Subject: [BUG] usb-serial-simple: device conflict with Owon VDS1022I
Date: Fri, 6 Jun 2025 17:00:29 +0530	[thread overview]
Message-ID: <6430992c-d50b-4cfd-bcb9-d7d376c53444@gmail.com> (raw)

Hi,

     PATCH 6.1 082/167 adds serial support for OWON HDS200 through the 
simple usb serial driver (). This causes issues with Owon VDS1022. The 
VID and PID is the same for both devices so the the Linux kernel loads 
the serial driver, preventing the associated software from working.

     My current work around for this is to blacklist usb_serial_simple. 
Given that this driver change was recent and still under testing, could 
we find a solution for this that doesn't involve such hacks at my end.

     I  was able to root cause this issue only because the USB device 
and  software was working correctly before. A new user would just assume 
that the device is not Linux compatible.

     I've filed a bugzilla report here : 
https://bugzilla.kernel.org/show_bug.cgi?id=220193

     This is the software : https://github.com/florentbr/OWON-VDS1022

regards,

Amit
