LinkRegenerating every affected segmentOnce the bleeding had stopped, we still needed to deal with the segments that were already corrupted and actively being served to viewers. After much deliberation and with admittedly fairly limited options, we landed on a (coarse) approach: mark every rendition segment generated during the incident window as needing regeneration.

Understanding this requires a minimal understanding of how the USB device framework works. An excellent overview can be found here. In short, when talking to a USB device, data needs to be sent to or received from specific endpoints. A device can have multiple endpoints of different types and directions. Each endpoint is identified by an address, which can be found in the USB descriptors. The NXT uses two "bulk" endpoints, one in each direction, and their addresses are 0x01 and 0x82.
