Use usbtop, it gives a nice overview of what devices are using how much bandwidth:

Bus ID 1 (USB bus number 1) To device   From device

  Device ID 1 :             0.00 kb/s   0.00 kb/s

  Device ID 2 :             0.00 kb/s   0.00 kb/s

Bus ID 2 (USB bus number 2) To device   From device

  Device ID 1 :             0.00 kb/s   0.00 kb/s

  Device ID 4 :             141.73 kb/s 13777.68 kb/s

  Device ID 5 :             9.98 kb/s   11.24 kb/s

  Device ID 6 :             0.00 kb/s   0.00 kb/s

  Device ID 7 :             0.00 kb/s   0.00 kb/s

  Device ID 8 :             141.71 kb/s 15257.26 kb/s

Install and run it like so:

$ sudo apt install git cmake g++ libboost-dev libpcap-dev libboost-thread-dev libboost-system-dev

$ git clone https://github.com/aguinet/usbtop.git

$ cd usbtop

$ cmake .

$ make
