I guess most of us faced the too much power problem with OTG cable while connecting to certain devices like usb modem or 6 axis (PlayStation 3) gamepad
I was thinking what if I used external power supply using a hub as shown in the attached pic
would it work , is there any other solution?
the pic is a method for usb otg non supporting devices like nexus s, offcorse they also need a special kernel and certain apps
sorry I'm new and can't post links
any comment is appreciated
thnks

in order to solve that problem, you must connect a powered usb hub to the phone, and the gamepad to the hub.

No, it doesn't act as a host. I tried to read a USB 4GB memory stick without sucess

Hi all,
See my thread here post 2 has USB Host drivers, however they are untested on Rhodium so far.

What cable are you using to test USB Drive with TP2? I was hoping for the same sort of USB cable as the athena allowing you to plug usb devices into TP2 and use the TP2 as a host.
Thanks, Andy

Hi,
Can anyone tell me if there should be any technical reason why the Flyer cant run on Honeycombe 3.1 and implement the usb host update so I can download jpegs from my dslr using usb.
Many thanks.
It might be worth trying it without honeycomb, I believe that Qualcomm chips have supported USB host since Eclair, perhaps HTC enabled it already?
Has anyone tried it yet?
I'd like to read some gps data from a SD card.
Thanks guys but needed a tablet asap which would also allow me to transfer files from my dslr via usb. Its been confirmed on other forums that the 3.1 update from Motorola will enable this so went with the Zoom
If you just need it for the DSLR have you considered an EyeFI card? For less than $100 you can get a direct connection from the camera to the tablet (or phone).

I know, its a great solution but my D700 only uses CF cards which aren't currently supported.

Yeah I have a D70 that's not supported either. I haven't gone and gotten one for my D60 yet although I've considered it a few times.
USB-host on Flyer
hi guys!
any news on this topic?
as there is already tmp root achieved and permanent root on s-off flyers, has anybody already tried to implement usb host functionality now?
I believe to have heard, that Honeycomb should support USB-host functionality automatically... Do we need to wait for 3.2, or could we get it earlier?
I'd really appreciate this (as I am also owning a DSLR from Canon), and would be willing to donate.
greets, alf.
Sure that the Flyer has the necessary chipset to work as a USB host?

I'm actually working on a direct DSLR app using USB host, a preview of which should hopefully be released by the end of the week (alpha, not beta).
I'm mentioning this because it works on the Galaxy S2 with 2.3.4. I've not been able to get it to work on the Galaxy S1 with 2.3.4, but it just goes to show, it may not be 100% necessary to be running HC 3.1 to support it (as evidenced by the SGS2).
What kind of connection cable does the HTC Flyer have ? Micro USB ? If so, I'd advise to give the test app a spin when I release it if you happen to have a USB host cable.
Either way, the chips themselves have supported it for years and years, that's not the issue. Kernel and framework support and such is the problem.

yes, the flyer got a micro usb port.
I also happen to have the correct usb host cable (micro usb to usb-female...), so as soon as your software is out, I would give it a try.
please keep us informed, thx!

Test with a card reader or ext hd (powered) plugged to your cable and see if you get a new drive through a file explorer... The kernel will definitely need to support this functionality, or the fstab may need to be modified.

Indeed if you have a micro usb cable already, connect a usb stick, see if anything happens... that should tell you straight up.
of course I already tried different devices (USB-stick, hard drive, camera directly...), but there was absolutely no reaction ...
simply plugging it in doesn't work.

Then it's probably lacking kernel and/or framework support.
is there a way to fix this with root?
any news on this matter?

Hi Chainfire,
have you looked into the Archos Gen8 range of tablets for any kernel info?
They utilise Froyo and have had USB host since day one. Maybe you could patch something from there?
H.
And what about porting the results for the SGT described here? http://www.xda-developers.com/andro...e-versatile-thanks-to-usb-host-functionality/
I can't wait. A Flyer with notes, the pen and USB host would be an fantastic tool for photography AND for any kind of fieldwork.
If you can take a photo with a proper camera and then check it on a flyer awesome display and use the pen... just imagine!
Sometimes I'm afraid that HTC did not bet enough hard for a fantastic device!

Did it work before you flashed angelrom?
i didnt try it before my friend....today i bought the converter from micro usb to usb......so...is there any service that maybe did not is enable in the custom rom....and cant run the usb host....
It's unlikely that it's the ROM, as this is a feature that many people use.
It may be that what you are trying to use simply doesn't work. Do you have a USB mouse you could try? Also, is the device that you are connecting powered, or does it expect power from the USB connection?
well...i connect 3 devices... a keyboard...a mouse...and a usb strage stick....
and no led...power on...of the devices
In that case, I suggest you ask on the thread where you got the ROM. Have you already searched that thread to see if anyone else has the same problem?
i did a quick search...but i didnt find anything important...well ok my friend thx....

don't bother checking with more devices or posting in the rom thread, you just bought the wrong cable for otg purposes.
a simple converter from micro usb to usb won't do, the sgs2 discovers connected devices by the resistor between pin 4 and 5 of the micro usb plug inserted, and afaik, a usb otg cable needs a 200k resistor (if you decide to weld one in yourself, double check the number against other threads, i am not sure about that). simple converters, adapters and even some "usb otg" marked cables don't have a resistor in there.
and if the correct resistor is present in the plug, the device should discover the cable when plugged in, and then you can connect any device afterwards and get another notification. (as is seen in the usb otg video in the accessories section.)
i hope you did not pay too much on that cable, or have the possibility to return it for a refund or exchange, because yours has little to no known uses.
Thanks Chef, I didn't know that. That's the "something new" that I learnt today
thx my friend..i give 4 euro for this ****...but its ok....

Anyone got a USB mouse to work on their G9?

I dont want it bad enough to buy an adapter '
edit 2: someone said probably need a usb hub to translate usb 1.1/2.0
I can't get it to work through the back USB port either. Archos themselves say you need a micro USB to USB host cable, I ordered one today so I can test later.
Don't worry. Spend a dollar and buy OTG USB adpter. And your device will looks sexy not inside but and outside.

The 3G USB host port needs definitely a hub to handle USB1.1 devices.
The OTG USB port is able to work with either with USB1.1 and USB2.0, but is restricted to work with HID and mass storage devices, due to software restriction.
AFAIK there's no general device support on the OTG port.
Correct me if i'm wrong...
