    Hey guys,

    I'm using the MacBook Pro 15-inch late 2016 for about three month. The version of the operating system I'm currently on is macOS Sierra 10.12.4. Recently, I use the Apple USB-C to USB-A adapter to connect my hard drive disk (Seagate Back Up Plus Slim 2Tb for Mac). Everything just went okay. However, when I use the same Apple adapter (USB-C to USB-A) to connect the usb flash drive (HP v250w, format: FAT32), I found out that my MacBook Pro "cannot" even read it! It just didn't show up in Finder Sidebar , desktop, or even in Disk Utility. No matter what I've done such as rebooting, restoring SMC, this problem just cannot be solved. (I am sure that the usb flash drive is working because I can read it with my windows 8 computer)

    Am I the only one who has this problem? Please help me! Thanks a lot!

    Yes, it can also work well with the usb-ethernet adapter, etc. Somehow it just cannot work with usb flash drive.

    The HP v250w is known to not work right (or at all) with Macs. Try another model or brand.
