I'll lookup the mail thread and reply t= here as well. 1. I use this software : https://github.com/florentbr/Owon-VDS1022 What you said is exactly what is happening. This software uses libusb to access the VDS1022. The breakage started when the kernel automatically sta= rted to load the usb-simple-serial driver. The application could access it only after I blacklisted the driver. 3. The VDS1022 supports some SCPI commands. I can enable the socket for it = via the userspace application above. I'm not sure the command set is same as HD= S200 or if it can be done through the serial interface instead of libusb 2.
