USB HID (LPC 2378)

 USB HID (LPC 2378)

I am using LPC2378.I used the example code and its working.
I can transfer a byte to & from the device.
But the problem is that i cannot transfer a block of data from the to and from the device.
In the system side the output report length & input report length is shown as 2.
What could be the problem.
Any help in this matter is highly awaited.

Hello Som Appu,

Please take a look at the application Note http://www.keil.com/appnotes/docs/apnt_195.asp.

In this application note it is also explained how to enlarge the data structure which is transmitted.
