About

I want to share the result of a long-standing obsession: a USB controller I built by hand. It does one thing, but that one thing matters—it gracefully takes back control of a storage device (its identity, every sector’s read/write permissions, and the data itself) from the host and returns it to the device’s owner. The most tangible outcome is that an ordinary USB flash drive or SD card can be sliced into multiple disks that appear completely separate to the host. On my prototype, I implemented four independent disks.
