Bug Report: Minor errors in USB Host code

Hi,

I'm reviewing the changes in MQX 4.1.0 and spotted a couple of minor errors in the USB host code - (actually I am using v4.8.4 of the GCC compiler and these come out as warnings):

usb_host_msd_bo.c Line 109 -

   USB_mem_zero(intf_ptr, sizeof(USB_MASS_CLASS_INTF_STRUCT_PTR));

Looks like this is a typo - the intp_ptr is a pointer to a USB_MASS_CLASS_INTF_STRUCT, so it looks like the intention was that the whole structure be zeroed, where as in reality only the first 4 bytes are being zeroed.

Same thing in usb_host_printer.c at Line 468

   USB_mem_zero (prt_intf,sizeof(PRINTER_INTERFACE_STRUCT_PTR));

I don't think these are going to cause any problems, but I figured if you are still using version 4.7 of the compiler you might not have see these, and they look like quick and easy fixes.

Thanks

Chris
