zephyr usbhs Sleep and wake up functions are not supported

hskating — Fri, 14 Feb 2025 03:33:35 GMT

I tested this example while debugging LPC55s28: samples/subsys/usb/hid-mouse CONFIG_USB_DEVICE_REMOTE_WAKEUP=y was set in samples/subsys/usb/hid-mouse/prj.conf, but after compiling the project: int usb_dc_wakeup_request(void) is not supported in drivers/usb/device/usb_dc_mcux.c; Please tell me how to solve this. I also used MCUXpressoIDE to generate a copy of lpcxpresso55s28_dev_suspend_resume_hid_mouse_bm\source\mouse.c, However, it is not possible to add examples to drivers/usb/device/usb_dc_mcux.c in zephyr. I think this also needs to support low power control. Is there a successful example in zephyr? Thank you very much.

Hi @hskating

Sorry, we currently do not support USB low power control on LPC55s28 Zephyr.

Will nxp mcu with usb support zephyr with low power consumption in the future?
