After installing WinUSB via libwdi for the FT232R and FT2232H parts, I am
able to run examples/eeprom on these devices. However Win32 no longer
provides the VCP interface, so that the final purpose of the programmed
devices, to display information via Hyterterminal or such, is not available.

Is there any time frame for the filter driver?
