** Description changed:
PACKAGE: linux (Ubuntu)
DESCRIPTION:
After upgrading from linux-image 7.0.0-31-generic to 7.0.0-34-generic
(resolute, via
linux-generic-hwe), a USB 2.0 hub (Genesys Logic 05e3:0608) connected to the
single port of the
CPU-integrated USB 2.0 xHCI controller is no longer enumerated at boot.
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. Hub 05e3:0608 plugged into the port wired to the CPU USB2 xHCI
(1022:15b8)
2. Boot 7.0.0-34-generic -> hub not enumerated, "usb7-port1: unable to
enumerate USB device"
3. Boot 7.0.0-31-generic -> hub + keyboard + mouse enumerated normally
