Hello Everyone,

I am new to this crazyflie environment. I am trying to create windows development environment so followed the instruction mentioned in the https://wiki.bitcraze.io/doc:crazyflie:dev:env:windows. 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.

Thanks,
Hari

Hi,
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.
