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/[email protected]/ 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. -- You may reply to this email to add a comment.
