Hi
I wanted to find out if it is possible to adjust the drivers or to just create drivers of an external device to work on a pocket PC ?
Since the communications port on a Wizard is already a mini USB can a regular xp driver be adjusted so that when you plug for example an external HDD and obviously use the appropriate mini usb to mini usb cable into a Pocket pc that it would detect and install onto the device so that you can use it in the similar manner that you would on a regular XP based system ??

there is no USB host drivers, nor is the mini-B port capable of putting out 5volts.. not possible to do what you are asking of the mini-b
Hi
considering that the power issue is not a problem and that the devic has external battery power, would it be possible then ?
OR
Do you think that there is a way to adpat the device to work as a SDIO, so basically convert from USB to SDIO ?
reo
I am not an expert, but I have read somewhere that there are two kinds of USB chip sets - one that is slave-only, and another that can act as master (also called "host mode"). Devices, such as phones, hard drives, flash drives etc., have the "slave mode" chip, and hence cannot be used to act as a host, which is what you want to do.
I am sure someone will correct me if I am wrong!
i researched a bit on USB and SDIO, and it seems that SDIO would be a way to add an external device...
Now would it be possible to create an SDIO device with a host USBB controller in it ? or do i have this all mixed up ?
reo
Yes, that is possible, in theory. However, the SDIO spec does not support Mini-SD afaik; or, even if it does, I have not seen any device maker that makes a mini-SD device (other than the usual flash card). So, I think you are out of luck on that as well.

hello im working on a htc wallaby usb interface. but i have stumbeld across the problem that the htc wallaby is only a slave interface and therefore cannot use usb devices as they are also slave. how can i make the xda a host device? thankyou.
Raptor,
Read MSDN USB site about USB and the need for a Host Controller in order to host USB peripherals. They recognize that wince/pocketpc should have hosting functionality but they haven't got there yet, therefore all wince devices have to be treated as peripherals for now, which means for now you can only run as slave. If you need to drive a usb peripheral from your wince device an option is to add an SDIO pcmcia USB connector and write USB drivers through it. A forum on ExpertsExchange talks about these add-ons. I can;t imagine this is the solution you're looking for though.

hi i was wondering if anyone out there new if there was an SDIO USB HOST card, similar to the shown on the link below (but obviously SD not CF)
http://www.ratocsystems.com/english/products/subpages/cfu1u.html
if not, does anyone know/have tried the above CF to USB Host with a standard usb webcam and got it to work? if so can you explain how i go about setting it up.
thanks

i'd suspect that the fact that usb to host have to supply 5volt with 0.5mA
it could be an issue for something as thin as an sdcard
also not sure if the sdio interface even operate at 5v
usb host
I haven't seen an sdio to usb card, but I use my "htc universal" with it's mini usb as a usb 1.1 host. It works ok but you have to supply external power.
if you have that working you are the first and only person i know of who gotten any htc device act as usb host
sure there were rumors that it would do host
but later on ppl retracted those claims
After wiring up a cable for that, how do you set the phone to 'host mode'?
Thanks
usb host is not a mode
your pc is in host mode always
as are the 2 htc devices which do support
usb host out of the box
is a device is connected and the driver
is present the device works
Nope, USB host is a mode. It's the whole Master / Slave affair. Granted, it's automatic for most devices when another is connected... ah... that ought to answer my question I guess.
Hi guys,
When I connect a card reader/USB flash memory to the USB-port on the connected 4-in-1 cable, how to access these memories?
I also have an external hard disk, which has its own power supply (so no "too less power" issue), but the Athena doesn't do anything with it.
Do these attached memories need to appear as Storage drives in the file explorer?
Thanks.
I received my 4in1 cable yesterday and I found that it recognize hard drive randomly. I mean that not all USB memory are accepted by system. First of all it accepts only low voltage ones and not all are recognized. About mouse host...it recognize mouse but it's unable to show pointer, even with some drivers found on the this forum that should enable it...
So I would like to know what kind of commercial policy is this??? HTC says that with this cable and device you can host HD, mouse...but it's all pretentious, because to use it properly it's really hard!!!
I'm quite disappointed!
Again: when an USB storage device is connected, assuming it's a low voltage device, WHERE to access the memory??
It's an old thread, but what the hell. Plug your USB memory into your 4 in 1 cable. Use file explorer, go to "My Device" where you will see MicroDrive listed. Further down you will see "Hard Disk". That's it.
Thank you, this solves my problem.

