converting an usb.h include file

[Zen]

...Interesting,...
Thanks for the information. And, thanks for alerting us to the possibilities,...
I'll spend some more time reading through all the USDLIB source and info.
...As you are well aware,...this is an excellent concept for a MASM project,...

libusb-win32 setup example source code.

So without proper driver libusb-win32 doesn't find anything ?

[Siekmanski]

You have to install the libusb-win32 drivers for the usb-device you want to communicate with.
With these drivers it only finds those usb-devices.

This is what it shows on my PC,

libusb-win32 setup example.

usb busses count     : 1
usb devices count    : 2

bus-0 VID: 16C0, PID: 05DC
DeviceNumber: 1
Manufacturer: 1
Product     : 2
SerialNumber: 0

bus-0 VID: 0BDA, PID: 2838
DeviceNumber: 2
Manufacturer: 1
Product     : 2
SerialNumber: 3


Press any key to continue...


Those 2 usb devices are my USBasp avr programmer and my just bought RTL-SDR dongle.

Hi guys,
How do I translate this piece of C code to asm ?

a = 5;
b = 7;
c = (a & ~b);

Code Select Expand

mov eax, a
mov edx, b
not edx ; ~b
and eax, edx ; a & b
mov c, eax

[dedndave]

it depends on whether you want "a" and "b" and "c" to be globals or locals
in the case of "a" and "b", they might even be constants (EQU or =)

they might also be arguments of a PROC...

Code Select Expand

SomeProc PROC a:DWORD,b:DWORD

    mov     eax,b
    not     eax
    and     eax,a
    ret

SomeProc ENDP

something similar would be a macro   :P

a = 5;
b = 7;
c = (a & ~b);

   not   eax
   mov   ecx, DWORD PTR a$[rbp]
   and   ecx, eax
   mov   eax, ecx
   mov   DWORD PTR c$[rbp], eax

Thank you very much guys.  :t
