C22-1600 Acer does not see memory sticks,transferring personal stuff using memory sticks not working

I've just bought a C22-1600 All-in-One PC - 21.5in FHD, Intel Pentium N6005, 8GB RAM, 256GB SSD, from Very (to replace 10 YO PC (its Network Adapter died)) with Windows 11.

I can connect an old CD Drive to this new Acer using two USB slots for old games OK.

But regarding transferring personal stuff using memory sticks.

I copy the data to the stick using the old computer OK.

Nothing happens when I plug the old memory sticks in to this new Acer.

My current thinking is my old memory sticks may be too old.

Which memory sticks are compatible with this new Acer All-in-One ?

If you can tell me, I can buy one, and see if that works out.
