USB Host Capabilites

I read that engadget was able to get USB hosting working on the universal, however it appears that this is not possible (reading the threads here). I just wanted to confirm that using a 'usb dongle' to connect other devices to the universal does not work - as I thought that wm5 did support this. Is it just a question of drivers or is the hardward not capable?

Just to remind that topic...
I'm really interested is it possible to connect a portable harddrive to my MDA Pro?

i dun think so its true. If anybody proves this to be true, then please let us know.

noname_nick: have you found the engadget article?

@Vijay555,
It was a Q&A article they posted when they had just received the Universal. Should be there in their archives i guess.
Cheers.

I just checked with an sd card reader and a 40gig usb hdd....it didn't detect either :-(
don't think the universal supports usb hosting :-(
hope its just a software handicap and not a hardware one!

yeah I even posted in that engadget article asking to reconfirm their findings and thry did reply saying it could be used as a usb host as they had it dine themseves (it was one of the factors that made me get the universal) alas the dumbfuc*ers removed the ABILITY for usb host or maybe engadget was Forced to say yes(as in LIED) under pressure from htc etc??
just my 2 cents !

If I'm not mistaken, the hardware in the Universal supports USB Host. But it is not implemented in the software running on the Universal... It's like having a sound-card in your computer, but with no drivers to use it. Maybe there will be a patch or update for WM5 which supports USB Host.

Suspect that you need a USB host cable to have any chance of testing USB host functionality, this cable tells the PDA that it now needs to work in host mode.
The Sharp Zaurus has a similar arrangement where a single USB port can work in host or slave mode, which is switched using the relevant cable, link to such a cable http://www.streamlinecpus.com/store/product.php?productid=100&cat=0&page=1&featured
Suggest you search Zaurus forum (www.oesf.org) for more information.

does anyone has this cable and test it already?
It seems it will fit the mini USB port for the Universal?

Don't think it's native on the Universal - if it was, it ain't now. In the meantime, Softick Card Export II PC version 2.10 works great as USB Host services to the Storage Card!

Yes, I use the same thing on my Uni. I like it very much as i do not need a SD card reader anymore. But I still dream to be able to hook up my external slim HDD to my Uni.

Here is the article http://www.engadget.com/2005/09/02/...l-questions-weve-got-htc-universal/1#comments

I found driver for Toshiba E740 USB mass storage driver ( for PPC 2002) but maybe is a best way to find solution for Universal - it's look that only soft for this funcionality is missing :?: Deje PocketPC Page

usb host.....
USB standard provide 5 volt DC.
All HTC device have got 3,7v DC battery!! so it is not possible to power any kind of USB device!!.
The only way consist in voltage duplicator that should provide 5v using 3,7 v source, i think that HTC device has not this voltage regulator.

the universal have the hw to have usb host functions but htc don't have put it to the out side world.
The mini-usb can't be used as initiator.
in thoery you could open the universal and hook another miniusb connector on the usb bus.... and then the drivers nightmare
Deje have drivers for mass-storage on ppc2003/ppc2 and they work fine.
I use both on casio-e200 and on the toshibare800.
btw:neither casio nor toshiba have 5v bateries and they work with external usb devices like keyboards mices etc, for disks i have to use external power...

USB Host disconnected pin?

hello,
i've heard that the universal WOULD support USB host drivers if an unconnected pin inside the universal was connected... could anyone tell me;
- if i manage to get the pin connected, would i get usb host features like on any other usb host phone with proper drivers?
- how hard is it to do?
- WHAT to do?

