Hello Everyone,

I am new to this crazyflie environment. I am trying to create windows development environment so followed the instruction mentioned in the Everything was good with the setup on my laptop with OS windows 10, However on my lab pc(windows 7) I Could not able to connect to crazyflie. When I looked at the logs of the crazyflie PC client it was showing a warning like this "WARNING:cflib.crtp.usbdriver:Exception while scanning for Crazyflie USB: function 'usb_find_busses' not found". Here I am attaching the screenshot as well

Note: Installed libusbK(v3.0.7.0) drivers onto my Crazyradio PA USB Dongle using Zadig.

This is strange. A couple of questions:
- Did you install the client the same way on both machines?
- Did you try with the libusb32 driver?
- Are you seeing the Crazyradio in the windows device manager?

Hello Arnaud,

Glad to hear from you, problem resolved after replacing the driver libusbK -> libusb32.

Thanks a lot for your suggestion.
