Review on TOPESEL 5 Pack 32GB USB 3.0 Flash Drive Memory Stick Thumb Drives - Convenient 5 Mixed Colors: Black Blue Green Red Silver by Paul Dahl

I bought 5 packs of 64GB to put Linux OS images on. When you try to upload images to them, they fail or accidentally get disabled. After troubleshooting, they seem to be very sensitive when connected to USB hubs. When connected to 4 different USB hubs (some powered, some not), they would disconnect or fail to complete the image transfer. Tried to reformat while connected to a USB hub and same errors. When connected directly to the computer's I/O panel on the motherboard, they stayed connected, allowing the drive to be reformatted and images loaded. That issue aside, they work and appear to be a legitimate 64GB. Just picky where it connects.