Oh man,really really nice interesting idea,hope it's true and possible,i hope someone knows all about that and soon writes here how that is possible maaan,would be really awesome to play with that

nice to hear someone else would like to get it to work too
EDIT: just found this on another thread on another forum about a PXA270 phone, someone was trying to get it to work, seems like all we need is
- switch the pin to host mode
- a driver (maybe zenos latest ones?)
After about 6 months of not touching this project, I decided to take another quickie look at the PXA270 docs and programmers reference. What I now see is very interesting.
Originally, I was looking at bringing out the USB Host 1 interface pins to the outside world as they were only terminated internally on the motherboard. Only about 1% of users might be able to do that.
I then started to look at the USB OTG (On The Go) interface that this chip supports. The USB OTG interface can be used as both a client and host. It shares the same pins as the Axim's serial port. Unfortuately, there are two serial control lines pins that are not brought out to the connector, so I scrubbed that idea.
This past weekend I picked up the programmer's design reference book to look at how the various USB interfaces are programmed and I saw something that I missed before as this was in the USB Client section. It appears (to me anyways) that the USB Client pins can also be programmed to act as a USB Host when in the USB OTG low power operation mode. The manual discusses how the additional control registers are used along with an output mux and charge-pump circuit (to provide the +5v). Refer to the PXA27x Processor Family Developer's Manual - dated Jan 2006, sections 12.5.2 and 20.
I will be looking at this more closely to see if a simple driver can be written (Afarre, where are you...) to switch the USB client pins into Host mode. In addition to this, the USB device drivers would be needed. Please remember, an additional IO interface circuit will be needed to connect between any USB device and the Axim as the proper voltages are not on the sync connector.

haha same, btw thats the link to the topic:
http://www.mobilitysite.com/boards/x50-x51-forums/140071-hacking-pxa270-internal-usb-host-24.html
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).

seems like they were still working on the driver (which we already have(?)) so we only need the hardware mod.... i guess...

Ummm it's definately a crazy idea. We were discussing with mamaich (our guru) last year. Unfortunately it's not that simple to provide the power in sync connector, which is acting as a usb client (connector) at the moment.

did you read in the thread i posted a link to? they had the same problem, but also found out that it maybe is possible to provide the nessecary +5v too, they were not sure tho, and i thought maybe zenos drivers contain the code to do that.

Ok, seems there is a new idea of power injection from outside.
Anybody tried it...?

Couple of months ago, I was trying with outside +5v power but nothing happens

did you use one of those special USB cables that have two female USB-A, one for power and the other for the device to plug in?

http://htc-tytn-ii.handster.com/software.php?id=3339&for=HTC+TyTN+II
i don't know anything about this.. i'm actually looking to hook up something that normally has a rs-232 port.. but is also made in usb.. It draws power from another source
with something like that program doesn't that suggest usb host is possible..

http://gnalpgnarf.handster.com/software.php?id=3339&for=gnalpgnarf

hmmm....am I right or am I wrong?
Theoretically speaking the idea with a pin is supposed to redirect power from intake to output, however, not only Uni is incapable of supporting the output (you are essentially attempting to piggyback another device), the external support will not be possible due to pin configuration, regardless of the cable used.
Another thing, other than sheer experimentation, what would be the real point of such USB host?
STOP TORTURING YOUR UNIs, GUYS!!!!

I am pretty sure, that the Universal doesn't support USB Host.
It did not, it does not, it will not.
Sorry guys!
To be honest:
Yes, the PXA270 chip supports USB Host, but in most HTC devices they use this feature already for something else, like: WLAN or 3G connection.
DOMy

seen this?:
http://hhtinker.blogspot.com/2008/10/usb-host-on-treo-650.html

do you know what USB Host already busy?
it used as data call transfer radio <-> CE.
USB hub will not solve this problem easy.
also if you want attach it to miniUSB connector, you need additional OTG chip.
=> Host on universal is very hard to do, ...impossible.

USB capability

Hey guys,
I want to know what is possible with our USB-Connector.
What does it support/not support? (Host-Controller, driver...)
How is it build up? (beside the specs in the Wiki)
I'm happy with all helpful answers!

usb
It's a mini ext USB and dispite the bumff from HTC will work with any ext mini USB device.
My friends got a USB charger for his car , this works fab in our phones.. have a look in teh interweb , as long as it's gto our connecter it will work .. ( however there are some issues with poliarity as some of the pins are set up diffrently ..

