USB_HID #974

Open kalyanikasam opened 3 months ago

kalyanikasam commented 3 months ago

Hello Joshua, I have noticed that USB_HID is built as a module in your configuration Ubuntu22.04 CONFIG_USB_HID=y, how can i change the parameter to 'm', as i am connecting a USB touch screen to Rock5B and was unable to get the touch functionality working until i manually map input to corresponding output which will happen only after user login. I have tried connecting the same display with radxa image, and the touch is working fine. I have gone compared the config files in both OS's and i have noticed that CONFIG_USB_HID=m in radxa image. Is this the issue. Please guide

Could you provide an example of how USB_HID is used as a module?

From my understanding all the radxa touch screens and displays now work perfectly.

This display is not from radxa it is a 7inch touch screen from waveshare which uses HDMI for display out and USB for touch interface https://www.waveshare.com/wiki/7inch_HDMI_LCD_(C). I have compared the configuration file from Ubuntun22.04 in /boot/config-5.10.0-1007-rockchip which says CONFIG_HID_MULTITOUCH=m and in config file in radxa image /boot/config-6.1.43-14-rk2312 CONFIG_HID_MULTITOUCH=y , Is this why my touch is not working until i manually map HDMI out to USB input using map-to-output
