ChronoVu LA8
The ChronoVu LA8 is a USB-based 8-channel logic analyzer with up to 100MHz sampling rate. It features a Xilinx CPLD for sampling, 8MB of built-in SDRAM to store the samples, and can trigger on low or high states of any combination of probes. After the 8MB sample buffer is full, the data is transferred to the host using an FTDI USB-to-serial chip.
See ChronoVu LA8/Info for more details (such as lsusb -vvv output) about the device.
