is it true what i heard, that wizard supports usb hosting? what i understand it means, it would be pluging usb drive to wizard usb through some kind of usb mini adaptor and accessing this drive through wizard? is it true? any special cable required or just mini 2 mini usb?
Not true. Search the forum.
thanks hanmin i did, just wanted do make sure.
i got confused by the usb host drivers floating around...
so should i understand these ar ment for other then wizard wm5 devices, or is it generally not true?
Good if you can point out where you get to know about this.. usb host drivers.
As far as I know, it is not true for all current devices discussed in this forum. If it were to be true, I think I would have known it as it is a rather big 'feature'.
this url http://www.deje.gmxhome.de/software.html was mentioned by someone asking similar question in this thread
http://forum.xda-developers.com/showthread.php?t=270117&highlight=usb+host+wizard
if you scroll down the page you will read
"This is a driver which enables you to use USB mass storage devices (HD, multimedia Reader, digital camera) with your USB host enabled PocketPC."
that's exactly what i'm unsure of, are there any usb host enabled PocketPCs?
in addition here's a place where i first read it's possible
http://pdaclub.pl/dl/file_view.php?f_cat=92&sortby=t&sort=asc&f_id=530
unfortunately it's in polish, so no use for you guys. It states that
"WM 2003 SE original built in drivers allow you to use most generic usb storage, digital cameras, and even usb keyboards..." this site doesn't give any details about authors homepage, but mentiones that its the same guy who did MPointer (usb mouse plugged to pda)
don't really know what to think about it... enlight me
Interesting... it seems to be working on some PDAs...

Hmm.. you can try the suggestion here
http://pocketpcmag.com/forum/topic.asp?TOPIC_ID=13738
But, I still think the current units discussed in this entire forum can't do it.
Thats what i ment. there are rumors it could work... but until i'm sure, i think i'll pass... i'm a bit affraid to play with power. Wouldn't pluginn a HDD to a device the way i'm unsure of... would'nt it be dangerous for my wizard? i'm a bit worried, because i already lost one of these toys due to electricity... http://forum.xda-developers.com/showthread.php?t=281932

At the end of the last post, someone mentioned that all HTC devices has a 3.7v battery which would not able to generate a 5v required for any USB devices. This fact seems to be true enough, in a electrical point of view. Theoritically, it is possible to generate a higher DC voltage via a DC source, however, it would take up relatively large expensive real estate of the motherboard. So, unless HTC has a very good reason, requiring them to get a 5V from a 3.7V (eg for some fussy components), HTC shouldn't have any form of DC voltage doubler in the unit. So, consider the voltage wise, you are out of luck.

Yes that is true, but they are also saying that the processor of the wizard can act as an usb host. So maybe it should work with an external powersource, aka USB Power Injector.
...which leads us back to Zeno's drivers that require a USB power injector...
Has anyone figured out if its possible to use the ExtUSB (sync) port as a USB host port? I'm guessing the communication lines could be controlled with software, but that you would have to use an externally powered USB hub (or devices that are externally powered) unless the +/- charge lines are 2-way.

I don'ty know the answer, but... what for? The X7500 has the cable to allow USB devices connect to the USB host... so? And for sure you will need a cable to convert mini USB to female regular USB... so is not a matter of money or carring a cable I guess.
Mostly techie curiosity. I figured since someone already figured out how to reroute internet sharing to make a wifi host, someone else must have looked at that normal-looking usb port and thought about making it work like a usb host. I'm a programmer but I don't have time to work on that...

unfortunatly the chip that does that feature is not capable of that.
if you look at the schematics of a root hub it has 1 main chip that is the hub controller, and slave chips for each of the ports. a device interface has a diffrent type of chip that's intended to be connected to a root hub connection port. thusly no software fix could be made too convert a port intended to be a connection point into a root hub port
mind you the 4-in 1 cabloe is cheap enough and i saw at least 1 site via google that had a usb port only cable for the sepcial connector
so is worth looking at that.
Hey - do you have the details of the company selling this 'usb only' cable?
Thanks for the input. Just curious if it could be done, I hadn't tried to look up the schematics. I second the request for the info on the usb-only cable, that would be perfect since they already gave us a vga cable...
Would this "USB cable" allow me to use a 149GB externally HDD caddy like I managed on my Dell x51v Axim's CF to USB slot, as the 4 in 1 cable isn't cutting it?
Thankz
There are lots of posts related to external HD and X7500... in general most of them (99'99%) don't work properly. In the webpages from HTC said that the 4-in-1 cable only admit mouse, keyboard and pen-drives.
hi:
i think i will try to get hptp from ebay.
i see that it doesnt have usb for flash drive..
assuming that if connected to a dongle, it will read/write to flash drives,
which adapter should i search for.. mini male (for tp) > usb (flashdrive)?
thanx
I have read a thread on the usb host mode for the TP (can't remember which of the 8 forums I am on) that the micro usb port WILL support host mode BUT you will need a "Y" cable to provide power at the same time. Do a search for "host mode " on the TP forums and check it out. I have not attempted it so far as I have not found the correct "Y" cable mentioned in the thread.

