Re: [Libusb-win32-devel] lots of bugs (Carl Kenner)

[Carl K. <car...@gm...>]

I'm using the latest version you can download.

I reckon I'm going to try this:
  Open the device
  try reading the feature report
  if that fails then
    call usb_setconfiguration
    try reading the feature report again
  end if

  every frame try reading the input report using usb control messages

  close the device

But on this vista computer, reading the feature report without setting
the configuration always fails. Hopefully with the filter driver,
reading the feature report will work the first time, so it will never
call usb_setconfiguration and thus never lock up the computer forcing
them to reboot. But I haven't tested that yet.
