And one other thing I've found, but I have no explanation for...
Sometimes you cannot use an intermediate USB hub. I have a Dell XPS
8930 and Pixel 4a. I also bought a USB 3.0 Hub with power ports for
charging from my desktop,
<https://www.amazon.com/gp/product/B075NMVGP7>.
When I want to use adb, I have to plug the phone directly into the
computer. When the phone is directly plugged into the computer, 'adb
install <apk>' works as expected. I can also transfer pictures.
When plugged into the hub, I can only install small apk's. If the apk
is too large, then I get an error when running 'adb install <apk>'.
You may experience the same or a similar problem with large file
transfers.
Like I said, I have no explanation for it. I just know it happens.
When I experience it, I plug the phone directly into the computer.
