[Libusb-win32-devel] end-user error

[Steve F. <ste...@ie...>]

Hi.

I'm trying to use an Atmel AVR programmer dongle on win32 with libusb.
 It came packaged with the gcc (winavr) compiler.

The libusb0.dll file with that one was 0.1.10.1, and it gave the
following errors:

> LIBUSB: error: usb_registry_get_num_busses(): getting hardware id failed
> found 3 busses
> avrdude: usbdev_open(): did not find any USB device "usb"

I just downloaded the newest, 0.1.12.1, and now the error is:

avrdude: usbdev_open(): did not find any USB device "usb"

This device works fine with the manufacturer's drivers/software.  It
also works great with whatever version of libusb I have on my freebsd
6.2 system.  The device apparently works fine with people who don't
have a compaq laptop with libusb0.dll 0.1.10.1.

The usb drivers on my laptop are all standard winxpsp2 drivers looking
in the device manager.  I clicked the "install-filter.exe" in the
libusb download and rebooted, but it didn't appear to do anything.

"testlibusb-win32.exe" gives:
DLL version:	0.1.12.1
Driver version:	-1.-1.-1.-1
bus/device  idVendor/idProduct


Thanks,
