What version of libusb-1.0?  Ideally, a commit hash would help here...

Turn on debug logging?

Are you using the version from Cygwin? If that is the case, it is
quite an old version. As per Pete, it is commit
03e9371a460031dcb599a1cf504539667cf12f1c,
that is r153 (2010.02.06).

If possible, try to update the the later version.
For example, the latest snapshot is here.

Re: libusb-1.0 windows backend now in Cygwin packages


yes. I used the version from Cygwin, the library file name as libusb-1.0.a
I use the latest Cygwin setup.exe to install and update.

Re: libusb-1.0 windows backend now in Cygwin packages


Hello XiaoFan:
I am really confused by those information. 
since winusb package includes winusb.dll adn winusb.sys, why I need install
libusb.1-0 again ?

I refer to http://www.libusb.org/wiki/windows_backend,  there is less
information about how
to install libusb under Cygwin, it seems to be related wth GIT. 

After download the latest libusb_2010.03.30 package, I even cann't run
LSUSB.EXE and XUSB.exe.
it lack something or old version reason.

Would you provide some help for me ?
1. how to install latest libusb library files ? and where is it downloaded?
I only find linux version!
2. how to compile it ? Do I need install MingW ?

I see. Maybe you want to try the latest git tree. Install git and
other tools (automake, autoconf, libtools, gcc, etc) from Cygwin
and then you can build the latest git tree. Or you can use the
latest binary snapshot from Pete.

Re: libusb-1.0 windows backend now in Cygwin packages


I have updated latest GIT version 1.6.6, but same result also happen.

I need to know if it is necessary to install WINUSB.SYS and WINUSB DLL file.

It has nothing to do with the version of the git executable.  You need the
latest version of the git *repository*.  If you have difficulty with that,
you can just use the gitweb interface and grab a source tarball.

http://git.libusb.org/?p=libusb-pbatard.git;a=commit;h=66192f7b43985dbb4f565
cce38187ee08749fdc0

and click the "snapshot" link.

file.

Yes.  Don't forget to edit the inf first, per the instructions.  If you wait
a little while, Pete may make this easier with the wdi utility, but it still
won't be part of the official distribution for awhile.

Re: libusb-1.0 windows backend now in Cygwin packages


Hello Micheal:

since MS provide a whole of WINUSB api, WINUSB.sys, WINUSB.dll, why do we
need install
libusb library under Cygwin ? and it seems that application should call
libusb_1.0 library. Does
it call WINUSB.dll ?
I only find WINUSBxxxxx.dll under ddk, not WINUSB.sys, it is build in OS
intall binary package ?

As you said, I should do as following: 
1. download libusb-pbatard-66192f7b43985dbb4f565.tar.gz from Repository, and
install it under
    Cygwin, right ?
2. install WINUSB.sys and WINUSBxxx.dll under windows? right ?, but where
can I get WINUSB.sys?

Thx for your help

Re: libusb-1.0 windows backend now in Cygwin packages


Hello Micheal:

I download the latest busb-pbatard-66192f7b43985dbb4f565.tar.gz,build it
successfully.
and also compile "lsusb.c" under example , but after run "lsusb.exe", there
is no message show.
I try it under linux, "lsusb.c" will enumerate all USB device/controller.

my computer OS is XPSP2, I cann't find WINUSB.SYS under driver folder. How
should I do now ?
upgrade to SP3?

I plan to run "lsusb.exe" normally that doesn't desire any own usb device,
so it is not necessary 
to modify INF and install ? right ?
