After the configuration descriptor's first 9 bytes the event loop asked for min(wTotalLength, 128) whatever it was. A wTotalLength of 9 or less was then asked for again as "short" -- for ever, that slot never leaving enumeration (#170); 0 also issued a zero-length data stage. A set longer than the 128-byte buffer was cut without a word, its later interfaces never seen (#171). The decision is usb_config_request_length() (moved out of the event loop, then fixed): 9 or less is 0 -- "xhci: a configuration of N bytes has no interface -- not used", and nothing more is asked; longer than the buffer is cut and said -- "xhci: config of N bytes cut to 128 -- rest unseen" (at most 53 characters). The buffer stays 128 bytes; its size is #171's to rule. kernel/tests/test_usb_config.c, seen to fail first against the decision as it was (10 failures: wTotalLength 1 to 9 asked for again, the cut unsaid), now 20 checks, 0 failures. Both runs in logs/20261112-180140/kernel-tests/. Built for amd64, aarch64 and riscv64; the boots come with the protocol. #171's other box, a composite device on the SER5, is Captain Bob's.
