Tested this code in Windows x64.

If in function OpenHID() add optional parameter "SerialNumber"

x=OpenHID(0, $1234, $1, 2)

the application crashes

[ERROR] Invalid memory access. (read error at address 2)

If pass a pointer to a variable, there is no crash, but the device is not found.

I also noticed that the HID library is missing a function HidID() (similar FileID(), WindowID() etc.).

An USB SerialNumber is a string. (like AARRNIBB9X3FZKXI)
This works without error:

Code: Select all

OpenHID(0, 1234, 456, @"123")

But it looks like a bug, I don't think that this is the intention.

Probably not a string.

Code: Select all

x=OpenHID(0, $1234, $1, "2")

Code: Select all

Line 1: Bad parameter type, number expected instead of string.

Code: Select all

x=OpenHID(0, $1234, $1, @"2")

Code: Select all

Device with requested VID/PID/(SerialNumber) not found

Figured it out. Really need to pass a string - result form HIDInfo(#PB_HID_SerialNumber).

Fixed.
