crazyradio dongle not seen

[sensor]

I am attempting to update my crazyradio firmware but am having problems.

1. started crazyflie client
2. per instructions,
crazyflie -> bootloader
3. initiate bootloader cold boot, then startup crazyflie

but it says "Cannot find a Crazyradio Dongle".

I did install a driver for the crazyradio (I did not write down which one so not positive on that; I assume it defaulted and I took that one. Also in "Device Manager", I don't see the Crazyradio dongle). I'm on a Win7 64bit system. As far as drivers the zadig s/w indicates choices among:
(a) Win USB (libusb)
(b) libusb-Win32
(c) Win USB (Microsoft)
(d) libusbK (v3.0.6.0)

I assume libusb-Win32 isn't one I should try since I'm on a 64-bit system or am I wrong in that thinking?
If that driver is not the right one, which driver do you recommend?

Hi,

libusb-win32 is the driver you should use. I guess it is called win32 for historical reason but it is also a 64bit driver.

I guess you mean that you want to update the Crazyflie, the procedure you are describing will update the Crazyflie not Crazyradio.

Best Regards,
Arnaud

Hello,

seem I have a problem with libusb driver (from Zadig),

in Help -> About -> debug : cannot find a Crazyradio Dongle

I try to install it on Win8 - 64 bit. No GoPro drivers installed.
Tried to install, reinstall, reboot. No success.

What can I do now ? What should do the leds on crazyradio dongle ?

Any help is appreciated.
