Embedded USB Hosts

I am in the process of choosing a USB host stack for a product my company
is working on.  We are using uC/OS-II on a Sharp ARM9 SoC.  So far we have
narrowed our choices down to:

Jungo's USBware embedded USB host stack.

Micro Digital's smxUSBH embedded USB host stack. 
http://www.smxinfo.com/rtos/usb/smxusbh.htm

On Time's RTUSB-32 embedded USB host stack.
http://www.on-time.com/rtusb-32.htm

I am wondering if anyone here has had any experience with these companies,
or even better, with their USB host stacks.  As far as I can tell they all
appear to be great companies but I would appreciate feedback from users
and customers of these companies with information about what they found
good and/or bad about them and their products.

Thanks,
   Sarain

Hi,

during an Arrow Europe tradeshow, in June, I saw a demo of the "HCC
host-lite" library running on a board made by the Embedded Artists.
The board was the LPC2468 OEM.

The demo showed how the library was able to read/write files (FAT with
long file names) from an USB flash disk.

Look also at Thesycon's USB library. Those guys were selected by
Fujitsu to develop a USB host library for some microcontrollers (FUMA
library is open source but I think the controller is not OHCI
compliant).

I am curious if you checked out Micrium's USB host stack.  Since you
are using their uC/OS, I would think you trust them to also make a
good USB host stack.
