Hi, I am trying to make a buildroot system for the cubox-M we bought. I based my work on: [https://github.com/SolidRun/imx8mp\_build](https://github.com/SolidRun/imx8mp_build). I am trying to connect a touch screen to the Cubox-M. The information for my touch screen are: - Product: MTouch - Manufacturer: TSTP SerialNumber: CMTP\_1.0 idVendor: 0416 idProduct: c168 . I have seen that I had to add this in the linux defconfig: > **[Winbond Electronics MTouch](https://linux-hardware.org/?id=usb:0416-c168)** > > A database of all the hardware that works under linux I have tested it by connecting to my own laptop, it works correctly. However, when I connect it to my cubox-M, it connects then disconnect a bit later with the logs: [670.932490] usb 1-1: new full-speed USB device number 2 using xhci-hcd [671.121189] input: TSTP MTouch as /devices/platform/32f10100.usb/38100000.dwc3/xhci-hcd.0.auto/usb1/1-1/1-1:1.0/input/input2 [671.134296] imx-wm8904 sound-wm8904: failed to find codec platform device [672.996958] audit: type=1701 audit(1599913662.076:72): auid=4294967295 uid=0 gid=0 ses=4294967295 pid=801 comm=“o25-gui” exe=“/usr/bin/o25-gui” sig=6 res=1 [681.440442] xhci-hcd xhci-hcd.0.auto: xHCI host not responding to stop endpoint command.

it is possible this is due to the kernel usb autosuspend code. Can you please test by adding `usbcore.autosuspend=-1` to your kernel commandline? Thanks. ---

Hi, Thanks for the reply. I tested to change usb autosuspend in the bootargs as you adviced. I also tested by changing this in the linux defconfig. Nevertheless, none of this tests was successful. ---

Could you post the full output of `dmesg` so I can look at the full kernel boot and enumeration? ---

My kernel image is BR2\_LINUX\_KERNEL\_CUSTOM\_REPO\_VERSION=“rel\_imx\_5.4.70\_2.3.0” as it was done in here: [GitHub - SolidRun/imx8mp\_build: IMX8M Plus buildroot build script](https://github.com/SolidRun/imx8mp_build) ---
