Just for information, I have check my small program with FC7 and... same as FC6 , it doesn't work and i have no access to the source code of usb functions, if somebody had an idea...
Thanks
No it's not a config problem (you havn't check my prog on hardware ), to give proof of that I am sending you a program that works well. The problem seems coming from the UsbSlave_CheckRx procedure (i rewrote it)....
