Q: USB Devices on Macbook

I have a 2015 MacBook, which generally speaking I like quite a bit.  One thing that I have noticed is that when I connect usb devices, I almost always have to reboot in order for the Mac to see the device.  I have seen this problem with a USB scanner, a USB reader for a SD card, and with USB and USB-C external hard drives.  Basically, when I connect the device, there is no response from the MAC until after a reboot.  Note, I have tried a few different USB - USB-C adaptors, with the same result.  I have even checked in disk utility to see if the external hard drives are recognized, and they are not.  I have two different drives I have tried with the same result.

 

If it helps, the SD card reader is in a Juiced adaptor that also has 3 USB ports.  I have tried the hard drives with the Juiced adaptor, and with Apple's USB/HDMI to USB-C adaptor.  I have also purchased a cord that goes from the hard drives directly to USB-C, with the same result.

 

While this is an annoyance I can work around, I am concerned that potentially it will stop working all together, at which point life with my MacBook would be not so good.  Any ideas?

MacBook, OS X El Capitan (10.11.4)
