So I rebuild release 3.1.0.0 source with latest VS2026 and it has the same issue. Somehow the compiler changes makes the kList application no longer works, strange.

Looks some compiler optimization may create issues. Or there are some 32bit/64bit thingy.

Debug version of kList x64 seems to run but then never stops. Same for Release/Debug version of kList Win32.

Release version of kList x64 will say "invalid selection".

And if I use WDK 7600.16385.1 to build libusbK 3.1.0.0 release, there are no issues with kLIst.

From Google Gemini.
++++++++++++++++++++++
Here are the complete, consolidated changes required to fix kList and the device selection logic for modern Visual Studio toolchains (VS2022/2026).

1. The Macro Fixes (Resolves the Infinite Loop)
   In your header file where the descriptor validation and advancement macros are defined, update them to explicitly reject structures with a bLength of less than 2. This acts as an immediate circuit breaker when the parser hits compiler padding or a zero block.

Replace the old definitions with the following:

// Force validation to check for a minimum header length of 2 bytes
#define IsDescValid(DescriptorPtr, RemainingTotalSize)\
	(((RemainingTotalSize) > sizeof(USB_COMMON_DESCRIPTOR)) && \
	 ((DescriptorPtr)->bLength >= 2) && \
	 (RemainingTotalSize) >= (DescriptorPtr)->bLength)

#define IsUniDescriptorValid(DescriptorPtr, RemainingTotalSize)\
	(((RemainingTotalSize) > sizeof(USB_COMMON_DESCRIPTOR)) && \
	 ((DescriptorPtr)->Common.bLength >= 2) && \
	 (RemainingTotalSize) >= (DescriptorPtr)->Common.bLength)

// Prevent 0-byte advancement by forcing RemainingLength to 0 if bLength is invalid
#define AdvanceDescriptor(DescriptorPtr, RemainingLength)										\
	{																								\
		if ((DescriptorPtr)->bLength < 2) { \
			(RemainingLength) = 0; \
		} else { \
			(RemainingLength) -= (DescriptorPtr)->bLength;													\
			(DescriptorPtr) = (PUSB_COMMON_DESCRIPTOR)(((PUCHAR)(DescriptorPtr)) + (DescriptorPtr)->bLength);	\
		} \
	}

#define AdvanceUniDescriptor(DescriptorPtr, RemainingLength)										\
	{																								\
		if ((DescriptorPtr)->Common.bLength < 2) { \
			(RemainingLength) = 0; \
		} else { \
			(RemainingLength) -= (DescriptorPtr)->Common.bLength;													\
			(DescriptorPtr) = (PUNI_DESCRIPTOR)(((PUCHAR)(DescriptorPtr)) + (DescriptorPtr)->Common.bLength);	\
		} \
	}

2. The main() Input and Reset Fixes (Resolves invalid selection and the Trailing Driver Error)

In your main function source file, update the selection variable declaration to match the scanf_s bit-width, clean up the comparison check, and introduce LstK_MoveReset before the second loop pass.

Step A: Update Variable Declarations
Change selection from LONG_PTR to UINT:

// Inside main()
LONG ec = ERROR_SUCCESS;
KLST_HANDLE deviceList = NULL;
KLST_DEVINFO_HANDLE deviceElement;
LONG devicePos = 0;
UINT selection = 0; // Fixed from LONG_PTR to prevent x64 stack/register corruption
UINT count = 0;

Step B: Refactor Selection and Reset the List Cursor
Replace your input block and the start of the second device list loop with this corrected sequence:

	printf("Select device (1-%d) :", (int)devicePos);
	while (_kbhit()) _getch();

	// Clean 32-bit width match for %u without legacy casts

3. Targeted Optimization Fix for kList.c (Optional Insurance)

If you encounter any remaining edge cases in x64 Release builds where pointers inside kList.c get cached incorrectly due to strict aliasing rules, add this compiler directive to the very top of libusbK/src/kList/kList.c:

#if defined(_MSC_VER) && (_MSC_VER >= 1930)
// Prevents global register allocation from miscompiling legacy pointer casts in this file
#pragma optimize("g", off)
#endif

It helps, but there is an extra line "A device attached to the system is not functioning." in the end.

Google Gemini free version got some idea but I was not able to fix the issue with its help.

@Youw,

Just wondering if you can ask Claude to help here. Thanks.
