i'm using lpx4357 and successfully completed keyboard interfacing using USB HID but when i connect a barcode scanner hard fault occurs after scanning .. only one byte read / detected and then it goes to hard fault.. can i get some ideas why this could be happen?? or any suggestions ?
Is your project based on lpcopen demo ? if yes which one? any revise ?
Please track where runs to error? Does it enumerate well?
issue solved .. thank you..
