The micro:bit can be connected to your computer or device with a micro USB cable that is capable of data transfer (not just charging). Data can be sent and received between the BBC micro:bit and the computer so programs can be downloaded from Windows, Mac, ChromeOS (Chromebooks) and Linux (including Raspberry Pi) onto the micro:bit via this USB data connection.
Connect the small end of the cable to your micro:bit and the other end to your computer's USB port. The micro:bit will show up as a disk drive called MICROBIT
You can use a USB hub between the computer and the micro:bit if required
If you don't see the MICROBIT drive...
1. Check that the USB cable is capable of data transfer and try another cable
2. Try another computer
3. See if the micro:bit will mount as in MAINTENANCE mode, by jholding down the power/reset button as you plug it in.
4. Check the operating system to see if the drive has mounted, but isn;t showing up:
Windows - open Device Manager and look under Disk Drives
Mac OS - open Disk Utility from Aplications > Utilities
Chrome OS - Open the Files app.
Ubuntu - open Disks
Raspbian - open File Manager
In each utility the micro:bit should be listed as an external drive.
