Hi,
sorry to be late on that...
according to the first line of the user's log, libusbx try to use
libusbK drivers instead of WINUSB ones:
[ 0.000000] [00001450] libusbx: debug [libusb_init] created default context
[ 0.000000] [00001450] libusbx: debug [libusb_init] libusbx v1.0.14.10576
[ 0.000000] [00001450] libusbx: debug [init_polling] Will use CancelIoEx for I/O
cancellation
[ 0.036000] [00001450] libusbx: debug [winusbx_init] using libusbK DLL for unive
rsal access
is there's a simple way to remove libusbK driver?

A libusb_open() issue is most likely a driver installation problem.
I tested on Vista 32 with the RC3 binaries and cannot see the issue.
Unfortunately, the FTDI device I use is not recognized by default by
find_all, but I'm definitely having no issues getting the device
strings fetched with xusb.
Can you please test using xusb rather than find_all, to confirm that
xusb also fails? The commands to use:
set LIBUSB_DEBUG=4
xusb -i 0403:6001
If xusb does fail, I would strongly suggest reinstalling the drivers,
as well as providing us the debug log you get.
can you please provide a mingw32 dll with the LIBUSB_DEBUG flag (in case
I do something wrong at compilation stage...).
like that I can send it to try.
Not needed. LIBUSB_DEBUG is meant to be used as indicated above. It
works with the RC3 binaries.
Attached is an example of what I get, with both xusb and find_all,
using an OLIMEX-JTAG-TINY on a Vista 32 machine (NB: this is a real
machine, not a VM).
Regards,
