TB2932 shows up as CARDREADER and not a storage device

[Sheila Miguez]

We have a report from someone that the TB2932 device shows up as a cardreader and not a storage device.

It's from the submission for this hardware:
https://certification.ubuntu.com/hardware/202006-27960

I've checked the submission json and it shows up as CARDREADER. I don't know if that's legit what the machine reports to you or if something weird is going on.

I'm attaching the submission.

The following section of `udevadmin info -e` gave indeed a CARDREADER:

The lsblk output:

Note that the main NVME is well reported as a DISK device.

I have no idea what this MMC device really is? a cache of some sort?

All I know from the feedback is: 'It is a built-in eMMC SSD storage device.'
