Hi,
I have bought 7 Micro SD SPI or SDIO Card Breakout Boards in two batches from ThePiHut (I'm in the UK), and 5 of them trigger either "card not found" or "command timeout" on when trying to access them from a Pico using SPI. 2 of them work flawlessly.
I've used the same software, hardware and SD card to test all of them. I'm using 3.3V for power. One of them even makes a weird high pitched sound when turned on. On the software side, I'm coding in Rust and using the embedded-sdmmc and rp-pico crates.
Any idea what I could be doing wrong, or could that be a hardware issue?
Possibly defective Micro SD SPI or SDIO Card Breakout Board?

Also not connecting anything will also trigger this "card not found" error.
