iPhone 2g not charging or recognized by computer

I have an iPhone 2g in recovery mode that I want to restore to iOS 3.1.3. When I connect it to an outlet it charges fine, but when I connected it to my 2019 MacBook Pro it does not charge or is recognized. I have windows 10 boot camp installed so I tried that with the same results. Since I only have usb c ports on my Mac I had to use Apple’s adapter, I thought that might be the problem. I have a 2009 Dell which I tried and still didn’t connect. I have an iPhone 4 that uses the same 30 pin connector, and that works just fine with everything I tried. Please let me know if you have any suggestions because I am out of ideas.
