I'm using MQX 4.1.1 with TWR-VF65GS10 (Vybrid), under IAR Systems platform; I'm trying to make the example MFS_USB ("...\Freescale_MQX_4_1\mfs\examples\mfs_usb") to work, in order to read flash drives.
As I already use the USB0 as a device, I changed "twrvf65gs10_a5.h" to use USB1 as host:
The problem is that, if I run the example without the flash drive and then attach the drive, it's mostly not recognized. If I start the example with the pen drive attached, ok, it's recognized and works fine, but, if I disconnect it and reconnect it again, it's not found again (most of times).
In other words, the "USB_ATTACH_EVENT", in many times, doesn't happen, in 'USB_task()', in module 'usb_task.c'.
