Re: USB 2.0 OTG on N810
 

Perhaps someone can find a retailer for this:

Re: USB 2.0 OTG on N810
 

GOOD find! I searched their site for a long time and did not find that. I did inquire as to if they would have a female to micro male and they said no.
Perhaps if enough of us ask for it they would start stocking it.

Re: USB 2.0 OTG on N810
 

Wouldn.t you still need a female to female for most applications?
The n810 comes with a male USB to male micro.

Re: USB 2.0 OTG on N810
 

Ideally yes, but I'm looking for pocket-sized options. This coupled with a short F to F cable would work for most products.

Re: USB 2.0 OTG on N810 - SUCCESS!!
 

Got my A-female to A female adapter from Directron.
Plugged it in to the Nokia supplied Micro to USB data table and a 2GB thumb drive - no work, no light.
Followed the excellent instructions at the wiki,
it complained but was recognized immediately!!

Gad the power and utility of this device increases daily.:D:D

Re: USB 2.0 OTG on N810 - SUCCESS!!
 

Hmmm... that WiKi page seem empty? :confused:

Re: USB 2.0 OTG on N810
 

Don't know what I did, try this:

And Mara - it seems to be mostly your fault this works so WELL :)

Re: USB 2.0 OTG on N810
 

My "standard" external 2.5" 120gb drive works* when plugged to its own power supply AND with the N810 connected to its own power supply, so I'm interrested: did someone try an OTG drive like this ?
* with the "USB hacked" cable discussed in the forum

Re: USB 2.0 OTG on N810
 

Anyone tested this kind of storage ? (i.e. OTG disk drive ?)
thx,

Software installed, Cables purchased, NOTHING works
 

I have the N810 running the latest version of OS2008

I have carefully read every post and every link and done additional searching. I believe I have everything setup correctly. I have the 'host' and 'OTG' apps in my extras. I select 'host' and then plug in my Nokia cable (microUSB to standard USB), the Fem/Fem adapter and then a range of USB devices. Nothing works. When I plug in I get the initial message:
"USB device not supported"
Then I get another box saying:
"Unable to connect, no file system available"
A USB sysmol appears in the Statusbar. Selecting this shows the following:
Connected to mass storage device (greyed out)
Disable mass storage device (avaialble to select)

Devices I have tried:
2 different USB SD 'jump' drives with 2gb SD and 4gb SCHC cards
An xD USB 'jump' drive
Canon S3-IS camera
A stand alone multi card reader with 4gb MiniSD SDHC card
The last reader is the only one whre the green LED goes on and stays on. The otheres either dont light at all (xD drive) or go on for a moment and then go out.

QUESTIONS:
What am I actually going to see if and when it does work?
Can I 'see' the extra card in the N810's file manager?
If so what should it be called?
Do I need to go to xTerm to see it?
Will it be visible to the media player?
What might I be doing wrong?

HELP! after hours and hours of reading and installation (hacking more like) I am so close but so far...

Derek.

Re: USB 2.0 OTG on N810
 

derek...

1. start your IT
2. launch xterm
3. log in as root
4. execute:

echo host > /sys/devices/platform/musb_hdrc/mode

5. attach your usb cable
6. plug in your usb device

- i have successfully attached:

various USB thumbdrives (using a female<->female adapter)
a Maxtor One-Touch 120GB USB hard drive (via powered mini-hub)
Sony Cyber-shot® DSC-S700 digital camera
Cowan iAudio G3 mp3 player

- and using 'normal' mode (i.e., Otg mode):

no-name USB RS232 adapter (using usb-serial kernel modules)

- btw, after you're done with host mode, don't forget to execute (as root):

echo otg > /sys/devices/platform/musb_hdrc/mode


have a happy and happy hacking!

Re: USB 2.0 OTG on N810
 

When it works, File manager will autostart and bring up the new drive.
It'll be named by its volume label.

Re: USB 2.0 OTG on N810
 

The file manager will not see NTFS or Linux FS. Format the SD with FAT32.

Re: USB 2.0 OTG on N810
 

- the file manager will see ext2 (my Maxtor was partitioned and formatted HFS+/ext2 - the ext2 filesystem appeared in the file manager w/no probs)

Re: Software installed, Cables purchased, NOTHING works
 

I use a F2F and when I put it in host mode it says "USB device not supported" and then I can access the THUMB drive.
What is a "jump" drive?

Re: USB 2.0 OTG on N810
 

Linux_author, thanks for rapid relpy!

I issued the echo command as directed and tried my standalone reader. It worked!
A bit more investigation revealed that I just had not hit on the right hardare combination. My reader wont see a miniSD SDHC card in it's mini slot (which is what I tried before) but it WILL see the miniSD card when inserted in the full size SD adapter and then put in my reader. In fact it will see any SD card in the SD card slot of this reader (1gb, 2gb 4gb). None of my jump drives work at all (too power hungry I expect).

BTW, the OTG and host apps in extras do also work now I know what card/reader combination works.

