Send a signal through mini-sub

EDIT: Oh damn, I meant mini-USB not sub xD
Hi!
I'm new to this forum, but I'm not new to Windows mobile. I have a Canon 40D and I don't want to spend $300 for a remote controller so I want to make one myself. Now I found how to close a shutter on my canon 40D with a serial port:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
(Full article: http://www.covingtoninnovations.com/dslr/CanonRelease40D.html)
But now the problem is: I don't have a serial port on my HTC Tytn. Now I have 2 choises:
One: I've found that mini-USB cannot send a RTS signal. I've found then a miniUSB to serial adapter: http://www.usbgear.com/computer_cab...&cats=199&catid=482,1303,199,461,106,1009,601
But can I connect that adapter to my HTC and send a signal to usb so the serial port can send out a RTS signal? Or do you need some specials drivers for that? I can program with C# but i'm not a pro so I can't program any drivers for my HTC
Two: Can I make the mini-USB port, on my HTC, trigger a relay? (I've also found this: http://www.soft82.com/download/mobile/relay-timer-ppc/ but you'll need a relay board for this that costs $120 and like I said i don't want to spend that money.)
Thx for help, but if you don't know how to manage that, it's no problem.
PS: sry for my english

Using USB Female to Female for USB HOST

Hi,
i was thinking how i can fix a cabel for USB host for the HD2
i came to this idea: a USB Female To Female adapter,
what will happen if you connect your data cable to 1 side, and a USB Stick in the other side? will it work?
here's a pic:

Doesn't work mate. The HD2 does not work as a USB host.

then i thing you should see this post: http://forum.xda-developers.com/showthread.php?t=638201
and see your Register on your HD2..
OR google it,

Hey Mitchell,
Unfortunately this would not work directly since the HD2 does not power the external devices currently, you would need to create a modified wire that connects the power lines from the external usb device to some other power source (maybe a pc usb socket)
but this connector could be useful in allowing you to create this wire without having to hack up a hd2 usb cable itself.

As above .

There is also the problem I didn't mention that Cotulla never released the driver for this and since Cotulla has not been around for a while now it seems that this project is suspended indefinitely.

Anyone got pics there usb charging cable?

Just bought a "brand new" HTC HD2 online and I am questioning if the usb cable is the original one. The end that plugs into the phone is really hard to shove in and fitment just doesn't look right to me. I need something to identify if I have the right one and not being scammed. On the end that goes into the phone there is an "Arrow" image and other side no arrow but oddly the only way it fits, is the arrow facing downwards.
Hope someone can help me out. TIA
PS: This is a USA T-Mobile one if that matters

Some plugs fit more snugly than others. Does the phone charge with this plug? If yes, then it is the right plug. I havn't personally tested it that it would even fit, but if the micro side of the plug is a rectangle then it's possibly a Micro-ab USB cable (but I doubt it).
Here's a pic:

Your plug should look like the Micro-B with slighly sloped edges on one side.
Micro usb like all other variants of usb, are not usually close enough in size/shape to fit any other adapter.

Problem with 3.1 Ice Cream

Will we be unable to do HDMI out and use a controller since they use the same ports?

HDMI out is MHL; controllers are USB OTG. I believe it's a hardware limitation that the two can't be used together, unfortunately. But nothing stopping you from using a wireless one (if there's one that works).

Yes that's what I meant with this only apply to GSII. I guess only a bluetooth controller would work though.

I think that the MHL-adapter will have an micro-USB port on it. It looks like it will on these pictures as well:

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
But I don't really have any reliable source to that.

The Micro USB port on the side of the adapter lets you charge your phone while in use.

BT Keyboard Case MOD - OTG - USB HUB

Hello people!
I own a Samsung Galaxy S2 (I9100) and I've been fantasizing with a very particular MOD.
I've seen this Blutooth Sliding Keyboard cases:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
But I would like to get it working thorugh OTG, and take advantage of the extra height o add a USB port for USB DRIVES using an integrated USB hub.
This way I wouldnt need to carry around an OTG cable, and wouldnt have the constant drain beause of the BT pairing.
My main roadblock at this time is wether I could get the keyboard working through USB (bypass the bluetooth interface) so it could get recognized by the phone.
Once I can sort this out, the rest of the mod should be quite straightforward.
I dont own the keyboard case yet, so If anyone has some previous modding experience could shed some light on the bluetooth matter, it would be of tremendous help!
Thanks a lot in advance.

I don't have the first idea how to do this but I am very interested!
I like a physical keyboard and I've had to import from the US or stick with very outdated phones....
