Hi...

I was able to write data to the device using usb.write() function.In the post 
it says there are 2 ways to read data from the device. I tried to integrate usb 
event handler with VB.net but cudnt compile the Vb application. Is there any 
working example for VB.net using event handler ??? All i want is acquiring the 
received byte array as an event driven function. Please can some1 send me the 
code ? [email protected]

Thank You

Everytime you call "write()" it returns false.
Maybe people have said things about the PTR being wrong, so modifications have 
been made. 
I made those changes, I even removed the hard coding of 64 bytes and made that 
dynamic.
I am still running into problems when trying to send commands to the device.

Hello , thanks for the project , i'm trying to put pieces together but i can't 
made it work. I can connect to the device but as everyone (or a big majority) i 
can't trigger the event handler.

Could you please add a clear example of how to read from the remote ?

thanks !

What steps will reproduce the problem?
1. Windows Form Application keeps running when main form is closed due to 
USBInterface object.
 Attempting to Dispose UsbInterface object by:
 usb.stopRead(); 
 usb.Disconnect();
 usb = null; 
throw NullReferenceException on Disconnect() .


What is the expected output? What do you see instead?
usb Object is Connected and Reading when steps above are executed.


What version of the product are you using? On what operating system?
using MS .NET 2.0


Please provide any additional information below.

What steps will reproduce the problem?
1. When i add to project USBHIDDriver.csproj
2. Or Add the dll to my project
3. using USBHIDDRIVER;

I'm able to instantiate
 USBInterface usb = new USBInterface("VID_04C5","PID_1090");

However when i do the following
usb.Connect();

i get an error that says usb is a field but is used as a type...Can you guys 
help me out on this. Thanks...Yaw