I searched the internet about this topic (because forum search seems to be a bit crappy )
So I found a thread about USB-Host in Touch HD.
Now my question:
Is there a possibility to use the Touch HD as USB-Host device or is our Touch HD just a pure Client?
I thought about a mouse or external Harddisk. But if there is no Host-Controller, it's impossible
PS: I just found some thread about this topic (search funtion is weird finds "usb host" but nothing with "usb")
So from what I see, there is no host capability with our Touch HD?
Nobody tried Zeno driver?

There is an old 3D about HD USBHost: you could search.
HD has Host capability by chip but extUSB lacks of output power: serch 3D to confirm that
D'rath

Many thanks D'rath, that mainly what i want to hear
I think it's possible to bypass the lack of power by an Y-Cable or something like that. If not, i'm going to solder it together
Lets hope it works

I tried it
But I got bad news so far
Just soldered a USB cable together, so power supply is provided and I installed Zeno USB Host Drivers to get mouse support.
But it didn't worked
Just got the popup with "New USB Mouse" but nothing more.
Maybe there is some hope, that it will work, but I didn't get it to work.

Did you try using a flashdrive and see if it gets recognized ? I'll be interested in that.

I have just flashed a new ROM and I'm experimenting a bit.
But i try to test it in the next days, if I find the time
By the way, my car is rusting and i got little time because I gotta repair all the **** >.<

[Q] Which component do I need to replace mini-USB port

Hi there!
I'm trying to replace the mini-USB charger port in my hd2 but havent had the chance to open the phone yet and trying to buy components. which part do I need for it? a 5-pin or 8-pin?
I am currently awaiting for my torx screw drivers to come through the post and preparing all the parts I need. So far, I have not found any site that has showed how to fix this on the HD2.
My plan is to purchase the mini-USB port, open my phone up and solder in the new port. Has anyone attempted this yet successfully?

I also posted a response to this in the "Arrow
[FAQ] Q&A: How? Where? what? Ideas? [New Users?]" thread you posted this in. The HD2 has a 5 pin micro USB port, it is soldered to the bottom of the main board. I have read post of people having success with replacing it and I have also read post saying it is not just a easy task unless you are good at soldering. Good luck.

thanks! (my apologies for double posting). from what i've read so far on people trying to replace these parts on the internet, it's a lot easier if you used a dremel to cut off the rear shielding of some sort.
i think my screen needs replacing along the way but i wanna get the charging port working first
off to order some parts off ebay now

In hackaday there's an article on replacing usb ports.. I cant post it but I can send it over by PM if you want
By the way, do you mind posting some photos of the HTC HD2' usb port when you open it? I never opened mine but I need to change the usb port too.. so any intel I can get in advance.. the better ;-)

GPD XD OTG Issues

Hello everyone, I hope this is the right section where to post, I have scrolled down the home page until I've found this one. This is an android console based on Rockchip cpu so I guessed I'd give it a try with my problem. If not please forgive my dumbness and move the thread.
I have bought a GPD XD console that works very flawlessly beside one big huge damn problem I am not able to resolve.
One day I tried to hook it to my TV and looks great. Then I wanted to connect my 360 wired controller via USB otg. No luck. Then I tried ps3. Same. Ps4 controller? Again nothing appears on screen. Mouse, keyboards, flash drives, just nothing. Also updated it to last firmware. Tried 3 usb otg cables, 2 cheap one and one with gold plated connectors that costs more (dunno if this changes).
So I tried some of the methods I've found online to test the otg support and actually otg support is ok. What wasn't ok therefore, is that I had to download 3 xml files and putting then into permissions folder and allow them but still nothing happens. Downloaded then a vold file to put it into etc folder and again nothing works. The apps i've tried all tells me the otg support is ok but find me no otg signal
Actually usb port works for charging the device or make it visible to pc but this damn otg won't work.
I tried almost anything, . I am kinda noob at this but if usb works for charging and pc I can assume is a software issue and not an hardware one, or is it possibile the otg function depends on usb port "broken" even if usb port works for other operations?
Please I would be very glad if you could help me. Since it's passed too much time for a refund and send it back in China for a replacement will costs me a lot and takes like months if not one year as I've read around.
