: There is a community-driven ASIO driver project for the BCA2000 on GitHub that uses the LibUsbK library to bypass old Windows driver signatures. This is highly experimental and for advanced users only.
The original BCA2000Ctrl.exe will not run on Windows 10 x64. You need an exclusive wrapper.
Even if you use USB, the BCA2000 needs the old FireWire stack.
Turn on the BCA2000. It will appear in as an "Unknown Device".
