USB sniffer

Would it be possible to turn V-USB in a USB sniffer? Every time a USB packet is received, it could be dumped using e.g. SPI or a fast UART. Suppose the packets are coming not too fast, then it would be nice to turn the V-USB in a sniffer by not using the resistors (high impedance), and disabling the Tx functions.

Has this be done before? It would be great to have a ' hardware' USB sniffer for reversing USB (1.1, slow) devices.
