# Troubleshooting downloads with WebUSB

Having issues pairing your @boardname@ with [WebUSB](/device/usb/webusb)? Let's try to figure out why!
|
|
|
|
### ~
|
|
|
|
## Step 1: Check your cable
|
|
|
|
Make sure that your @boardname@ is connected to your computer with a micro USB cable. You should see a **MICROBIT** drive appear in Windows Explorer when it's connected.
|
|
|
|
|
|
|
|
**If you can see the MICROBIT drive go to step 2**.
|
|
|
|
If you can't see the drive:
|
|
* Make sure that the USB cable is working.
|
|
>Does the cable work on another computer? If not, find a different cable to use. Some cables may only provide a power connection and don't actually transfer data.
|
|
* Try another USB port on your computer.
|
|
|
|
Is the cable good but you still can't see the **MICROBIT** drive? Hmm, you might have a problem with your @boardname@. Try the additional steps described in the [fault finding](https://support.microbit.org/support/solutions/articles/19000024000-fault-finding-with-a-micro-bit) page at microbit.org. If this doesn't help, you can create a [support ticket](https://support.microbit.org/support/tickets/new) to notify the Micro:bit Foundation of the problem. **Skip the rest of these steps**.
|
|
|
|
## Step 2: Check your firmware version
|
|
|
|
It's possible that the firmware version on the @boardname@ needs an update. Let's check:
|
|
|
|
1. Go to the **MICROBIT** drive.
|
|
2. Open the **DETAILS.TXT** file.<br/>
|
|
<br/>
|
|
3. Look for a line in the file that says the version number. It should say **Version: \.\.\.**
|
|
|
|
or **Interface Version: \.\.\.**
|
|
|
|
<br/>
|
|
|
|
If the version is **0234**, **0241**, **0243** you **NEED** to update the [firmware](/device/firmware) on your @boardname@. Go to **Step 3** and follow the upgrade instructions.
|
|
|
|
If the version is **0249**, **0250** or higher, **you have the right firmware** go to step **4**.
|
|
|
|
## Step 3: Upgrade the firmware
|
|
|
|
1. Put your @boardname@ into **MAINTENANCE Mode**. To do this, unplug the USB cable from the @boardname@ and then re-connect the USB cable while you hold down the reset button. Once you insert the cable, you can release the reset button. You should now see a **MAINTENANCE** drive instead of the **MICROBIT** drive like before. Also, a yellow LED light will stay on next to the reset button.
|
|
|
|
2. **[Download the firmware .hex file](https://microbit.org/guide/firmware/)**
|
|
3. Drag and drop that file onto the **MAINTENANCE** drive.
|
|
4. The yellow LED will flash while the `HEX` file is copying. When the copy finishes, the LED will go off and the @boardname@ resets. The **MAINTENANCE** drive now changes back to **MICROBIT**.
|
|
5. The upgrade is complete! You can open the **DETAILS.TXT** file to check and see that the firmware version changed to the match the version of the `HEX` file you copied.
|

If you want to know more about connecting the board, MAINTENANCE Mode, and upgrading the firmware, read about it in the [Firmware guide](https://microbit.org/guide/firmware/).

## Step 4: Check your browser version
|
|
|
|
WebUSB is a fairly new feature and may require you to update your browser. Check that your browser version matches one of these:
|
|
|
|
* Chrome 65+ for Android, Chrome OS, Linux, macOS and Windows 10.
|
|
|
|
|
|
## Step 5: Pair device
|
|
|
|
Once you've updated the firmware, open the **Chrome Browser**, go to the editor and click on **Pair Device** in the gearwheel menu.
|
|
See [WebUSB](/device/usb/webusb) for pairing instructions.

|
Enjoy fast downloads!
