Remove USB Device Safely Issue

Leo Cheng

Hi All,

I implement the usb mass storage device using uSD card in LPC4357 board and I use Keil USB Stack.

Now there is an issue that the usb mass storage device can't be removed from PC(Win 7). The usb mass storage device should have disappeared after I removed the device safely by clicking the Safely Remove Hardware tray icon.

I assume that the Keil USB Stack would receive a event from hardware driver or ISR anyhow and handle this event. So What I missed?
