Hi,

I have nearly each day an discconnect of my CP2102 USB to UART Bridge Controller

In journalctl appears:

Dez 27 21:38:35 vcontrold kernel: cp210x ttyUSB0: usb_serial_generic_read_bulk_callback - urb stopped: -32
Dez 27 21:38:35 vcontrold kernel: cp210x ttyUSB1: usb_serial_generic_read_bulk_callback - urb stopped: -32

My CP2102 USB to UART Bridge Controller:

Bus 001 Device 004: ID 10c4:ea60 Silicon Labs CP210x UART Bridge

A reboot of "vcontrol-vitoconnect-bridge service" or whole RPI4 reboot helps than for 1 or 2 days until next stop.

My RPI4:

cat /etc/os-release

I already try this WINGONEER USB zu TTL-Konverter-Modul mit eingebautem in CP2102 and this Hailege 2pcs CP2102 USB 2.0 to TTL UART Serial Converter Module 5Pin STC PRGMR with Dupont Wire but with the same issue.

I'll try the hint from issues 2406 Downgrading to usb 1 (with dwc_otg.speed=1 in /boot/cmdline.txt as suggested in https://github.com/raspberrypi/linux/issues/1187) in the Pi 4

Hope that helps... Does anyone had the same issue and knows a permanent solution?
