Are there any good examples for the use of FreeRTOS as USB Host, preferably on ARM7 cores?  
I’m looking for an ARMx with USB Host capability to interface an USB memory stick.

I could go with ucLinux but I think that would be overdressed

Are there any ARM7 MCUs which provide an USB host other than Sharp lh7952x that you are aware of?  
I think it is quite uncommon on an ARM7.

Pls take a look on the Demo/lwIP\_Demo\_Rowley\_ARM7

FYI, Demo/lwIP\_Demo\_Rowley\_ARM7 has a USB device example, not host.

OK, besides choosing a suitable MCU or an USB Host chip:  
Does anyone have examples how to use FreeRTOS as OS for an USB Host, especially with FAT storage support

Of course I know there are USB examples, but these are, as already said, USB Device examples
