USB error in Debug Mode

[zerondeau]

allo ,

Delphi 2007 and delphi XE on a   OS win7 x64

using a Microchip Pic32 in FULL speed


I have update my libraries from 9.15 to 9.17 and I have noticed that when I'm debugging
my application , I always have some errors from the pipes.



when I use nrUsb.sys     , it's return  ERROR_IO_PENDING
error come from  : 
function TnrSysUsbApi.DriverCall(code: dword; ptrOut: pointer; szOut: dword;
   

when I use WinUSb.sys  , it's return  Read or Write ERROR
error come from :
function WinUsb_ReadPipe(InterfaceHandle:dword; PipeId:byte;
function WinUsb_WritePipe(InterfaceHandle:dword; PipeId:byte;

 
all IN/OUT packets are transferts with my USB interface (test also with a USB sniffer and everything seem okay)

is it a problem or just a flag err when I'm debugging ?

Hello

It is not a error.

It is garbage debug output of handling the overlapped I/O operation.
We will remove this debug message in the next release.
