They have a lot of controllers. Have you already studied the older 8051 based and RISC ones, and looking for more research? you can find many firmwares on the usual flashboot / usbdev sites and throw them in IDA, but unless you have a more specific purpose or focus, I think you will not get much help. you might want to study the Phison work done a few years ago (badUSB IIRC) and see the general principals of reversing some usb controllers.
curious what your goal is on the research
