USB device found found at bus 001, device address 018
unsupported board (id = 0x0000)

can anyone tell me whats wrong?

This looks fishy. So your device boots and works fine but you are unable to reflash the device?

I'd suggest to try different computer or boot linux directly (i.e. no vmware) and try again. If the problem is realy in your 770 and not computer you may try to play with som flasher parameters

what device version you have? what you see when you run flasher -i as root? I see
then you can try to force hw revision

I don't know what is the syntax of those arguments. For my 770 product code is SU-18 and HW revision is 1602, so I guess for my device I could force hw revision an flash firmware via
flasher-3.0 -h 1602 -F ....bin -f


You can also try to flash your device with 0xFFFF flasher, maybe it doesn't verify board version and allows you to flash even with board id 0.

oh, BTW, the thread title 'Usb host mode trouble' was not very good choice. How it is related to usb host mode? Maybe you could get more answers with more descriptive title with words like flasher or unsupported board ID 0x0000.

Thanks a lot fanoush for your reply, here are answers to some of the questions I could answer (from a very tough question paper, I am a newbie in linux)

So your device boots and works fine but you are unable to reflash the device?

My device works absolutely flawlessly with tons of applications (booting from 2gb mmc) in it except now, when I plug in with the usb cable with the computer it doesnt show up on 770. Reflashing didnt solve the issue.

I'd suggest to try different computer or boot linux directly (i.e. no vmware) and try again.

I have tried this with Damn Small Linux cd.

what device version you have?

hw build 1802

what you see when you run flasher -i as root?

root@ubuntu:/home/ubuntu/Desktop# ./flasher-3.0 -i
flasher v0.8.7 (Oct 17 2006)
Suitable USB device not found, waiting
USB device found found at bus 001, device address 00
Found device SU-18, hardware revision 1802
NOLO version 0.9.14
Version of 'sw-release': <no version>

then you can try to force hw revision

How do I do this? do I do it on the computer or the 770?

I guess for my device I could force hw revision an flash firmware via
flasher-3.0 -h 1602 -F ....bin -f

what do the dots (....bin) stand for?


You can also try to flash your device with 0xFFFF flasher, maybe it doesn't verify board version and allows you to flash even with board id 0.

can you please tell me how to do this? the .deb file doesnt get installed in DSL enviornment?does it? how to install(?) it so that I can run it (?)

Perhaps that's because you enabled usb host mode? So after all the title of this thread is reasonable? In that case you can disable it via You can't use usb storage functionality when 770 is switched to usb host mode.

Oh, so you no longer have that problem with unsupported board id 0x0000 mentioned in first post? Then disregard all the rest with forcing hw revision, 0xFFFF etc. it i dangerour and you don't need it if flasher works.

Maybe when you see the "unsupported board id" it is because your 770 is fully booted? You know you can't use flasher when the device is fully booted? Flasher only works when device is completely powered off (no charger attached) and then powered on with usb cable attached and flasher waiting. And you should also hold the Home key when you power on the 770 if you are using vmware. With home key pressed on boot 770 waits for flasher indefinitely. VMWare may need it, it is slow with usb device detection.

Perhaps that's because you enabled usb host mode?

fanoush, thats the whole point. Remember in the PM I told you that after flashing with flasher-3.0 I got a msg that its in usb mode in 1st line but was immidiately followed by errors and it said the task was not completed. So, I did not get any green texts on my tablet switching on the host mode.

So, what I have right now is kind of a ..what should I say...eh..a transexual tablet (tt) which is neither in host mode nor in peripheral mode.

Oh, so you no longer have that problem with unsupported board id 0x0000 mentioned in first post?

I am still getting the unsupported board crap (id=0x0000) whenever I am trying to use the flasher to put in either host/peripheral mode. I have tried both. But everytime I get the same error. So, I flashed the device with nokia flasher with new OS2007HE, but I still get the same stuff and moreover the USB icon is also not showing even after a clean install of OS2007HE.

Oh, I see so you got this message if and only if you use
flasher-3.0 --enable-usb-host-mode
flasher-3.0 --disable-usb-host-mode
but all other stuff (flashing firmware, --enable-rd-mode, --query-root-device etc) works fine with same flasher binary, is this correct?

That's strange, usb host mode is just a flag as any other (r&d mode, root device, serial console flag, lifeguard). So it is pretty strange this fails and other ones work fine. Well then maybe using 0xFFFF would be interesting to try. 0xFFFF -U 0 should disable host mode. You can get static linux binary from here http://fanoush.wz.cz/maemo/0xFFFF-0.3.1-bin.tar.gz
Just extract it with tar on linux PC and run ./0xFFFF -U 0 as root.

Also as usb host mode is just a flag tested at boot time you could in theory modify startup sequence to ignore it or switch the device back to peripheral mode later at boot time.
Does this script work for switching modes after your device boots?

Well it seems that
flasher-3.0 --enable-usb-host-mode --reboot
only gives the unsupported board(id= 0x0000)
but when I do
flasher-3.0 --enable-usb-host-mode
It says that it is now in usb host mode but I dont get any green texts on my tablet after that. Connecting to computer doesnt show any usb icon and connecting a 5v power injector usb hub thru Y cable doesnt show the usb icon either.
What could be wrong?

Thanks a lot for your help so far.
