I have a USB to RS-232 unit with eight ports. I can attach its ports to WSL2 and see all eight ports as ttyUSB0 - ttyUSB7. After a while however, the ports disappear from WSL2! I have to reattach them in PowerShell using usbipd. Is there any way to keep the ports attached to WSL2?

Not having a make and model number of the adapter makes it hard to visualize it, have seen single-port cables. One thing to check is that Power Options are not turning off the USB ports on the computer if not seeing activity.

It's a Gearmo GM-FTDI8X-M. There are no power options for it in Device Manager. As long as I just minimize and don't close the WSL window the connection persists so I guess that's what I'll do.

The Power Options used to be in Control Panel but now in Settings, Power. Main thing is for keeping the computer's USB ports active so the devices plugged into them keep working.

I don't see a power unit in this image, can't determine if it uses commercial power or relies only on USB ports.
