Re: N800 USB Host Mode Experiment

Alright, after filing down the edges of my mini-A cable, it now fits the mini-b port in my n800.

Working / Working-ish:
Sandisk Cruzer Micro USB drive (mounts and filesystem works)
Apple USB keyboard - Typing possible, capslock doesn't light up but still works, errors about "USB hub not supported". Hub does in fact work - I can plug the Cruzer Micro into it.
BU-353 GPS - After insmodding pl2303 drivers, works fine with gpsd and maemo-mapper.
Nikon D40 - works, mounts card.

No driver yet, but appears to work:
USB Prism2 wireless card - Recognised - will have to compile driver and see what happens

No driver yet, not sure if it will work:
Keyspan USA-19 USB PDA Adaptor (usb to serial): Caused device reboot, shortly after unplugging. "USB hub not supported"

Not working:
Legend card reader - lights up, can't mount the SD for some reason. Might be because there are multiple units available...

Re: N800 USB Host Mode Experiment

I found a very cheap USB F-F adaptor that looks like it will work:

$1.48 with free shipping worldwide:

I've got one (and a whole heap of other stuff) on the way...

Re: N800 USB Host Mode Experiment -> micro A to USB A cable

First post:

This should be a cable that puts the N810 in host mode automatically:

http://www.reichelt.de/?ARTICLE=74220

"AK 676-AA : USB 2.0 A-Stecker auf Micro-USB A-Stecker 1m"

Shipping mainly to germany.

I didn't read this thread far enough so I wrongly ordered 2 of these
http://www.reichelt.de/?ARTICLE=74221 , which are micro B - USB A (same as the one that shipped with the N810)

I did not yet order the micro A - USB A one but maybe someone else can report.

**EDIT** : Ha! They sent me the wrong ones - that is: the RIGHT ones for automatic USB host mode: Micro USB B - USB A
And I can confirm that pluging the cable is enough to put the N810 into host mode & it recognized my PQI 4GB USB stick without additional powersupply.

this would be a KILLER app that would sell a boatload more N800/N810;s than has been sold.

one of the shortcomings on the Internet tablet is its reliance on Wifi where free WIFI is getting more and more scarce or pairing with an EVDO phone which is a little clumsy IMO.

it could be solved with the Wimax connectivity that was announced as a possibility. However, i;d rather be able to chose my own provider.

Re: N800 USB Host Mode Experiment

I have just received a cheap usb hub. I bought it since it has an external power socket, so I supposedly can connect (relatively) high power devices but I noticed that the dc port is just wired in parallel to the 5v line. Is that normal or I risk frying the tablet if I connect an external power source?

Re: N800 USB Host Mode Experiment

Wiring it that way would seem dumb, but the N800 probably is (& SHOULD BE) diode-protected. There's some risk associated, but I think not much.

Your tablet, your call.

Re: N800 USB Host Mode Experiment

USB host mode is the only thing keeping me from going back to OS2007.

I have ordered one of the nifty N800 USB OTG adapters announced in this thread. That should make things even better!

Re: N800 USB Host Mode Experiment

Got the Nikon Coolpix to work. Per Jolouis' suggestion, moving over from "dongle" thread. I got the Nikon to read on the N800. Though the camera was working, I put new batteries in and then took a picture with a newly formatted CF card. That did it. I think the new batteries are what mattered. I'm gonna try a powered hub with the other two devices, and I'll update. Thanks for the reply Jolouis.

