Does anyone think is possible to use
a second Sim-card over USB?
(I know there is stuff like dual-sim-adapter.com )
If you find/write a host driver that would enable VBUS output, USB SIM card reader, write a driver for this USB SIM card reader and integrate it into closed-source (as in "not available to general public") radio build - yes, it will be possible.
Until then - I guess not.

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
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 ??
reo
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.
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.
Hi,
Is there any way to read a memory card from the TD's mini USB port. I have a small device that has a mini USB on one end and a USB on the other, inside this there is a micro sd card (I have pulled this out slightly, to show where it is). I can charge my TD with this device and I can see the memory card via normas USB but can't access the memory card from my TD, any ideas??
Thanks
The diamond does not have any USB host drivers, except in the bootloader, so it won't work.
Since this device lacks the microsd expansion slot, I was thinking to add it internally. I don't know yet if it's possible, but my idea is to add it in the sim card empty slot.
Do you have any clue about it?
Let's open a "project"?
Here is the mainboard of the 7310.
The idea is either we find another part of the mobo like the one ready for the simcard, hopefully ready also for a memory card holder, or we connect a generic sd holder to the usb pin of the main connector of the tablet.
Here is another piece of information... http://forum.xda-developers.com/showthread.php?t=1118986
Thanks, very useful.
Well it should be feasible, it's enough to connect the usb pin, but there are some questions to be answered.
1) If a memory card is inserted will a device connected to the 30pin connector work? Or does work only 1 device per time?
2) Will this kind of connection work like a normal microsd holder connected to the mobo by default microconnector? I mean, will it use more power, will it drain battery faster because voltages etc..?
3) will it be useful due to the possibility to install apps?
It's important to have answers to these questions, but the operation is very feasibile.
Well, I'm thinking that this mod using the usb pin doesn't worth the trouble.
Usb needs 5.0v and it's too much. Using 5.0 continously drain a lot the battery.
Instead a stock 3.3v powered microsd, is far lower battery hungry.
The problem is to find on the mobo the pinout (if present) to connect a microsd holder.
Gt-P7500 is ready for this connector, but as far I saw on pics of 7300's mobo there's nothing similar.
It would be interesting to read the service manual of 7300 just to understand if the chip and the mobo are predisposed for such a connection although not present.
Internet is full of 7500 service manual... but something for 7300??
I've found this generic adapter, ready to be connected on the equivalent pins on the mobo. The problem is to find the schematics of 7300, just to understand where and if are the sd control pin on the chips (but I guess so).
