Tab S8 Ultra not recognising external card reader

I bought a card reader to use with my S8 Ultra. It had to read CF cards as my DSLR isn't the latest. When I plug it in, it defaults to 'charging device connected' and when I try to change the device controlling the USB, it says 'couldn't switch'. The card reader is connected with a USB-C to USB-C cable.

When I click the USB icon in the top bar, it says 'device not recognised'.

The device in question is a Lexar RW500 professional card reader.

Does anyone have any tips?

Cheers

Have you tried connecting it to another device, a phone or PC and if so does it work?

It works when plugged into my PC, but gives the same result when plugged into my S20+

I may be wrong, but unfortunately I don't believe Android supports CF card readers.

Is your card reader compatible with android devices or just computers?

This isn't stated in the card reader documents. I would have assumed it was as it's only a box with 3 card slots on it.

I think Amazon has it down as compatible with computers only.

I'm having the same problem with a USB-C card reader and a Samsung Evo Plus Micro SD memory card.

 

The tablet doesn't seem to recognise an external card reader. However, if I plug the same card reader into my Samsung Galaxy s21 Ultra smartphone, it works and I can copy the files out. 

 

This seems to be a problem with the Galaxy Tab tablet. 

 

Please fix this issue, Samsung.

I'm having the same problem with my samsung phone and tablet defaulting to charging rather than transferring files. The reader states compatible with Andriod. Did you manage to find a solution as I'm tearing my hair out

Im using an Anker 2 in 1 sd card reader (usb-c), and originally it did work with my samsung tablet, but now its defaulting to charging, so im having the same problem as you. However, when i tried the device with my google pixel phone, it works, and i can transfer photos from my sd card to my phone.