Re: N800 USB Host Mode Experiment

Hi, I have done all things about USB-Host and USB- OTG with Mara's guide. I have bought a f-f usb adapter and plugged in one side to the nokia dke-2 cable and plugged in to cable to the n800. Then switched device to USB-Host mode and plugged in my bigboy 2gb flash memory to the f-f adapter but it didn't worked,no light appears. After this I tried another flash memory Twinmos 512mb and it worked like a charm. Since I thought Bigboy needs more power I bought digitus powered usb hub and tried with bigboy but nothings happened again and it didn't worked.When I connect the usb hub "usb hub not supported" message appears. What can I do for fixing this problem? Is there any usb hub driver etc. for n800 OS2008 that I must install? Because, n800 didn't recognize the usb hub. Am I doing something wrong or missing something?
Thanks in Advance

Re: N800 USB Host Mode Experiment

go into xterm and type "dmesg" after plugging it in and getting the unrecognized messages. It may be a partitioning problem. dmesg will show what the USB is trying to do and what it finds (and probably why it won't mount)

Re: N800 USB Host Mode Experiment

Can you try the drive without the hub? Is bigboy the brand name?

Can you plug it into a Linux system and get the USB ID information?

(I noticed there are a few extra USB mass storage drivers which aren't normally necessary, but this could be one of those cases).

Re: N800 USB Host Mode Experiment

@tz1,
I already tried without hub and nothings happened. I don't have linux on my pc but may be I can try with the bootable linux cd version. After this How can I download these extra usb mass storage drivers? Yes, Bigboy is the brand name. By the way, I gave the digitus hub back to the store and I bought Sandisk Cruzer Micro 2gb flash memory. As I guess it worked very good without hub:).
Thanks

Re: N800 USB Host Mode Experiment

Everything works with a powered hub now. Just an update on my previous post where I was having trouble getting the N800 to recognize a powered external HDD and Flip video device. Got an i-rocks 4100 hub from newegg for 10.99 US shipped, and everything now is recognized just fine using the SW host mode switching. Can't play movies directly from the HDD on the go as I need to plug in, but easy enough to use a 2gb flash drive as a go-between.

I just came accross a USB IRDA adapter. Has anyone had any luck with these?

Re: N800 USB Host Mode Experiment

News to all that care ( and even those who dont ) I have the 4port power-injected hub all done. working and happy. As I am moving 87.12 miles away the next 2 weeks of my life are going to be booked. But then I will make another more streamlined version (this one has bits of melted plastic and just look like *** But it works.) so Along with that I will do step by step photos along with a cost sheet. And then I can either build you one (5 bucks over cost +s/h cuz face it it is a pain in the rear to make) or you can build your own, I am pretty happy with mine Cant wait to try it out on some really fun stuff!!! woooo! lata. Feel free to E-mail me if you find you can not wait 2 weeks for this...

Re: N800 USB Host Mode Experiment

can you post photos of the current one?

How to make menu items in Extras

I'm going to update the wiki due to an error in mara's code that qwerty12 found. I think this is as easy as unziping and moving files around. See if you have any comments to add. I also created icons to reboot and sfdisk the SD cards, I'll add those to a future wiki on how to create application menu items.

To Install vi (or other editor)
1.a. If you have the right repository (anyone know which one?), a vi editor shows up as in Application manager - Tools -vim version 70 5.79 MB
1.b. If not, try http://www.cs.cornell.edu/zlt/maemo/vim_6.4-1_arm.deb (wouldn't install for me after uninstalling vim)

Before we begin, you must have vi [link] installed and be able to gain root [already covered above]

1. Launch x-term
2. vi /home/user/MyDocs/Otg.sh
2.a. press i to edit
2.b. paste code

Code:

#!/bin/sh

# usb otg mode script

# use gainroot to become root and relaunch itself

if [ `id -u` != 0 ] ; then

# if not already root, call itself as root

sudo gainroot <<EOF

$0 $*

EOF

exit

fi

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

2.c. press Esc (hardware key below d-pad, or on vi screen)
2.d. save by entering :w (: is next to capital L in shifted menu)
2.e. exit by entering :q
3. chmod +x Otg.sh

repeat for Host.sh with this code:

Code:

#!/bin/sh

# usb host mode script

# use gainroot to become root and relaunch itself

if [ `id -u` != 0 ] ; then

#if not already root, call itself as root

sudo gainroot <<EOF

$0 $*

EOF

exit

fi

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

From this point you can use Status Bar mentioned below, personal toolbar and/or continue to make an Icon.

