal usb host.
My qemu emulator actually has usb support and even your example already have had it. ( you left me a bit puzzled) . Recommending to use my productive FP2 as the testing and qualifying device extended a bit the puzzles in my head. You may have seen I am not that expert as you definetly are. Using qemu emulator for staging to me still looks mandatory. Just let me give it a try.
