I know there are several USB hub dongles that could be used in a similar manner, but what I’m looking for is something that occupies a single USB port and offers 3+ slots for SD and/or microSD cards, letting me browse them all from my computer. Are there any such products? I’m ok with buying off Aliexpress
The second link had 4 slots, but do you mean 4 slots of the same exact type?
Yes. I already have one of those multi-type/universal card readers. That is not what I’m looking for. I need something with several identical slots, either for SD or microSD cards
