the port resets work on the laptop now. the bit we were waiting on (port-enable-changed) was being acknowledged by the bios’s smm ghost before we ever saw it, so we stopped waiting on the status bit and just read the port state, which can’t be acked away. also fixed before it bit us: two devices answering address 0 at once (enumeration is per-port now, and every device gets a real address before the next port wakes up). the next failure was prettier: every OUT transfer works, every IN transfer dies. the stick takes its orders but can’t talk back. that’s the signature of the qtd buffer list, the one place real ich silicon is strict where qemu is forgiving, so all dma buffers are page-aligned now and the error reports name whichever endpoint stalled. also everyone gotta apreciate the blahaj!
