Public bug reported:
== Summary ==
After kernel upgrade from 6.17.0-29-generic to 6.17.0-35-generic on June 1,
2025,
a GenesysLogic USB hub chain began repeatedly disconnecting and reconnecting.
The issue is fully resolved by adding usbcore.autosuspend=-1 as a kernel
parameter.
== Hardware ==
Machine: Beelink SER5 MAX Mini PC
CPU: AMD Ryzen 7 7735HS
RAM: 24GB LPDDR5
OS: Ubuntu (Noble), kernel 6.17.0-35-generic
BIOS: ASE32001
== Affected Devices ==
GenesysLogic USB2.1 Hub - idVendor=05e3, idProduct=0610
GenesysLogic USB3.1 Hub - idVendor=05e3, idProduct=0626
(3-tier hub chain on xhci buses 6/7, PCI 0000:05:00.3)
== Symptom ==
The entire hub tree (6-1, 6-1.4, 6-1.4.4 and USB3 counterparts on bus 7)
disconnects as a unit and reconnects repeatedly. Samsung uSD Card Reader
connected through the hub also drops. Mouse and keyboard on direct ports
are unaffected.
== Kernel version boundary ==
Working: 6.17.0-29-generic
Broken: 6.17.0-35-generic
Upgrade date confirmed via dpkg log: June 1, 2025
== What was ruled out ==
- TLP: not installed
- power-profiles-daemon: last updated July 24, 2024 — not a factor
- No over-current or reset errors in dmesg
- xhci_pci is built-in (modprobe reload not possible)
== Workaround ==
Adding usbcore.autosuspend=-1 to GRUB_CMDLINE_LINUX_DEFAULT
completely resolves the disconnects.
== Relevant dmesg pattern ==
Repeated sequences of:
usb 7-1: USB disconnect, device number X
usb 7-1.4: USB disconnect, device number X
usb 7-1.4.4: USB disconnect, device number X
usb 6-1: USB disconnect, device number X
usb 6-1.4: USB disconnect, device number X
usb 6-1.4.4: USB disconnect, device number X
followed by full re-enumeration of the hub chain.