There is fully functional USB Host support, you don't even need to do any SW modification, everything is supported out of the box with one caveat, you need external power.
Support for keyboard, mice, harddrives and cameras is fully built in the default WebOS software.
I guess HP planned to sell their own USB attachments, iPad-style.
The only thing you need is USB OTG cable. Like this: http://www.ebay.com/itm/New-micro-U...781644?pt=PDA_Accessories&hash=item19c7d49acc
Basically just search for "USB OTG cable" on ebay, costs about $3. And USB Y-cable. The only two things you need are OTG microUSB cable and USB Y cable to provide external power.
I am still looking into possibility of self-powered usb host mode, with all the support HP built in for it it almost sounds like a given there must be a way to enable it one way or another. Unfortunately chipset documentation is almost nonexistent.

the y cable search was confusing:: i do not know which kind to look for plus.. i dont see how to use this thing.. how does it get power.. i spose the USB OTG cable plugs into one of the "y" but im lost really...

What i've got: unusable pile of crap. The whole system can power up a mouse or gamepad, or external HDD (which is need to be powered from wall socket in addition to TP) but it's much worse with anything else: 16gb flash stick - lights up, but not enough power to read data, USB card reader don't even lights up. And situation with powering from PC USB (instead of ext. battery) is the same.
Anyway, even if the whole system would work, i doubt that you would take all those cables with you wherever you go, so it's useless.

As some of you know, I could get USB host to work on the release candidate of HoneyComb but not on the final release (3.55.405).
This morning I thought I would try again, my flyer was turned off (completely shut down) when I plugged in my portable hard drive (Seagate 120 gig using the Y cable one to a power supply the other to a USB micro USB adaptor).
I then booted up the Flyer … low and behold there it was. Shows up as USB in Astro but, does not show in Root Explorer.
I was able to watch my movies and play my music from the hard drive.
It seems like the flyer with latest HoneyComb will only see USB peripherals at boot time.
Great news!
If you care to try some other configurations, I'd love to get your results when using a usb keyboard or mouse?

It works perfectly fine without rebooting. The only thing is that you have to umnount before unplugging. It worked for me even with one 1TB Harddisc.

What Rom are you using? Most of us have been unable to get Usb host working on the latest HoneyComb release.
Edit: just tried again and won’t work for me unless I boot with it plugged in. Also, booting takes a longer than normal time.

I don´t use a custom rom I use the HC stock rom. You have to have the "/mnt/sdcard/usb/" folder. If you don´t have it, create it. I use only as I mentioned a 1 TB Harddisk and I used also two different kind of 8GB USB Flashdrives with a Y-Cable with external powersupply and a Nokia OTG Cable.
They work all perfectly fine. Only I had to unmount the devices before I unplugged otherwise I needed to reboot as well for a another usb device.
I didn´t try any other peripherals.
I am not a "tecfreak", just an average user who likes to tinker and mess around with his gadgets. If you have any further question I can help you with, Please ask.
P.S.: before I used the Nokia Cable, I used another Micro USB Male to USB A Female Cable and that didn´t work, so If it doesn´t work for you than it might be caused by the wrong cable. ????

Been doing some more testing … I noticed (when using the Y cable on my drive) that when I power up the hard drive the charging light on the Flyer comes on.
So, somehow power is back feeding to the OTG cable.
This leads me to believe that it may work better (like Elfuente stated) with a different cable.
Perhaps the Nokia cable does not have the charging pins
Ps: I noticed that on my Y cable … one is labeled Power+Data the other is labeled Power
I had a rather long message typed about this but the browser crashed, I'll possibly retype most of that later, but for now suffice to say that cables are singnificant in these setups.

Ahhh there you are I was hoping you would show up. If anyone could shed some light on this it would be you. Do I smell another hardware hack?
Keeping in mind my abilities in this field are very limited but, I was thinking … if I could come up with a battery pack for a portable hard drive I could (with the proper cables) then just plug it in and have the ability to read and write to it.
Maybe another hack for an adapter to provide power from a battery with usb connector or mains usb charger but it should actually be fairly trivial to implement, so maybe a schematic also for anyone who is remotely comfortable with soldering.
The big difference between OTG and other usb modes is that pin 5 is electrically significant. When grounded it indicates to an otg capable device that it should go to OTG-A mode (OTG equivalent of host mode), when floating it's ignored and the device will not detect a connected device.

