Tutorial: How to get USBOTG to work with US iriver H3xx

[sirroot]

I started a new thread because the other thread was over used and would probably confuse someone who didnt know what they were doing.
Thanks to cyberguest for hosting the pics and Skeil for all this technical guidance. Also thanks to Reggie we have better pics of what the cable is suppose to look like.

I modified the tutorial and made it a bit easier....Im not sure if its going to work because its a little differnt then what i have. If it doesnt work let me know and ill add the extra steps so its similar to mine. Dont worry if it doest work...it can be correct easily...

Some notes:
1. Im an amatuer when it comes to electronics.
2. This tutorial is meant for people who dont have much knowledge about electronics.
3. You will most likely not messup anything by following this tutorial. The mod is pretty safe and non invasive...but....
4. You are responsible for anything you do to your device.
-------Start-----------
This is the overall plan...if you can understand this then the rest of it will be alot easier to understand.



Note the pictures i have will be differnt then your actual results because my cable is slightly differnt than the one that will be made with this tutorial(IGNORE THE small Black wire connections)...If someone actually used this tutorial and has pics of thier cable please send them to me or cyberguest.

Things you need.
1. Iriver H3xx with korean 1.25x firmware(learn to flash the US version in other threads)
2. Iriver host cable
https://secure7.nexternal.com/shared...RowID=104&All=
3. Cyberpower Battery powere USB hub
http://www.bestbuy.com/site/olspage....1&type=product
4. wire strippers
5. electric tape
6. scissors
7. knife
8. Any usb device that you want to connect to your iriver.(Im using a sandisk 12 in 1 http://www.bestbuy.com/site/olspage....roduct....most flash drives work too)
9. a glue gun..costs like 5 dollars at home depot
10. 1 wire..Im sure you have some at home. You can rip open a telephone cable(which most people have plenty to spare) or you can get some from radio shack. http://www.radioshack.com/product.as...%5Fid=278-1221


Step 1.
Charge the cyberpower usb . It charges when you hook it up to a computer. Takes 6 housrs i believe.

AFTER YOU MOD THE EXTENTSION CABLE DO NOT USE IT TO CHARGE THE HUB!..You can charge it by PLUG IT IN DIRECTLY w/o extension cable or use a normal extention cable..ALSO KEEP THE MODDED CABLE UNPLUGGED WHEN YOUR NOT USING

Step 2.
Strip the usb extension cable(the silver/clear one) that came with the Cyber power. DO NOT CUT IT IN HALF or THIRDS! You want to remove the outercovering..Unwra p all the protective aluminum and silver wires....they are just thier for insulation. You should see 4 wires inside...DO CUT THE White Black, and Green Wires!! (DONT CUT BLACK WIRE as shown in the pictures)


Step 3.
Go ahead and cut the red wire on the extension cable...Strip both ends.
Ok the extension cable is now ready...put it aside.. (DONT CUT BLACK WIRE as shown in the pictures)


Step 4.
Strip the spare wire. Both ends.

Step 5.
Unplug the cyberpower hub and open the battery panel on the back.
...first remove the outer most battery...I connected the space wire on the side of the little bump(positive side)..Try to find a place where you can connect the wire and place a small piece of electric tape on it. Make sure you dont put it directly on the little bump otherwise the batery wont be able to connect to the device. I made a little hole on the right side of the battery panel(i made the hole with a nail file) to let the wire out of the device and still allow me to close the panel.(we'll call this wire power from now on)



Step 6.
This is the hard part..it takes patience...
on the usb extension cable...
reconnect the red wires to each other by twisting them together...You might have to squeze the cable together a bit to do this...Now twist the red wires together with the power wire coming from the cyberpower hub(3 wires total)...




Step 7.
Now you might want to use that electric tape...and wrapt it around the connections. Dont wrap it too much...you want to try it out and make sure it works before finalizing it.


Step 8.
Everything should work now...plug the usb extention cable into the cyberpower hub and the other end into the Host cable. Connect a device into one of the 4 cyberpower usb ports...If the device you have works it should auto appear in your browser. Otherwise check your connections. If everything works i usually hot glue everything to PREVENT CONNECTIONS FROM moving or bieng pulled apart(you really dont have to do this)...I put electric tape afterwards to make it look better....

