[Libusb-devel] Is libusb compatible with Windows 7 32-bit/64-bit

[Kari Laine]

Hi,

hopefully some helpful soul takes time and answers me.

After two weeks problems with two of my machines I decided to upgrade
them to Windows 7 (from Vista).
In Vista 32-bit libusb was working fine.

I am now about to test it in Windows 7 32-bit and Windows 7 64-bit.
But before I do,
is it just to run the installer? Does it work both 32-bit and 64-bit?
How about driver signing?
In Vista 64-bit (I heard) one must do a special boot to be able to
install libusb - is it same in Windows 7?

I also heard that people have had problems with USB-mice and keyboards
after installing libusb.
Is this fixed already - if not what to expect? How to go round it?

Thank you for all developers for great work they have put up!

My need is to talk to Velleman K8061-IO board and to Velleman
PCSGU250-scope. Other needs will
certainly surface.

Best Regards
Kari Laine

Firstly it is better to use libusb-win32 mailing list since it is
a separate project. Some of the Mac/Linux people in this
list may prefer not to have too many posts related to libusb-win32.
https://lists.sourceforge.net/lists/listinfo/libusb-win32-devel

Secondly, as of release V1.2.0.0, the driver sign issue is
solved. Now you can use libusb-win32 under 64bit Windows
Vista and Windows 7.

Take note that issue is particular to the filter driver. If you
do not use the filter driver you should be fine.

We think we have already solved the issue of the filter
driver since release v1.0.14.0 release. However, we still
do not recommend to deploy libusb-win32 filter driver
to the end users as of now since it can potentially
conflict with some of the usb device out there.
