Also, any chance you could recommend a brand of solder on the amazon.co.uk site :lol: Looks like you'll have an easier time finding solder with lead in it on UK eBay than Amazon. Also get a brass wire soldering iron tip cleaner like the example below. They work better than a wet sponge. https://www...

Also, has that particular usb-serial adapter worked in the past or is this the first time it's been used. Try another driver. Or try a different usb-serial adapter (e.g. FTDI vs Prolific) & driver.
