How to use USB Host MSD

I want to use a USB memory stick, so the end user can plug one in and out,

I have looked at this code, and CANNOT work out how to use it, in the same way as the SD lib.

This has been in beta for some time, but still no development ?

Please can someone help.

Cheers

I'm using the USB Host MSD - http://developer.mbed.org/users/neilh20/code/kl25z_Usb_Logger/ The variant I'm using http://developer.mbed.org/users/neilh20/code/F401RE-USBHost/ is a fork of Norimasa Okamoto and I've tested it on a Freescale KL25z for reliability and working up to using it on K20D. It requires the USB Stick to be plugged in to initialize - and I need to start to figure out why. A big thankyou to Norimasa for publishing the core - and now it needs to have some event wrappers round it. I need to try https://developer.mbed.org/handbook/USBHostMSD to see how well it works.

I've just started playing with this and have the same issue with the USB stick needing to be plugged in at the start to initialise. Did you ever manage to remove that necessity?
