Touchscreen on jetson nano-waveshare stop to working

Xorg.0.log (15.7 KB)

Is your touch function connected through a usb?

This is my screen

Ok, so it is usb interface.

Will the touch back to life if you plug the usb cable?
Will you see this device in “lsusb” command even when the touch is in no response state?

Which software release are you using?

I run lsusb before and after the state no response.I get:

lsusb
Bus 002 Device 002: ID 0bda:0411 Realtek Semiconductor Corp.
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 093a:2510 Pixart Imaging, Inc. Optical Mouse
Bus 001 Device 003: ID 0483:5750 STMicroelectronics
Bus 001 Device 002: ID 0bda:5411 Realtek Semiconductor Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Could you check if it is always same time period before the input device becomes dead?

Open a terminal, run xinput command and see what is the result.

Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ STMicroelectronics STM32 Custom Human interface id=6 [slave pointer (2)]
⎜ ↳ PixArt USB Optical Mouse id=7 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ gpio-keys id=8 [slave keyboard (3)]

can you use command

“xinput enable 6” and see if any new log coming from Xorg.0.log? Also, will the touch back to life with this command?

this is when touch run

when touch don’t work there isn’t the id 6…then i have an error:unable to find device 6

approximately 1 minute and 5 seconds,
approximately same time period

Will the touch go to dead status if you don’t put it in idle?

While writing a file (using the touchscreen) it suddenly doesn’t work anymore

Hi,

Could you dump dmesg log right after the error happens?

Boot up the device with touch connected. Use command dmesg > kernel_log.txt after the error happens and share the log with us.

Will the touch back to life if you use this method to toggle the usb hub?
