Hi,

I am getting the following error when running this line: python crazyradio-firmware/usbtools/launchBootloader.py

the error reads:

Traceback (most recent call last): File "crazyradio-firmware/usbtools/launchBootloader.py", line 95, in <module> sys.exit(launchBootloader(True)) File "crazyradio-firmware/usbtools/launchBootloader.py", line 42, in launchBootloader dev= findDevice(0x1915, 0x7777) File "crazyradio-firmware/usbtools/launchBootloader.py", line 33, in findDevice busses = usb.busses() File "/home/randychen233/.local/lib/python3.8/site-packages/usb/legacy.py", line 355, in busses sorted(core.find(find_all=True), key=lambda d: d.bus), File "/home/randychen233/.local/lib/python3.8/site-packages/usb/core.py", line 1309, in find raise NoBackendError('No backend available') usb.core.NoBackendError: No backend available
