Support usb drive or card reader

[leaked]

Hello

First, thank you for your efforts
In windows, I can't write on usb or card reader
It does not recognize anything at all

> fwup -z
fwup: No memory cards found. Try reinserting the card.

Because I need WiFi credentials, that's why I want to use fwup

Thanks for letting me know about this. Can you tell me more about the version of Windows that you're using, whether you're using a USB or built-in card reader? Also, do you know the path to the MicroSD card that fwup should have detected?

System : Windows 11 Version 10.0.22000
Micro SD : PNY 32GB Class 10
Card reader : Oscar
USB 3.0

I don't know the sd card path for fwup, but I know my F:\ drive belongs to sd card

Thanks. I'll try to reproduce. Since this might take a while, you should be able to get past this by specifying -d microsd.img where the microsd.img can be any file name. fwup will write the image to the file and then you can use Etcher or another program to write the img file to the MicroSD card.
