Issues related to libusb0.sys for libusb Windows backend. https://github.com/libusbx/libusbx/issues/81 https://github.com/libusbx/libusbx/issues/93 https://github.com/libusbx/libusbx/issues/87 https://github.com/libusbx/libusbx/issues/72 libusbK works better. Still WinUSB is the most mature for libusb Windows backend. > BTW, in order to use libusb0.sys or libusbK.sys with libusb > Windows backend, it is necessary to have libusbK.dll installed. > That should be taken care of by Zadig though. -- Xiaofan ------------------------------------------------------------------------------ Managing the Performance of Cloud-Based Applications Take advantage of what the Cloud has to offer - Avoid Common Pitfalls.
