Tutorial: How to get USBOTG to work with US iriver H3xx - Page 3

Project-2501 · #81 (**permalink**) January 26th, 2005, 05:34 PM

I just created external battery pack using a nine volt and a power regulator, how would I make a usb on the go "hub" using my battery pack and two female usb cable connectors?

Hi all

Under the downloads/gallery link on this site, there is a video demonstrating USBOTG, from a digital camera, to a H300 - US version (it has the mini USB ports).

Does this mean USBOTG is actually possible with SOME camera's ? (I'm assuming you still need the Korean Firmware).
I have read all the threads on the mods required for USBOTG, so it seems strange to have a video on this site demonstrating USBOTG with no devices - what have I missed here ?

Also, someone mentioned using a SyncBox. This gadget looks like it may pass power through to the H300 if connected, but thats just a guess - has anyone tried using a SyncBox ?

Thanks, and keep up all the great work with the posts - I'd have an expensive FM radio without you all !

SyncBox != USBOTG!

From what I understand, a Syncbox would work (in theory) - provided both devices support USB Mass Storage (the iRiver does). You wouldn't get the functionality of USBOTG, however - as the syncbox simply copies X to Y - and blindly. (Disclaimer: Speaking in theory here).

USBOTG on the iRiver device provides a browser and other functions to allow you to pick and choose your files, destinations, etc. It's not perfect, but it does the trick.

The iRiver H3XX only speaks "USB Mass Storage" over USBOTG. Some digital cameras use the "USB Mass Storage" protocol - sadly (for us), many use another standard protocol developed for digital cameras, or a manufacturer specific protocol. Digging in the Device Manager in Windows will help you find what protocol your USB device is speaking if you know where to look.

And, as said a thousand times, devices won't work without some sort of power injected into the connection. To get the power flowing, use any of the mods listed on this site.

(Appearently some hard-drive enclosures and maybe other devices will work without the 5V mods, but you're on your own there. It's safe to generalize and say all devices need the 5V, if only to signal that another device is connected. YMMV, but it'll be dumb luck if it does.)

I connected a mini usb cable (liked the the connector that goes into iriver) and a female usb connector. The green is wired to the green and the white is connected to the white. The same goes for the red and black wires. The red and black are also connected to a battery and a voltage regulator (positive to the red and negative to the black). Nothings happening. Need help.

Yeah you're absolutely right
However, there is now a Syncbox II (which I'm not sure has been officially released) that allows you to choose which files to copy, so that effectively does give you USBOTG

Not that anyone's ever tried one...

Looks like a neat device. If it can speak to Digital Cameras using PTP (Picture Transfer Protocol) as well as USBMS (USB Mass Storage) then it'll certainly be bought and popped into my gadget bag as soon as it comes out.

The iRiver H3XX lacks PTP support - which is pretty much what's preventing it from talking to a much larger percent of digital cameras out there than it does currently.

Try grabbing the power from the red and black (only!) from another USB cable plugged into a PC or Laptop and see if that works. Leave the other ones as you have them.

It should be plugged into the Media port on the iRiver.

Make sure you're in browser mode.

What devices are you trying? A good "will likely work" device is a USB Thumbdrive - they generally will fire up. Good to test with.

Without more info I'm afraid we can't really help you further.

OK, so there's a way of modifying a US H320 for USBOTG internally here
http://godzilla.disca.upv.es/~spetit...ooded-h320.jpg

The picture clearly shows L40 against the missing component, which implies that its an inductance (coil).

Has anyone taken a look inside an International H300 to see what the component actually IS (how its labelled, more particularly)? That way the proper component could be installed rather than a piece of wire that seems to be originating from "somewhere else" in the circuit.

There is a possibility that the inductance is linked to some form of AC circuit and is being used as a voltage multiplier to increase it a bit, but I suspect its just there to prevent high frequencies (aka the data!) being reflected back into the H300 from the USB cable.

[by the way "hello everybody" - I've been following MR for a couple of months now, and my "Christmas present" of a US H320 finally arrived a couple of weeks ago

)

NeilW · #90 (**permalink**) January 29th, 2005, 11:39 AM

From the pictures it looks like there are 3 components "missing":

The coil L40, which I think is a 6.8uH, from its lable

CE12 Electrolytic capacitor 0.01uF perhaps

Q3 (Q normally denotes) a transistor, but I can't find it from its lable...

