Cool thing is that it’s platform-independent. No code changes Regards, Travis 2. Please let me know if you know sources where I can find these informations. The close DLL function calls the “release” and “reset” functions. However, you can specify only one of these options for a particular function, not both. I’ll shorten the question.

Message 7 of Dave, I have never tried this personally. If simultanous use is required, then you really need a true device driver. Tried install-filter with different parameters – no luck. But this does not mean libusg in the community have not have more success, so hopefully someone else will find this thread kibusb be able to help you!

Funny timing, I just completed the same thing yesterday. The tutorial linked above is pretty old, and based on the comments at the bottom of that page it isn’t as thorough as it maybe should liubsb. This is generally not an issue unless working with ‘composite’ usb devices that implement more then one interface s intended to be accessed by different programs.

The only way I was able to detect devices at all was to libsub the inf-wizard. On top of WinUSB. The close DLL function calls the “release” and “reset” functions. Sign up or log in Sign up using Google. When this library is installed, it substitutes the current USB device driver in Device Manager with its own custom libusb-win32 driver.

It looks just like someone unplugs the UPS USB cable and plugs in again but there is no indication of any actual disruption in physical connectivity. My initial plan was to write four functions, one function that does the init, find busses, find devices, claims the interface, sets the configuration and sets the alternate configuration.

During my investigation of “Data stale” error of NUT, I open Device Manager and I see that “libusb-win32” device is disappearing and appearing again every 30 seconds approximately. This way you can abstract away any incompatible structs, handles, etc. I’ve faced a problem getting my libusb-w32 based program to detect devices.

Why does my PIC32 run slower than expected?

Better yet does anyone have any sample code doing this? But the word around here is that this can be extremely difficult and the few people I know who have tried to challenge power of the win32 hardware Dlls have had many problems.
