[hpsdr] Much success on winusb in KISS

Sun Dec 20 11:28:09 PST 2009

Jim,
Thanks for that pointer!  I'll check that out!

I've just finished the upload to the K9TRV branch of KISS.  It contains a
number of folders.

Let me enumerate them:
KISS Console - the KISS code, and where the solution file is located
SharpDSP - standard companion to the KISS code
LoadFW - added by me.  Produces LoadFW.exe.  Part of the KISS solution file
LoadFPGA - added by me.  Produces LoadFPGA.exe.  Part of the KISS solution
file 
WriteI2C - added by me.  Produces LoadFPGA.exe.  Part of the KISS solution
file
WinUSBManaged - added by me.  Produces LoadFPGA.exe.  Part of the KISS
solution file.  This is the C# code that is the interface to WinUSB.
WinUSBAPI - added by me.  There is a project there.  You need the Windows 7
version of the Windows Driver Kit (WDK) to build this.  It is NOT part of
the KISS solution file, because not all can build it.  It's included for
illustrative purposes
WinUSBTest - added by me.  Produces LoadFPGA.exe.  Part of the KISS solution
file.  Used to do trivial tests of WinUSBManaged.

Some notes:
You'll need to copy loadfw.exe, loadfpga.exe, writei2c.exe and
winusbmanaged.dll to your various binary directories, such as the USBBlaster
directory, if you switch from libusb0 to winusb for the driver, so that you
can still program the firmware on your Mercury and Penelope cards (and
others) using Ozy as a simulation for a USBBlaster.  Many call this
directory USBBlaster-Binaries.

You also need to copy these small files to whereever initozy11.bat exists,
so that initozy11.bat will work.  The copies of these small files that are
currently distributed with initozy11.bat use libusb0 and need to be replaced
with versions that use WinUSB, or else you have to constantly switch from
libusb0 to winusb and back, WHILE RUNNING, which is not really possible.

These files are already in the bin\release and bin\debug folders of MY KISS
branch, so that it can run.

No warrantee is made as to whether you can run Phil Covington's QS1RServer
at the same time.  You won't be able to run PowerSDR until Bill Tracey
KD5TFD changes PowerSDR to use WinUSB.  Phil C does use the same VID that we
do, 0xFFFE, but uses PID 0x8, where we use PID 0x7.  It is possible that the
PID difference WILL pose a problem if trying to run both sets of code on the
same machine, whether simultaneously or not.

What we need is feedback from people using Vista and Windows 7, ESPECIALLY
the 64 bit versions of those, as to whether KISS now works.

The version of KISS in this branch is the same as Phil Harman VK6APH had
several days ago.  I won't try to track his current changes, which are
mostly for his GigE work with Ozy/Aussie II, the ethernet interface for
HPSDR.  My code should work with Ozy (the original) and Magister.

I think it's time for a beer (Dogfish Head 90), before the bug reports start
rolling in.
Dave KV0S: maybe we need a WinUSB page now on the OpenHPSDR website where we
can keep all these notes and such.  Maybe I'll even have to start blogging
or wiki comment maintaining now!

Vy 73,
George Byrkit, K9trv

That's great George.  I'm looking forward to getting your SVN output for my 
system.

Did you (or anyone else) look at LibUsbDotNet from SourceForge?  Its says
it's 
a package that can be used for either libusb-win32 OR WinUsb without 
changing your source code.  I would like to try it but if anyone else has 
experience with it I would like their input.

Regards......... Jim