That´s exactly what I do. I travel a lot and was used to carry a netbook with me. Now I changed to the Flyer and use the external 1TB Harddisc with a BatteryPack as external powersupply (http://www.amazon.de/gp/product/B003ZV1A1Y).
As I already mentioned: It works fine for me.

I’ll then take both apart (drive and battery) and mill up a case to mount both of them in.

I made a USB dongle that plugs into the USB port on the touchpad and provides a powered female USB-A port. It is basically a portable USB charger/battery with an OTG cable soldered to the USB port. Attached is a quick pdf showing the process. It's much smaller and more portable than using a y-cable and powered hub or battery pack.
The charger is $13 on Amazon with free prime shipping and OTG cables around $2 on ebay.
It's nice because it's small and I can secure it to the my case with a rubber band, providing a quick connection to a keyboard/mouse or usb flash drive. The particular charger charges via any powered USB port with a provided cable.
This is the battery pack I ordered, note the picture on the amazon page is not 100% accurate:

This hub has 4 ports, a battery plus solar charging. That said, if I buy it I'll probably just plug it directly into the OTG cable rather than solder them together. Then again my soldering can be a little rough.

Deserves sticky, love mods like this even if not always practical.
Cant believe they didnt give the touchpad a powered usb host. I guess they figured people would have issues with not enough power or drain the battery too quick with it.
So I think when I have some spare time I may mod your mod and show how to make a powered usb host that plugs into the wall charger so when your "docking" somewhere to charge you can hook up a keyboard and use it without restriction and even be charging the touchpad at the same time.
Probably don't even need to be too creative a proper Y cable may do the trick out the gate. Just to track one down.
Probably a stupid question, but it wouldn't be my first one...
Could you simply use a USB male-to-male cable to go between the battery pack and the OTG cable? Eliminate the soldering that way?
Or am I missing something?
I found a cable that I think will work perfectly for my idea of doing this from the charger instead of from battery: http://www.dealextreme.com/p/usb-fe...gb-tf-card-card-reader-kit-for-xtc-clip-82289
You can do it much cheaper with adapters and a regular y adapter though, and you may want to do so, so that you can have a longer cable from the charger to the y split, but yeah I will try this out sometime soon and let you know how it works.
The charger probably gives enough power to easily run things like a external HDD and such while the battery pack may not.
@Vicious ... couldn't that possibly put too much power to a USB device? Just saying since it is probably meant to be hooked up to a regular USB 5v port and (I don't know the specifics but) the touchpad USB power adapter has a high AMP output (might be talking sht here).
Nothing to worry about a device only "pulls" the amperage it needs so you can have extra with no harm to the device. It is the voltage that needs to match and usb is standard 5v.
Having too little amperage can actually cause a device harm due to malfunction, like a head crashing on a 2.5" hdd during use or a thumb drive failing to flash properly corrupting a sector.
I feel anybody that uses the touchpad in a docked setting that wants to use a keyboard may very well make use of my idea, that I of course got from the OP's idea.
I'll part it out for the cheapest way to make it without any cutting/soldering and test it soon enough.

That cable will work fine. I wasn't doing anything special, only eliminating the y-cable. I mainly wanted a small form factor way of adding a USB port to my case for portability. Now I can put a movie on a usb drive and watch it on the go.
You generally don't have to worry about using a supply that is to powerful. As long as the voltage output is 5 V, the device will only draw a certain current and consume the corresponding amount of power. The rating on a constant voltage supply is simply the maximum current it can provide, the amount it provides depends on the properties of the device.
Say you have a device, it states it operates at 5 V and draws 100 mA of current. That means the impedance of the device is R = V / I = 50 ohms. So if you use a 5 V supply rated to at least 100 mA, the device will only draw 100 mA. The supply can be rated for 100 mA or 1000 amps, it does not matter. (Although you wouldn't want to use 1000 A source as if something breaks or shorts it can draw a higher current)
Wikipedia "ohms law" if you are not familiar.
I tried to do this but can't get it to work, the touchpad shows the charging battery icon only it's not charging, and running dmesg it say source=charger mA=100 and usb otg exited low power mode and then right after says it entered low power mode... Not sure what the issue is...

You may have the two data pins shorted together. To the best of my knowledge, this tells the touchpad to go into charging mode. The touchpad charger does this, because in order to charge, it must draw more power than USB ports are designed to provide.
You need to remove the two resistors circled in the PDF. These keep the data pins shorted together as well.
This is a really great idea I think I might try it and your tut is very well explained thanks for taking the time out to put it all together
Thanks
Mouse works fine, keyboard hasn't been tried yet. How do you access a flash drive through this? What are the steps?
If you just cut out the resistors in the battery hub, could you just use the TP's regular cable to plug into one of the ports on the hub?
