Persistent USB Issues on Pop!_OS 22.04 with Acer Aspire 3 - Logs Included

_OS community, I’m experiencing persistent USB issues on my Acer Aspire 3 running Pop!_OS 22.04, and I’d appreciate some guidance. The problem involves frequent USB controller failures and device disconnections, which don’t occur when I use the same peripherals on Windows 11. I’ve tried multiple troubleshooting steps, including updating the kernel, disabling the touchpad, and using a new mouse with a lower polling rate, but the issue persists. **Background** Hardware: Acer Aspire 3 notebook. OS: Pop!_OS 22.04 (based on Ubuntu 22.04). Peripherals: Previously used a Corsair Harpoon RGB PRO (1000Hz polling) and now a YSPRINGTECH USB OPTICAL MOUSE (lower polling rate), plus an internal ELAN050A touchpad. Observation: On Windows 11 (dual-boot), there are no USB problems with the same setup, suggesting a Linux-specific driver or configuration issue. **Symptoms** USB devices disconnect or require resets. The xHCI controller reports errors, especially during resume from suspend. Additional issues with power management, Acer WMI, and SATA links are present, which might be related. **Troubleshooting Attempted** Updated the kernel to the latest HWE version (e.g., 5.15.0-107). Disabled the touchpad (ID 17) using xinput disable 17 to rule out its interference. Switched to a mouse with a lower polling rate (10000us 4 times, consider switching to WQ_UNBOUND [Jun 28 12:35:03] workqueue: power_supply_changed_work hogged CPU for >10000us 5 times, consider switching to WQ_UNBOUND [Jun 29 20:39:47] workqueue: power_supply_changed_work hogged CPU for >10000us 4 times, consider switching to WQ_UNBOUND [Jun 29 20:39:56] workqueue: power_supply_changed_work hogged CPU for >10000us 5 times, consider switching to WQ_UNBOUND [Jun 29 20:40:04] workqueue: power_supply_changed_work hogged CPU for >10000us 7 times, consider switching to WQ_UNBOUND [Jun 29 20:40:54] workqueue: power_supply_changed_work hogged CPU for >10000us 11 times, consider switching to WQ_UNBOUND [Jun 28 12:28:18] acer_wmi: Unknown function number - 8 - 0 [Jun 28 12:38:51] acer_wmi: Unknown function number - 8 - 0 [Jun 28 12:38:56] acer_wmi: Unknown function number - 8 - 1 [Jun 29 20:32:37] acer_wmi: Unknown function number - 8 - 0 [Jun 29 20:39:32] acer_wmi: Unknown function number - 8 - 0 [Jun 29 20:39:34] acer_wmi: Unknown function number - 8 - 1 [Jun 29 20:41:03] acer_wmi: Unknown function number - 8 - 0 [Jun 29 20:41:08] acer_wmi: Unknown function number - 8 - 1 [Jun 28 12:38:57] ata1: SATA link down (SStatus 0 SControl 300) [Jun 29 20:39:09] ata1: SATA link down (SStatus 0 SControl 300) [Jun 29 20:41:09] ata1: SATA link down (SStatus 0 SControl 300) [2247.818144] ACPI BIOS Error [13.652880] TSC found unstable ``` I’d love to get advice from the community on how to stabilize the USB subsystem. Could this be a driver issue, a BIOS incompatibility, or a power management problem? Any suggestions on further diagnostics or fixes would be greatly appreciated. I’m hesitant to update the BIOS without confirmation, given the risks. Thanks in advance for your support!