mouse pointer works fine with me. Are you using wm6?
I don't think it's just a voltage issue with USB host on the x7500 - I just don't think it can cope with reading from large storage devices. Mine reads 1 gb and 2gb sticks fine. It also reads my 4gb and 8gb sticks but I experience drop-outs and slowdowns with the higher capacity sticks.
I should imagine that a 200gb HDD would send the x7500 loopy. Besides which I don't see the point in having a pocket pc with a mains connected hard drive wired to it. Might as well use a laptop as that would be more portable.
Has anyone tried to connect a (SD) cardreader directly to the USB port of the Diamond ? Is this supposed to work in order to make backups for instance when there is no PC available ?
Another thing I noticed: when you click on Settings -> About it says: "Expansion slot: not in use " !
Is the expansion slot hidden somewhere ? ;-)
Nobody has to try because you're not working with xp or vista. Already think about the os size between a pda system and a computer? A windows based computer has the most fortcoming drivers included in the os. So you need drivers, a mini usb adapter and the usb connector needs the possibillity to communicate with the cardreader.
And the expansion slot, think about the universal os wm 6.1
Hi, for HTC Athena there is an adaper for USB2.0
I connected a 4GB USB-Stick and it is shown in Fileexplorer (like SD-Card) on device.
It is possible with WM6!
Hopefully there will be a such an adapter for Diamond too.
Theres no USB-Host function, so can't be done.

Rorydarekign: Could you confirm the source of such information.
I really hope to have USB host with Diamond and I think there's chance that it does have it. Hold Vol Down and Back while softreset shows "Trigger USB host". I am not sure what it means but just want to let you guys know such undocumented feature.
It doesn't come with USB host support, so no hope for external HDD or card readers.

The chipset does support USB host, however the feature is not activated in the Diamond. Could someone give it a try, all you need is the normal Mini-USB cable with a gender adaptor to connect it to USB Stick. Try the undocumented feature described above.

I won't believe that post as an official one. Until someone tries it out I'll hope. It could solve iGO8 problem as well.
Usb port is it locked or there is possibility to use it like usb host ?
To manage copy pictures of a camera to phone without pc by usb adaptator.
Samsung talked about usb 2 hdmi cable and think if its real it use some usb video card supported by phone(because of physic material imcompatibily of hdmi nd usb)
May there is a way to dev a tool or hack to get it works...
Aah!! Finally somebody like minded!!
I had been scouring forums for something like this. USB OTG would be an excellent add on to this phone. If not OTG, at least host would be an excellent idea.
No idea whether the existing USB Host driver for Nexus one would work on this one.
The processor on SGS already supports USB Host (not sure about OTG though). This has been pointed out in their press release - w w w .samsung.com/global/business/semiconductor/newsView.do?news_id=1043
I am just wondering - should we request Samsung themselves via mass petition to open up this feature on SGS?
some USB devices might be compatible, like the 100/1000 Mbps USB to RJ45 plugs
those same ones works in Windows Mobile it should work as well for Android, however a driver will be required.
mouse and keyboard support should work out of the box
external USB keys for storage, or even USB mass storage devices should work out of the box as well.
usb audio... hmm... not sure what else at the moment
Hi AllGamer
Thanks for the reply. So how exactly do we get this going on SGS?
I am much more interested in having USB HDD support on SGS (hopefully without an ext power source - am I asking for too much? ).
Are you suggesting that the N1 fix should work here also? Can somebody help us with a "How To" to enable this on SGS?
Cheers!!
Coooolboyz
you can plug in any USB mass storage devices (USB hard drives) and it should work.
However, you might not get enough power from the usb port, you'll still need need power cord for your external usb hard drive.
I know on my HTC windows phones works like that, it should be the same for Android.
I'll try that when i get a chance.
you just a need a USB female to a mini USB male cable
yep!! you are right about power!!! I am trying to get a cable - hopefully in couple of weeks should have this.
but I am wondering if all this would work without proper drivers in it. Would SGS have USB HDD drivers in it already?

I can see one problem, You will only be able to use Fat32 drives unless someone compiles NTFS / HFS+ into the kernel. Ext3/4 is already done so I don't see many problems. What I recommend you do is get some sort of adaptor for Female USB > Micro USB and test it out with a flash stick or you can hack one .
Yeah - I understand the difficulties of having NTFS support outside the MS world.
I didnt know that ext3/4 were already a part of the kernel!! Is this by default available in all Android kernels?
For USB Host cable - I am guessing that this one can be used - http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=250671106072 (same as what Sven used for N1 USB Host capabilities).
But I seriously doubt plug and play would work (that would be too much of an expectation! )
Does any body have that cable here, who can check out if SGS does actually work in USB Host/OTG mode?
Sven has try with a Galaxy another Host Driver
h t t p : / / sven.killig.de/android/Galaxy/
Hm what can we do with these files?
However, any news about this?
Maybe, we could ask some Galaxy S kernel developers about this.
