Keyboard and mouse behind that hub are therefore dead after boot. Kernel log on 7.0.0-34 (every boot): usb usb7-port1: attempt power cycle usb usb7-port1: unable to enumerate USB device On 7.0.0-31 (and 7.0.0-28/29/30) the same hub enumerates at ~2.9 s, with keyboard and mouse behind it. The same hub DOES enumerate on 7.0.0-34 when hot-plugged after boot, so the hardware is fine; only cold-boot enumeration fails. Statistics from journal: 19/19 boots OK on 7.0.0-28..31, 3/3 boots FAIL on 7.0.0-34. Booting 7.0.0-31 again fixes it (currently pinned as GRUB default as a workaround). The 7.0.0-32/-34 changelog contains no obvious USB/xHCI change, so the cause may be indirect (timing/PCI/power management). HARDWARE: Board: Gigabyte B650 EAGLE, BIOS F35 (2025-07-16) CPU: AMD Ryzen 9 9900X Controller: 11:00.0 USB controller [0c03]: AMD Raphael/Granite Ridge USB 2.0 xHCI [1022:15b8] (subsystem Gigabyte 1458:5007), behind 00:08.3 Internal GPP Bridge Hub: Genesys Logic 05e3:0608 USB2.0 Hub Devices behind hub: INSTANT USB Keyboard 30fa:2053, Microsoft Comfort Mouse 4500 045e:076c GPU: NVIDIA RTX 4090 (nvidia-dkms-595-open 595.91.07) VERSIONS: Good: 7.0.0-31-generic (7.0.0-31.31) Bad: 7.0.0-34-generic (7.0.0-34.34) ATTACHMENTS: dmesg-7.0.0-34-fail.txt, dmesg-7.0.0-31-ok.txt, lsusb-t.txt, lsusb-v-hub.txt, lspci-nnk.txt STEPS TO REPRODUCE: 1.
