Hi leStoppe,

Thanks for reporting this and bisecting the regression to commit
4cc01410e1c1.

A fix has been submitted to the linux-usb mailing list. It narrows
the OWON match from USB_DEVICE() to USB_DEVICE_AND_INTERFACE_INFO(),
requiring bInterfaceClass=0x05 (Physical Interface Device) as
reported in the HDS200 USB descriptor. This should let the VDS1022
fall back to the generic usbserial driver as before, provided it
uses a different interface class.

The patch can be found here:
https://lore.kernel.org/linux-usb/20260810091322.2201740-1-huangwei@kylinos.cn/

Could you test whether this resolves the issue on your VDS1022?
If the VDS1022 also happens to use bInterfaceClass=0x05, further
work (e.g. a probe callback checking the device string descriptor)
may be needed.
