  "message": "usbh: add enumeration control transfer timeout\n\nA device that ACKs SETUP but never completes the following stage (e.g. NAKs\nthe EP0 IN data stage forever) froze the control state machine: enumeration\nnever finishes and hub interrupt polling never resumes, so one dead device\nblocks all further enumeration on the bus. Observed with a degraded USB disk\nbehind a hub on a rp2040 PIO-USB host: wire capture shows SETUP ACKed then\nan endless IN/NAK storm with no completion event.\n\nArm a watchdog (CFG_TUH_ENUM_TIMEOUT_MS, default 5s to match Linux\u0027s\nUSB_CTRL_GET_TIMEOUT, 0 disables) on enumeration-owned control transfers\nusing the existing call_after slot, which already wakes a blocked host task.\nOn expiry abort the transfer at hcd level and complete it as FAILED so the\nnormal enumeration failure path frees dev0 and resumes hub polling.\nNon-enumeration control transfers keep their current behavior.\n",
