Assessment

Difficulty: 4/5
Estimated time: 3-5 days
Newbie friendliness: 35/100

Issue type: Bug
Clarity: Needs clarification
Activity status: Quiet
Tech stack: linux, raspberry-pi
Domain: embedded-iot, operating-systems

Research direction

Start by reproducing the warning on the Raspberry Pi 3 Model B+ setup described, using the USB mass-storage device and PL2303 adapter and reviewing the supplied kernel logs. Trace the warning entry point named in dwc_otg_hcd_urb_dequeue and compare behavior with the reported kernel version. Done is not defined by the issue; clarify the expected USB behavior and a reproducible resolution before implementation.

Description

Hello.
Using a Raspberry Pi 3 Model B+ with latest Raspberry Pi OS (64-bit):

Linux rpi3 6.1.19-v8+ #1637 SMP PREEMPT Tue Mar 14 11:11:47 GMT 2023 aarch64 GNU/Linux

root@rpi3:~# cat /etc/debian_version
11.6

On one USB port I have a USB to RS485 adapter (using PL2303 chip):

On this RS485 interface /dev/ttyUSB0 I poll every 2 seconds a SDM120 Smart Meter (Modbus) with this software.
All works well except I have lots of WARN::dwc_otg_hcd_urb_dequeue:639: Timed out waiting for FSM NP transfer to complete on in /var/log/messages.

See here an extract:
