There's a best-effort driver to acquire raw samples from any FTDI chip supporting bitbanging. It doesn't guarantee overrun-free operation so it may lose samples, yet moving the device to a separate USB host or lowering the sample rate helps.
Hardware
FT232RL and FT2232H are known to work, and adding an unsupported chip should be easy. Boards with the former are available on ebay for $3, but it doesn't support USB 2.0 hence sample rates will be lower.