There could also be 3 resistors missing to the left of Q3, but its hard to tell from the photo...

R55 and R137 look like they are arranged differently too...

Wonder what that bit of the design does? Anyone else any ideas?

Quick Recap: I have made a modded cable with a radio shack USB-A mini cable and a 4xAA battery pack. I connected the battery pack from + to the red wire and - to the black wire in the USB cable.

The US iriver H320 with Korean firmware upgrade now can browse the files on my 2 card readers but when I try to copy files (JPG) it gives me a copy error and is unable to read them. Even a PC cannot read the copied files.

I am wondering if anyone else has experienced this problem. Should I try more card readers?

Thanks,
Siri

1. open up the iriver

sirroot(or anyone else), although you've seemed to answer this question already, I'd just like clarification. If I do the internal mod on the US H320, and upgrade to firmware 1.27, I'll still be able to use USBOTG. I mean I wouldn't mind doing the external mod either but it seems like a lot of extra stuff to carry around.

Thanks

Hi all !

Somebody can tell where I can find a Cyberpower 420mp hub online or in store ? (I found almost nothing with Google) If it's possible it will be better if it's in Canada.

Thanks !

Okay ! Thanks for the info.

I see many people here go through a great deal of trouble to turn a US H340 to an international H340 to get video, otg, etc. Is that a good thing to do?
My point is: Can a US model do something a non-US model can't do? (such as sync with Media Player more easy, run like an external HD, support more file-types, etc)

enewmen · #98 (**permalink**) February 8th, 2005, 01:19 AM

More simple question:
I know this is a H340 thread. However..
Can the US-PMP140 run OTG? If so, I think the PMP does EVERYTHING better than any version of the H340??
Please correct me if I am badly mistaken. I hope to get some responces before I buy a player..

thanks!!

the u.s. model can play drm protected music.

not sure about the pmp, but one thing it cant do as well as the h320 is fit in my pocket

This is irrelevant to the topic of this forum but i'm in a panic so i'm just posting it here.

I opened up my h320 (U.S. model, 1.27k) and took the battery and the rubbery things out (didnt detatch any wires) and just looked around at the hard drive. I disconnected the hard drive to have a look at the specs. then i put it back together exactly how it was before, thats it. now hard drive won't spin up when the unit is closed up tightly, but it will boot up fine when i have the thing split wide open with its guts spilled out and everything connected.

HELP ME

I have a US H320 modded with 1.27K formwrre. I used a much smaller USB hub (which had as optional power-in jack and I powered it with 6v from a battery pack) and modded cable with "red" wire connected to battery pack. Using a jumpdrive through the hub worked seemlessly and I was able to transfer files to and fro as well as delete files on both HOST and DEVICE. However, I cannot get my Memory Stick card reader to work. I tried 2 different card readers - a 15-in-1 and a smaller SD/MS card reader, but in both cases, going into Explore on H320 causes it to recognize a plug-in device and the card reader shows starting an access, but eventually does not show the DEVICE in IRiver. The access light on the card reader which came on after starting Explore on IRiver stays ON after that.

Any ideas on USBOTG compatibality of H320 with card readers? Should I try a different card reader? What should I look for in the card reader to be compatible/work-with H320 USBOTG? Btw, as I mentioned above, I tried 2 different card readers and they were both "compatible" with "USB Mass Storage".

Thanks and regards,

Add one to the tally of working US - USBOTG units.

I followed the original tutorial, and I would like to make one addition:
To save yourselves from the grief that I had of restripping the red wire and my telephone (power) wire, TAPE YOUR CONNECTIONS AS QUICKLY AS YOU CAN. Those thin wires are very delicate, so do yourselves a favor and tape very soon after making the connections.

My Dazzle USB 2.0 CF card reader worked flawlessly!
Thanks for posting such a good tutorial.

P.S. iRiver surprised me: the host cable came in nothing but a bubble padded envelope, no box. On the other hand, what else whould go into this box?
