USB OTG Supported Phones?

I'm looking for Symbian/Android/Windows Phone which support USB OTG. 开发者_StackOverflow社区I Have simple device which send very basic ascii data thro USB and I need to read data in phone application.

Is there any cellphones with USB Host support?

This is a close to complete list. I'm not sure about the android/WP development support for reading those ascii charachters though.

The hardware on the Nexus 1 (like many other phones) supports USB host mode even though the vanilla drivers that comes with it do not.

However, there's a driver available on the net that allows you to turn the support on.See here: http://sven.killig.de/android/N1/2.2/usb_host/ and since it's a Google dev phone "rooting" is a supported feature, not a hack.

Samsung Galaxy S II supports it.

Nokia's Symbian^3 phones support USB OTG 1.3.

To the best of my knowledge none of the current WP7 devices provide USB host support (more than happy to be corrected, though :)).
