I am trying to add usb floppy support for the esp32 host and this site is helping me a lot.
The current esp32 mass storage driver supports only bulk only transfer scsi, but usb floppies (those with the uf001f chip) use CBI(control/bulk/interrupt) and also UFI has a bit different command set: https://www.usb.org/sites/default/files/usbmass-ufi10.pdf https://www.usb.org/sites/default/files/usbmass-ufi10.pdf
By using this site, a cheap logic analyzer and usbpcap for windows, I am trying to go around reading all the usb docs :)
