CY7C68013A-56 EZ-USB FX2LP USB2.0 Develope Board Module Logic Analyzer EEPROM WC CY7C68013A-56 chip: low-power version of the enhanced 51-core, 16KB program data areas, clocked at 48Mhz, 480Mbps high-speed transmission protocol standards, in line with USB2.0 specification, backward compatible with USB1.1. May 06, 2013 I got one of those and it works with the included (very old and simple) version of Saleae Logic. Haven't used it much though, just verified that it works.
Cypress’s EZ-USB® FX2LP™ (CY7C68013A/14/15/16A) is a low power, highly integrated USB 2.0 microcontroller.

This chip is a General Programmable Interface (GPIF™) that is supposed to ease the development of USB devices such as keyboards, mouses (mice!), flash drives, etc.
The board that I ordered is a development board from AliExpress for $4.60 and I was really impressed with its quality.

There are 2 variants, one with one jumper & another with 2 jumpers. Both comes with a on/off switch and a RESET push button.
The board also has an EEPROM (ATMEL 24C128 on my board) which is used to hold the VID/PID/DID of the device - this is for the host to identify the device to determine the correct driver.
My board was of the 2 jumper model & I think both are the same.
J1 is to connect/disconnect 2 LEDs from Vcc - these LEDs are connected to D0 & D1
J2 controls the high address bit of the EEPROM making it appear at I2C address 0xA0 or 0xA2 depending on the jumper.
The FX2LP is designed with a unique feature that allows the firmware to be loaded to the chip RAM either from the host or from the EEPROM.
Here we will be discussing a very interesting firmware that converts this $4.60 board into a logic analyzer!
