If the ^^**==red==**^^ LED is ^^**==breathing==**^^, OpenSK is in bootloader mode, this is the simplest way.

Other message line without ^^**==Open DFU Bootloader==**^^ but include 1915:521f and Nordic means it is in normal working mode.

###3. USB Prober.app
####2.2. USB Prober.app
On macOS, if you have USB Prober.app installed, run this app. If you have OpenSK attached and it is in bootloader mode, you should find USB information similar to below picture.
<img alt="OpenSK bootloader mode" src="../images/bootloader_opensk.png" width="900px">
This means it is in bootloader mode.
###2. Linux
On Linux (e.g., Ubuntu), Open Terminal and run
```
$ lsusb
```
No matter your USB dongle is in normal working mode or bootloader mode, the result is always
```
Bus XXX Device YYY: ID 1915:521f Nordic Semiconductor ASA
```
Then run
```
$ dmesg
```
If your USB dongle is in ^^**==bootloader==**^^ mode, you should find below similar output message:
```hl_lines="4"
[ XXXX.YYYYYY] usb 2-2.8: new full-speed USB device number 24 using uhci_hcd
[ XXXX.YYYYYY] usb 2-2.8: New USB device found, idVendor=1915, idProduct=521f, bcdDevice= 1.00
[ XXXX.YYYYYY] usb 2-2.8: New USB device strings: Mfr=1, Product=2, SerialNumber=3

[ XXXX.YYYYYY] usb 2-2.8: Manufacturer: Nordic Semiconductor
[ XXXX.YYYYYY] usb 2-2.8: SerialNumber: FFCCAE942A17
```
Otherwise, if your USB dongle is in ^^**==normal working==**^^ mode, the output message should be similar to
```hl_lines="4"
[ XXXX.YYYYYY] usb 2-2.8: new full-speed USB device number 22 using uhci_hcd
[ XXXX.YYYYYY] usb 2-2.8: New USB device found, idVendor=1915, idProduct=521f, bcdDevice= 0.01

```
!!! note "NOTE"
You'd better to use `sudo dmesg -c` command instead of `dmesg` to output latest new added message after you plug in and plug out the USB dongle.
