USB Host On Evo?

---

sven.killig.de/android/N1/2.2/usb_host/ This method enables you to host usb devices from your Nexus 1. Is it possible do this on Evo also?

Looks like it might only be for Froyo, but then again not sure.

He writes it should work for 2.1 but even for Froyo (custom ROM ) it would be great

I am working on a few custom roms right now but when I'm done with that I'm gonna start working on some kernels including this exact feature.

MOD EDIT - Moved to Q&A

my question is "does the hardware of the evo support usb host mode?" I know the evo shares a lot with the nexus one and other current gen htc phones so I'm hoping so.

BUMP!

omg please... anyone have the gear to try this... i guess im gonna have to take some stuff apart..

If/when you are ready, let me now. I have keen interest in this.

Here's what I know:

1) The EVO has no power supply to power the USB device (so you will need a powered hub or cable hack).

2) HTC loves to (seemingly) use the fifth pin as a way to know that the car charging dock is in use so there is a strong possibility that auto-sensing a USB host cable will not work; it will have to be entered via software in some other way. It could be that this switch is actually HTC's own software running and detecting it; I've never dug in enough to know.

3) The Snapdragon processor has the hardware to support USB host and there is a project that Qualcomm has to support the features of their processors witih Android which is (presumably?) where these drivers came from: https://www.codeaurora.org/xwiki/bin/QAEP/

I'm willing to support such a project with my (limited) knowledge and cash. Let me know who's interested

I have the micro-usb to female OTG cable on it's way, and a powered usb hub that i'm gonna hack. from there, as long as the kernel has support and there are modules to load...

I've done this. There is no built-in support on Android 2.1 or 2.2 from HTC on the EVO. At least no support for flash media. We will need to add the driver from here (or something similar):

HTC HD2 Kernel with support for USB Host. Same processor and probably similar internals, too. I don't have to the time to get up-to-speed on downloading/building/deploying kernels (and I'm not rooted, yet, on the EVO). I have an HD2 and I might try their stuff on that as it looks like it's "done" so I can see how well it works (or not).
