I need to pull apart the Loox720 ROM and inspect the USB host drivers used on that device.It would be nice if HTC reused the basic design for the Axim.
Ok, I've extracted the files from the flash update image for the loox from their support site, but there are only 839 files, is that too little for the entire os, or is that about right?
News update:
I now own an X51v which is much better at running WM5/WM6 than my X50v.
This means I can now look at WM5/6 ROMs from devices that have a built-in USB host port, like the HTC Advantage 7500 series.
Does anyone have a working USB HOST on his dell x50v/x51v and I'm not talking about CF card version... I have read various versions and for those with STF201, but is there a workable model? and can someone to publish it ?
Тhank you in advance!
I'm glad to see that this project still seems to be working. I wish I could help, but my knowledge in this field is rather limited. Would a few paypal bucks help move the project along, or is it more of a development thing?

There are two tasks that need to be done in this order:
1. Verify the client USB port hardware will support USB-OTG
without this, the project is essentially dead.
2. Write a USB-OTG driver - or port one over from another device that uses the same USB interface.

Thanks for the offer but I need to start doing my reverse engineering of the USB client port - which is going to take time.

It means that there is still no working USB HOST on your PDA, am I right? Can I help you with something... I have friends with FS loox 720, n560, Toshiba e800, Acer N310 can take from them FIRMWARE or ROM with these drivers.

If you looked at one of my earlier posts, I compared the top half of the x50v and loox720 (both made by HTC) and they are almost identical.
If you can grab the USb drivers from the 720's rom, that would be good. There are several besides the USB client driver. I have not had time to pull apart the 720 rom I have.
Essentially, I need to find out if the 720 uses the built-in host port (port 1) or if it is using the USB-OTG port. Or, it might be using a 3rd party USB host interface chip.
Since the 720 has separate client and host ports, it most likely does not use USB-OTG. It's either host port 1 on the pxa270 or a 3rd party chip.
I broke out the USB drivers for the Loox 720 and it appears at this point that it might actually use the USB Host Port 1 on the CPU chip. :)
I need to try and disassemble the OHCI.dll to confirm.
Unfortunately, this means it's not for 99% of users as it requires a delicate hardware mod/addition to the motherboard (see my earlier posts & photos in this thread).
The ideal scenario is for a USB-OTG driver and to verify the hardware will support that driver.
Back to the bench.......

Q: How is USB OTG supported in WinCE? What controllers are currently supported?
A: USB OTG is supported on CE 6 and Windows Mobile 5.3 or later. USB OTG is a bus driver which host one USB Function (client) Controller driver and one USB Host Controller Driver according the protocol. The Code we supported OTG on Windows CE 6 is Bulverde(pxa27x) chipset (what the Axim uses) and OMAP 730, OMAP 1030
How about the status of your work now? I have a X51V and appreciate your investigation work about the PDA. I hope your investigation is also useful for X51V. Just keep working!!! :)
PS. I have another idear about the usb host for PDA. I did some investigation on the CFU1U USB 1.1 Host Adapter CF Card and found it's not so difficult to implement the card. I have experiences in using similar function in designing wireless CDMA card. And I've even used the chip before. I think we can at least half the price if we design a card like that. So if someone is interested in this, just contact me. (Mail: rickyqiqi@hotmail.com)

Interesting that it says CE6 and WM 5.3 or later. WM6.1 is still only CE OS 5.2. CE6 is made for other devices. So, does that mean we have to wait till WM7? Seems as what we have now will not work. Next version of WM should be good to go though.