When everything is connected it should look like this....


DO NOT USE THE MODDED EXTENTSION CABLE TO CHARGE THE HUB!..You can charge it by PLUG IT IN DIRECTLY w/o extension cable or use a normal extention cable..ALSO KEEP THE MODDED CABLE UNPLUGGED WHEN YOUR NOT USING

I hope this helps someone...

holy crap! yeah pictures would help.

P.S. Can you explain why all of this is neccesary?

Whats with the battery powered hub, and why do you need to strip the extension cable?

thanks, i am technologicly informed, but i don't understand the need for all of this.

[cyberguest]

i can host the pics for u, send to <hidden>

ok so this is how it works...the USA H3xx does not send power through the USB host cable(via the media port) but all the other connections are in tact...

A normal usb device sends power to the device its connected....
So we have to replicate this function but not only do we need to have a the device powered we also have to send power back to the iriver(sending power back to the iriver powers up the essential componenets inside needed to do USBOTG)...

The battery powered usb hub allows us to make a three way power connection(power to the iriver, to the connected device and back to the hub)...but the question where do we make this connection??? so i chose to make the connection in the extension cable...alternative you can make the connection by opening up the usb hub which is more risky in my opinion....

The great thing about this battery powered hub is that the batteries are rechargeable...

I'm not sure I completely understand your mod but I'm wondering if I might be able to use this or a similar solution instead of moding.

I own a firewire PCMCIA card (for my Powerbook because my father fried my port checking the voltage) btw I cant remember what the voltage was?

It has 4 connections.

1.It has an external adaptor to provide voltage to charge a device (or power it) thru firewire.
2. PCMCIA card of course.
3. 2 Firewire ports (1mini and 1fullsize) to plug devices into

Of course you could just use the adaptor and the firewire plug without the pcmcia part and charge (I actually havent tried this)

Could a similar USB device be use to power the USH320 USB port on the H320?

Did i hear that you can mod this from the inside? where is this posted? that would be a lot more simpler, but involves opening it up. anyone have alink?

Skeil did it..freaken genius...
USB-ON-THE-GO works on U.S. H3XX！！！

Did your cyber power hub think it was charging(blue light on) when u plugged that cable in?

Yes.

Cool i think it will work then...as long as all three wires are connected it should work....

Also remember to keep the extension cable unplugged when your not using it...


BTW your cable looks alot cleaner and nicer thank mine

I didn't cut red cable but just removed isolation and twist around additional wire. i didn't even remove those silver wires and external isolation.

lol. U can even charge H3xx when u plug it to hub with moded cable.
U need to plug cable and turn on additional power from batteries at hub, and when u plug turned off H, its starting to charge from hub.
So, u gain not only usb on the go, but charger on the go too.

ohh i see what your saying

Not to confuse anyone but this is not to charge the batteries in the HUB...
You should not charge batteries in the HUB with the moded extension cable...

But you can use the moded extension(not plugged into anything but the hub) ....this will turn on the USB hub(blue light on)...so then you can switch on extra power switch on the hub(red light on)....plug the H3xx data cable into of the ports in the hub and the other end in the "data" port on the H3xxx...and the H3xx will start charging usb hub batteries ...

So this mod is like a 2 in 1...you get a battery pack(thats recahargable) and usb on the go...

exactly

This is what i have done:

The instructions and pictures are too complicated. You should only use pictures that are the acual mod and not put pictures and photoshop saying "This wont be here for you". Way too complicated and ununderstandable.... .

Sory but im not going to remake the cable exactly according to the tutorial...look at regie's cable pictures...its perfect...and thats exactly how its suppose to be....how are they too complicated??? what exactly dont you understand??

[romcabrera]

Will there be a "mod-from-the inside" tutorial? Modding the iriver from the inside, will make it work exactly as an International H320, no powered usb hub is needed, am I right?? Just the iriver, the cable and the external device I want to browse...?
