To clarify, i look for something like in the image but mini-B instead of micro.
I converted my cable park to a USB-C cable (male to male) and lots of adapers (the short sort you can keep in a box) years ago. Yet i have still some devices with a mini-B female port.
Only thing i found online are cables and everything else. Heck, there’s even mini-DP > C and ethernet > C in that form factor. Are there technical reasons, like different pins than USB-micro or something?
You might be able to find a USB c male to USB b male cable and do without an adapter entirely.
Been there, always a fumbling behind the PC.
USB hub? I have a spare of USB c, mini, and micro running from a hub to a 3x cable mount on my desk. Makes connecting peripherals a breeze.
