I have a Dell G15 5511 with an RTX 3050 and 11th-gen i7, and my touchpad keeps intermittently cutting out. In Device Manager, the failed device is I2C HID Device under Intel(R) Serial IO I2C Host Controller - 43E9, and it gives Code 10: “A request for the HID descriptor failed.” The I2C HID device uses the generic Microsoft hidi2c.inf driver, and the Intel Serial IO controller shows Intel driver version 30.100.2104.1. The Events tab shows the device being deleted/reinstalled, then “Device settings not migrated,” “Device configured (hidi2c.inf),” and “Device not started (hidi2c).”
I’ve updated the BIOS, installed the Dell chipset driver and Intel Serial IO driver, disabled power-saving options where available, tried a power reset, and disabled automatic driver replacement in Windows. Reinstalling or repairing the Intel Serial IO driver brings the touchpad back, sometimes even before restarting, but the issue eventually returns and the touchpad still cuts out from time to time. I’m trying to figure out if this is a known Dell G15 5511 Serial IO/I2C driver issue, a sleep/wake power-state bug, or a hardware problem like a loose touchpad ribbon cable or failing touchpad/palmrest assembly.

Hi,
Please do the following: if possible, access Device Manager > go to the L2C driver > Properties > Details > Hardware ID, and copy and paste it here.
Then, go to the USB controllers section, take a screenshot, and post it here.
It is quite likely a hardware issue.
Thanks.
I'm assuming you mean I2C HID Device. I went to Device Manager > I2C HID Device > Properties > Details > Hardware IDs and captured the screenshot below. I also attached the image of all my USB controllers.
Hi,
I’ve verified that the ID is correct, so this could be a hardware issue.
You can try installing the following drivers for Windows 10:
https://www.dell.com/support/product-details/en-us/product/g-series-15-5511-laptop/drivers
Intel Management Engine Interface Driver
Intel Chipset Device Software
Intel Serial IO Driver
Intel Dynamic Tuning Driver
AUO Panel Firmware Update Utility
Intel HID Event Filter Driver
Open the Command Prompt (adm) and run these commands: sfc /scannow and dism /online /cleanup-image /restorehealth. Wait for the process to complete and then restart your computer.
After that, test the system while connected to the charger to see if the problem occurs; if it doesn't, test it without the charger connected.
While this is not a Microsoft website, it is the official site of [G15 5511/ DELL].
Thanks.