1. Launch x-term
2. sudo gainroot
3. vi /usr/share/applications/hildon/otg.desktop
3.a. press i to edit and paste the following code

Code:

[Desktop Entry]

Version=0.1

Encoding=UTF-8

Name=USB Otg

Type=Application

Comment=USB On the go mode

Exec=/home/user/MyDocs/Otg.sh

X-Osso-Type=application/x-executable

3.c. press Esc (hardware key below d-pad, or on vi screen)
3.d. save by entering :w (: is next to capital L in shifted menu)
3.e. exit by entering :q

again, repeat for host.desktop

Code:

[Desktop Entry]

Version=0.1

Encoding=UTF-8

Name=USB Host

Type=Application

Comment=USB host mode

Exec=/home/user/MyDocs/Host.sh

X-Osso-Type=application/x-executable

Re: N800 USB Host Mode Experiment

The tablets start with vi. You can install vim, but it's not needed or helpful for this.

However, if the goal is just to paste text into files, cat is even easier:

Code:

cat >targetfile
Paste stuff into xterm.
Tap Ctrl.
Enter 'd' in the editbox and click OK. (Or just tap d on the keyboard, if you're using any xterm build other than stock Chinook...)

Or, if control chars are considered a problem, use a here file:

Code:

cat <<E.O.F >targetfile
Paste stuff into xterm.
Type E.O.F<enter> on the last line, by itself.

Re: N800 USB Host Mode Experiment

Nice, even easier. If someone wants to change directories they can copy past somewhere else first to edit.

To create OTG host buttons:

1. Launch x-term
2. cat >/home/user/MyDocs/Otg.sh
2.a. paste code

Code:

#!/bin/sh

# usb otg mode script

# use gainroot to become root and relaunch itself

if [ `id -u` != 0 ] ; then

# if not already root, call itself as root

sudo gainroot <<EOF

$0 $*

EOF

exit

fi

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

2.b. press Ctrl and enter a lowercase d.
3. chmod +x /home/user/MyDocs/Otg.sh

repeat for cat >/home/user/MyDocs/Host.sh with this code:

Code:

#!/bin/sh

# usb host mode script

# use gainroot to become root and relaunch itself

if [ `id -u` != 0 ] ; then

#if not already root, call itself as root

sudo gainroot <<EOF

$0 $*

EOF

exit

fi

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

From this point you can use Status Bar mentioned below, personal toolbar and/or continue to make an Icon.

1. Launch x-term
2. sudo gainroot
3. cat >/usr/share/applications/hildon/otg.desktop
3.a. paste the following code

Code:

[Desktop Entry]

Version=0.1

Encoding=UTF-8

Name=USB Otg

Type=Application

Comment=USB On the go mode

Exec=/home/user/MyDocs/Otg.sh

X-Osso-Type=application/x-executable

3.b. press Ctrl and enter a lowercase d.

again, repeat for cat >/usr/share/applications/hildon/host.desktop

Code:

[Desktop Entry]

Version=0.1

Encoding=UTF-8

Name=USB Host

Type=Application

Comment=USB host mode

Exec=/home/user/MyDocs/Host.sh

X-Osso-Type=application/x-executable

Just use osso-statusbar-cpu and create custom commands calliing your two scripts. Be sure the 2 scripts are included in your /etc/sudoers file, of course.

How do I get the files into that folder? I don't see it in the File Manager.

File manager cannot see /etc/sudoers. You have to use emelfm2 or a different file manager.

That thing looked pretty, but the shipping is too deep, item is $9.99, s/h to NC is $10.23 makes the adapter total $20.22 for a jack, what a jack.

Re: N800 USB Host Mode Experiment

Received the USB adaptor made available by Jolouis and plugged it into my N800, running under an unmodified OS2008 version 4.2008.36-5. Connected a standard Canon digital camera USB cable between the adoptor and the Canon. The N800 responds with a "USB device not Supported" message followed by a second msg stating " Unable to connect, no file system available" . Am I doing something wrong??
