Where to download the candleLight driver for Windows?
Thanks!

As far as I know, the gs-usb shows up as a generic WCID device on Windows. You don't need driver on Windows 8 or later. The packets transfered over USB wire are defined here.

@march1993 you are right but there is also https://github.com/HubertD/candle_dll/

is it that candle.dll is supposed to provide a higher level API comparing with just direct USB access?

A bit odd to see this cangaroo here not using https://github.com/HubertD/candle_dll as a git submodule but having a copy (?) of the source code?

rusefillc: If you look into the sourcecode you will see that there are different versions of the code which Cangaroo uses to connect over WinUsb:

Cangaroo uses this code (compiled into the main EXE):
https://github.com/normaldotcom/cangaroo/tree/master/src/driver/CandleApiDriver/api

HubertD uses this code (compiled into Candle.dll):
https://github.com/HubertD/candle_dll/tree/master/src

And Candle.NET uses this code (compiled into Candle.dll):
https://github.com/elliotwoods/Candle.NET/tree/main/Candle

Compare them and you will see that they are all the same code with small modifications.
And Cangaroo does not use a DLL because the code is compiled into the EXE.

But the Candle.dll is not a driver.
Drivers have file extension *.SYS
The Candle.dll only forwards CAN commands to Microsoft's WinUsb.dll which communicates over a Microsoft driver with the CAN adapter. So you don't have to install a driver. The driver already comes with Windows.

Okay but in win 11 after flashing Candlelight - i have 2 unknown devices and no drivers found. Okay i used zadik to install libusbk but cangaroo-win32-ccdcb64cant find any interface now. Only with COM port scl fw working

The Candle API uses WinUSB which does not need a driver. WinUSB is part of the Windows Operating System. You should be able to connect directly with Cangaroo.

STM32G431 controller.

here is offered FW.
After flashing

I have tried 7, 10, 11 windows - same result. MKS CANABLE 2.0 PRO S - can't install drivers automatically. After ZADIG tool - installed, but not working with CANGAROO

This article says clearly that a driver is not required for a WinUSB device:
https://learn.microsoft.com/en-us/windows-hardware/drivers/usbcon/automatic-installation-of-winusb

Install USBLyzer from www.usblyzer.com and study the descriptor. What do you see ?

And what about the SLCAN firmware?
Does this work for you ?
You should see a COM port.

Why do you want to use the Candlelight firmware ?
SLCAN is easier.

I had the same problem as you, did you solve it later? @prounlocks

I have this problem too, cangaroo (both beta and legacy) working with slcan, but not find candlelight device (libusb / libusbK both). and what is Unknown device?

• I try now legacy with slcan, it not find COM port. So legacy all not working
