I haven't used SwingSane and Scarse before. On searching I found following Linux scanning software Although I have Windows machine, Windows 10 Home, but it is running on VM/Guest of Oracle VirtualBox, I expect to connect the scanner to my Ubuntu 20.04 PC which is a fast machine with 8-core AMD CPU, 32G RAM, 1TB NVMe PCIe Gen 3.0 SSD for running the OS and a 4TB WD hard-drive for storage. The bundle scanning software Silverfast SE 8 only works on Windows. I have compared their specification and there is not much difference in their specifications except the software Silverfast SE 8 coming with V850. V800 is already out of market, not easy to find. VueScan is a powerful, easy-to-use program that: -Scans documents, photos and film -Creates PDF, JPEG, TIFF and TXT files -Supports over 1200 scanners' and is a Image Scanner in the system & hardware category.

I'm prepared to purchase a new Epson flatbed scanner V800 or V850 for scanning old film negatives. VueScan is described as 'Third-party software for film scanners and flatbed scanners. My old Epson 3490 is still working on Ubuntu 20.04 PC and the scanning software is XSane. I have been using Epson flatbed scanner for long time.
