Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

Transaction flow:

BULK[00081] <<< REPLY PACKET #1 64 bytes (PREVIOUS TRANSACTION REPLY)

General reply packet(s) are always used if not own reply defined.

|       | Just same reply packet as returned during previous transaction.
|       | Needed only if reply is missed in previous transaction.
