I purchased the reader and when I insert it into any of my computers Windows 11, Debian 11 none of them recognize the emmc module. Etcher, et al, do not show any available flash devices. Am I missing some device drivers or should it just work? I have 3 CoolPi's and I've tried all the adapters and emmc modules.

Thank you. This is my first time working with emmc.

How do you flash this onto the emmc? Can anyone outline the steps in English? Thanks in advance.