Thank you very much for taking the time to reply.
"When you know the key works, you try a bit harder to open the door"

BTW2 if anyone else wondered what you see when it does work, the file mamager opens automatically and describes the card by its size in the left hand list. Clicking any valid file will invoke the applicable app.

Also, the "USB device not supported" message DOES appear but the "unable to connect, no file system available" message does not if everything works.

Re: Software installed, Cables purchased, NOTHING works
 

'Jump' drive just one term used for a 'thumb' drive. I think every manufacturer has a slightly different name. I use the ones that take an SD card rather than dedicated internal memory.

BTW as you may have seen from my previous post it's working.

Also I discovered the file system requirement. I could not see some FAT16 CF cards in the reader that otherwise works. Thanks to the poster for this clarification.

Derek

P.S. I guess I'm off to meritline for one of their 16gb SDHC cards for $69
http://www.meritline.com/a-data-16gb...ash-card.html:)

Re: USB 2.0 OTG on N810
 

The meritline card works as the internal card in the n800. The URL works if you remove the trailing colon, http://www.meritline.com/a-data-16gb...lash-card.html

For my n810 I use a mini-to-micro SD and an 8Gb sandisk microSD http://www.dz-tech.com/sandisk-8gb-m...age-p-951.html


Note on multireaders - they normally enumerate as separate logical units or separate drives and not all of them may be automounting. One Belkin wouldn't find the SD reader directly (I could go into xterm though). Under windows it would give E: F: G: H: or something similar. So if you have a multislot reader, it might be compatible, but you would need to tweak something elsewhere to get the card to mount automatically.

Re: USB 2.0 OTG on N810
 

I did the above operation on my N810 and it said the USB device wasn't supported when I connected a USB flash drive. It also said there was no file system on the drive. But there is a file system on it. I attached a USB hard drive with separate power and it saw nothing. I used a female to female adapter on the end of the provided USB cable to connect up the flash drive. Does it require something else to connect properly?

Re: USB 2.0 OTG on N810
 

- most excellent! now to do more experimenting with various hardware?

:-)

- btw, i wish there was some way to collect a repository of working devices... it would be easy to gauge non-hub requirements based on voltage requirements of individual devices, but few manufacturers put that type of information on consumer packaging...

- when i use a powered hub, i've found that i must use this approach:

1. attach power supply to hub
2. then attach to IT via USB
3. wait for hub message, and then
4. plug in the device (such as USB hard drive)

- digital camera support may be more hit-or-miss... while my cheap Sony worked [i.e., mounted] with no problem, my Canon A570IS did not... (but then again, the Canon support was also squirrely under on my older Ubuntu boxen)

:-(

Re: USB 2.0 OTG on N810
 

- btw, i wish there was some way to collect a repository of working devices...

I had the same idea! Since none of my 'small' SD card THUMB drives work I am now looking for a good, compact single SD card reader. I'm sure others have found some that work.

I wonder if the mods know a way to craete a list by category that users can update here on ITT???

BTW, just saw a good price on a MicroUSB to standard USB cable from Newegg $2 + $5 S/H.

http://www.newegg.com/Product/Produc...rp.-_-12189164

I believe it is similar to the one that came with teh N810.

"I never generalise"

Re: USB 2.0 OTG on N810
 

Something else you can try when attaching USB devices is to enter the command in an xterm window. This should list something meaningful for the attached device such as maybe its name or just an ID. It gives some idea that the device is found on the USB port even if it isn't talking to it.

Re: USB 2.0 OTG on N810
 

Hi guys,

may I ask a short question:

Did anyone already got an usb-webcam to work? It would be a great opportunity to use a higher-quality-model when you are at home ...

btw: what are the chances of using a webcam without a powered hub -> are there such models? if not, is there any-possiblity to buy some mobile powered hub, like a battery pack with an usb hub directly attached to it?

Regards

Re: USB 2.0 OTG on N810
 

NTFS is not supported. Tried to attach my new Maxtor external harddisk.

Re: USB 2.0 OTG on N810
 

NTFS would probably function if ntfs.ko is loaded, but you would have to recompile the kernel normally to get it. hfsplus works, but the problem is with the Mac partition scheme, which can't be fixed by loading any module. CD/DVD drives work with ufs and isofs installed with the extra SCSI drivers (usb uses the SCSI command set).

Re: USB 2.0 OTG on N810
 

It is also slightly cheaper here
http://www.dealextreme.com/details.dx/sku.6764
$4.66 + no shipping fees (but long delivery)

Re: USB 2.0 OTG on N810
 

Should we have a driver or something for our thumb drives? Why do we get thet error msg when connected? :(

Re: USB 2.0 OTG on N810
 

Hi,

I tested it with an usb keyboard and a 7in1 card reader wirh 4Gb CFII card.

The keyboard works but it is an spanish layout keyboard and is working like a generic keyboard, i don´t know how to configure it but cotinue looking for this.

The card reader does not work yet

PS. Excuse my english but i'm not native
