I have an odd problem.
I have 2 Anker USB 3.0 SD/microSD card readers. They work perfectly when plugged directly into the computer or into my Targus USB 2.0 hub.
They will not work, however, when plugged into the Anker USB 3.0 hub. My first thought is that I simply got a defective USB hub, but the replacement doesn’t work with the SD card readers either. A standard USB thumb drive, however, works perfectly in the Anker hub.
So - the SD card reader works the way it should.
The USB hub is working (at least with standard USB thumb drives) the way it should.
So - why won’t they work with each other? Both are Anker products.
The model numbers of the products:
SD Card Reader - Anker AR200
USB 3.0 hub - Anker A7516
Update - on a whim, I tried an old no brand name or model number on the unit probably came from Big Lots USB 2.0 SD card reader in the Anker hub. It worked perfectly., so it doesn’t appear to be an issue with SD card readers in and of themselves.
