Hello,
This patch adds support for the MCP2210 USB to SPI bridge as a programmer. Since the MCP2210 is an HID device I have a working version using both libusb and hidraw + udev for finding the device. I have already made a github pull request with more details: https://github.com/flashrom/flashrom/pull/68. But I am posting it here as well.
