Re: LibusbK API clarification for UsbK_ReadPipe

Greetings,

They are synchronous when not used with an overlapped handle.

Yes, if you set a timeout policy for your pipe then these functions will 
return if nothing is received within that time.  If memory serves, it is 
an ERROR_SEM_TIMEOUT but I like to define a macro that checks for a set 
of codes:
#define IsUsbTimeout(errorCode) (errorCode == ERROR_OPERATION_ABORTED || 
errorCode == ERROR_CANCELLED || errorCode == ERROR_SEM_TIMEOUT)

Regards,
Travis
