Suggest enhancement to cp utility.

[Steven Friedrich]

I want to know transfer statistics, i.e., max speed, min speed, avg 
speed when I copy to/from a usb device to/from hdd/ssd.
Please enhance cp utility to provide this info.  A cmdline switch could 
request this report.

While shopping for usb cables, I discovered MOST USB cables are only 
capable of usb 2.0 speeds (480 Mbps).

I need more info from utilities and widgets.
Can a usb driver detect the capabilities (transfer speed) of a usb 
device/cable?

The industry is getting away with obfuscation.
