GetVersion function is fine, but the Update furnction does not work. Please help! thanks. I am using the original VirtualDevice_MCU.offer.bin and VirtualDevice_MCU.payload.bin as my input files.

Hi Hub, The issue is that the tool only uses HID_SetOutputReport(). But this option does not always work. The tool must be modified to support WriteFile(). Please see here: https://learn.microsoft.com/en-us/windows-hardware/drivers/hid/sending-hid-reports Later we will modify the tool to support both options, or you submit a PR for it.

Hi Sam,

Thank you, After using WriteFile instead of HidD_SetOutputReport, and adding one missing GENERIC_WRITE flag in the CreateFile handle for this out report, this tool works good here, wonderful.

Glad to have you and your team's strong help here.

Thanks again.

Hub
