I’ve got 3 CuBox-M Quad modules for evaluation, The first problem I’ve noticed is that attaching a USB device to the USB host ports on the CuBox will not power the USB devices. It is unclear to me if this is a problem with the batch of units I’ve received, or if I’m doing something wrong. What I’ve tried: I downloaded the pre-built image from [Here](https://images.solid-run.com/IMX8/imx8mp_yocto_gategarth-5.10.9-1.1.0?_ga=2.153133887.606664945.1634045155-1178325346.1634045155) and flashed it, then booted up, I can see the OpenEmbedded GUI served over HDMI, but connecting a mouse/keyboard to the USB host ports doesn’t work, the mouse isn’t even powered. Am I missing something fundamental or do I have faulty boards? ---

I believe those images need to be rebuilt with some additional patches. You can test with the Debian images that are available here [https://solid-run-images.sos-de-fra-1.exo.io/IMX8/Debian/](https://solid-run-images.sos-de-fra-1.exo.io/IMX8/Debian/) I will get the Yocto images updated ASAP and update this thread when the CI has built them. ---

Thanks for your response jnettlet, but the link you provided is broken ---

Isn’t the modern internet fun. Here is the generic link, [SolidRun Images](https://images.solid-run.com/IMX8/Debian) ---

That link works thanks! So I’ve zeroed my sdcard and dd transferred [Debian bullseye](https://solid-run-images.sos-de-fra-1.exo.io/IMX8/Debian/sr-imx8-debian-bullseye-20210706-cli-imx8mp-sdhc-cubox-pulse.img.xz). I’m assuming the image doesn’t come with a UI since there’s no HDMI signal, which is fine, but I still can’t get the mouse to power up. I also can’t check if it is actually detected as a USB HID device since there’s a password on the ssh root login which I do not know (where can I find this password?), and the serial console doesn’t work, but I’m assuming it has the same issue since the mouse isn’t powered To be more specific, I have this product: [IMX8m plus CuBox M](https://shop.solid-run.com/product/SRMP8QDW00D01GE008X00CE), and the power adapter that is suggested on the same purchase site. ---

Managed to get a serial console on one of the boards (previous board did not work), so I tried checking for a storage device from u-boot: after attaching a USB thumb driver, and interrupting the boot process, I see: ```auto Fastboot: Normal Normal Boot Hit any key to stop autoboot: 0 u-boot=> usb start starting USB... Bus usb@38100000: Register 2000140 NbrPorts 2 Starting the controller USB XHCI 1.10 Bus usb@38200000: Register 2000140 NbrPorts 2 Starting the controller USB XHCI 1.10 scanning bus usb@38100000 for devices... 1 USB Device(s) found scanning bus usb@38200000 for devices... 1 USB Device(s) found scanning usb for storage devices... 0 Storage Device(s) found ``` it cannot find the storage device, so I believe it’s a power issue, but maybe this is expected? Am I supposed to do something to the CuBox to get the USB host to function? ---

I will post an image for you to test. Sorry about the confusion I thought my patches had been merged into that image already. ---

Thank you jnettlet, but what would be helpful is knowing how to make the changes in your yocto layer (or extending it with a bb to add the changes in our own layer), which would make more sense for our workflow. in an email, someone from solidrun suggested the following to test: ```auto echo 7 > /sys/class/gpio/export echo out > /sys/class/gpio/gpio7/direction echo 1 > /sys/class/gpio/gpio7/value ``` This works, so I"m trying to figure out where to make this change to be the default behaviour of the platform
