Python can then be used to send USB commands in real time. Think of this as doing the same thing the Bus Pirate does for SPI and i2c, except that it’s doing it on the USB protocol itself.

That’s why [Jim Heaney] created the I2C-USB-Hub. The device takes your standard USB 2.0 hub circuit, and adds in a MT9700 P-MOSFET load switch for each port.

National Instruments has developed a new USB interface device – the USB-8451 – for use with inter-integrated circuit (I2C) and serial peripheral interface (SPI) communication devices. For use in ...

Gowin GoBridge is a family of bridging chips that convert a USB interface to different serial and parallel busses. “The GWU2X family enables conversion between USB and four peripheral interfaces: JTAG ...

Compliant with the USB 2.0 hi-speed standard, this is a feature-rich single chip bridging solution with I²C and multi-channel SPI interface capabilities.
