Thank you Hans! > Hi Hans, For how many days I've been doing the automated printing the issue never occurred with DWC OTG debug level 17 but still for sure the issue is observed when debug is bypassed or disabled . That's why it's quite a challenge for me to capture. Not sure why this debug level 17 issue never appeared. Any ideas? Meanwhile, I've tried enabling 'sysctl hw.usb.ugen.debug=17' and this is what I've got. Not sure if this is helpful to you for any clue. When exactly the printing issue occurred this is what happened as found in the logs -> ugen_write_clear_stall_callback: f=0xffffa00016208d80: stall cleared. Below is the complete /var/log/messages (appeared twice) and the c-file-to-printer is my little printing program invoked.
