Firmware update is stuck at putting device into DFU

I am using an ODrive 3.6 and am trying to update the firmware from v0.5.4 to v0.5.6. When I ran odrivetool dfu, it gets stuck here:

Waiting for ODrive...
Checking online for latest unknown device firmware on channel master...
Found compatible firmware (0.5.6). Install now? [Y/n] y
Downloading firmware...
The device may have user configuration that will be lost after the firmware upgrade. If you want to back this up please run `odrivetool backup-config` first. Do you want to continue anyway? [Y/n] y
Putting device 207F37815753 into DFU mode...

Is it safe to cancel the script and try again?

Unplugging and plugging back in the USB resolved the issue. I should have read the documentation more closely.
