Cannot boot from MXT USB2 uSD card reader

[procount]

Describe the bug

This USB card reader works fine in Raspberry Pi OS, but it is not recognised by the USB boot loader.

Steps to reproduce the behaviour

Tried booting a working uSD card using this adaptor on USB2 and USB3 ports of Pi4 and Pi5. Neither recognised it. It booted straight away when I changed the adaptor for an Integral USB3 adaptor. The diagnostic screen reported: "MSD error [01:00] 2.00 000000:01 error 2"

Do you have a link to the product?

I bought 2 Integral USB3 card readers from amazon https://www.amazon.co.uk/gp/product/B07PN54VQ2/ to replace one I lost. These work fine on the RPi (prolific), but wouldn't work on my Win10 laptop (well, they worked, but they kept disconnecting after a few 10s of seconds.) So I bought this USB2 card reader from ebay, which worked fine on my laptop and in Raspberry Pi OS, but wouldn't work in the RPi boot loader.

@procount Please could you try these bootloaders (flash using rpi-imager). I tweaked the order of the MSD operations because some SD-USB adapters don't wake up until after read-capacity has been issued.

[timg236]

A better fix - the previous version caused an issue with multiple slot SD card readers where the card was not in LUN0

Sorry Tim, my original SD card reader has stopped working altogether, so I can no longer test.

No problem. Closing as fixed.
