Not able to find device on Windows but I can find it on Linux

[krazak]

Hello,

When I enumerate devices on Ubuntu via VirtualBox, I see the specific device that I'm looking for. However, when running the HIDAPI code on Windows, it does not find the device. One thing that I have to do in Ubuntu before trying to discover the device via HIDAPI is to run the command: sudo chmod -R 777 /dev/bus/usb. Do you know why I maybe having this problem on Windows?
Thanks.

Have you enabled the device pass through on Virtualbox? That is, can lsusb see it?

Oh sorry this is about Windows. Is there a Windows driver installed for this device or is it a mouse or keyboard? In either case hidapi cannot access it then.

Thanks for the response!

There is no Windows driver installed for it nor is it a mouse or keyboard. This is a custom HID device that I've built on an ARM processor using some of Atmel/Microchip's ASF (Advanced Software Framework) boilerplate code.

I've just noticed an issue with the USB traffic using an analyzer. I'm not sure why this is working on Linux but failing on Windows though.

The device failed to enumerate under Windows, so HIDAPI is not even in the picture in this case. You have to fix your FW.
