Dangerous Prototypes Buspirate
The Dangerous Prototypes Buspirate supports a logic analyzer mode and can thus be used for sample captures, however only at low speeds. To quote from the announcement: The Bus Pirate can’t store a lot of samples, it can’t feed live samples very fast, and speeds are in the kHz range.
See Dangerous Prototypes Buspirate/Info for more details (such as lsusb -v output) about the device.

The buspirate (in logic analyzer mode) uses a simplified version of the "extended SUMP" protocol.
