Re: [Libusb-win32-devel] Problem locating new USB device with filter driver.

[Graeme G. <gr...@ar...>]

Some other problems I've noticed.

After uninstalling libusb (both the filter and non-filter
drivers), and re-installing all the USB plug and play drivers,
my systems USB was operating correctly again.

I then installed the filter driver, and noticed that
the "Unplug/Eject" function of Windows stops operating. This
means that when I want to remove a USB flash stick, there's
no way of telling the system to unmount it. If I do
remove the USB stick anyway, then I get a warning
panel "Unsafe Removal of Device", telling me I
should have clicked on the Unplug/Eject icon in the taskbar,
which doesn't exist!

(This has been bugging me for months. Now I know.
Installing the libusb-win32 filter driver has caused
this problem.)

So it seems that on my system, both the filter driver,
and the filter driver cause problems. The filter driver
stops the Unplug/Eject function from working, but
works well otherwise, and the non-filter driver
kills the whole USB system.
