I see not,at the beginning I didn't install any driver for my usb device,just level it as windows installed. However how did the pyusb/libusb-windows backend find it and get the device/interface descriptor for it with out winusb? the device is an mass storage device.
Currently the libusb-win32 seems to be an better choice with filter-driver if it works... 2010/9/11 Xiaofan Chen <xiaof...@gmail.com> > On Fri, Sep 10, 2010 at 11:54 PM, Wander Lairson > <wander.lair...@gmail.com> wrote: > >> > 'Manufacturer:',dev._ctx.backend.get_string_descriptor_ascii(dev._ctx.handle,dev.iManufacturer) > >> The dev.set_configuration() itself also raised the : > >> usb.core.USBError: Operation not supported or unimplemented on this > platform > >> > > > > Have you installed your device with WinUSB? > > Yes, in order to be able to carry out meaningful operation (other than > reading > descriptors), then WinUSB driver needs to be installed for libusb-1.0 > under Windows (unless the device is an HID device). > > http://www.libusb.org/wiki/windows_backend > Zadig can be used for driver installation. > > Also take note that WinUSB does not support Windows 2k, 64bit XP > and 32/64bit Windows 2003. > > In the future, there will be a libusb0.sys (libusb-win32) backend for > libusb-1.0 > under Windows. > http://www.libusb.org/ticket/49 > > > -- > Xiaofan > > > ------------------------------------------------------------------------------ > Start uncovering the many advantages of virtual appliances > and start using them to simplify application deployment and > accelerate your shift to cloud computing > http://p.sf.net/sfu/novell-sfdev2dev > _______________________________________________ > pyusb-users mailing list > pyusb-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/pyusb-users > -- It's a long journey to go! :-) Legend since 1985...
