Re: N900 will not allow USB OTG!
 

It does NOT allow USB OTG.

It does allow USB Host mode (without OTG) as I understand.

Be patient and take in account that the code isnt working for everyone, and we still dont know why

Re: N900 will not allow USB OTG!
 

Maybe a beta should be released to let the users check the HW versions on which it works.

Re: N900 will not allow USB OTG!
 

The N900 can power attached devices (up to 200mA) by itself.
If g0dzilla's approach only worked with a self-powered hub, then it is not
surprising and known to work.

We are looking for the "real" hostmode without any prior connection a PC or hub.

For those who got it working somehow: could you please post the output of
http://maemory.com/N900/kernel/usbwatch
(requires installation of coreutils-gnu, start it before your experiment).

Re: N900 will not allow USB OTG!
 

Is it worth someone writing a "Test" utility that can be easily installed?

People can install it and then report back the results via a generated text file?

It does not have to be a full working version of hosted USB but maybe a data gathering exercise?

Re: N900 will not allow USB OTG!
 

Perhaps a binary should be given via PM to those who PM their hardware version first.
There was some way to find that out via the maemo flasher.

Sorry for the off-topic.

Re: N900 will not allow USB OTG!
 

could all of you please stop spamming this thread?

the patch is not well understood and even completely buggy as far as I can tell!!
the "it works!!11!" announcements are just random lucky people and it's not reproducible. So no reason to "beta-test", this is not even alpha.

Re: N900 will not allow USB OTG!
 

Cable questions.

1) If I modify standart client (non-OTG) cable by soldering pin 4 to pin 5, could I still use it as a client cable to connect n900 to a PC ?


2) I would like to create a 3-female usb pattern: one socket for the OTG cable, one socket for the power cable to a USB-charger and one socket to connect the client device. Can I wire the usb-power directly to the red and black cables (+ and gnd) inside this circuit? Or will it burn something and some diodes should be used? Not aware how active usb hubs are ususally wired.

Re: N900 will not allow USB OTG!
 

You still think it's a defect eh?
BTW, reproducibility on my device dropped from the 100% I reported earlier. I can get to devctl=dd easily, but power=f1 isn't working anymore.

Oh and I agree with your suggestion on closing this thread and taking it 'elsewhere'

@ h-e-n crew

i saw in hostmode-working.sh bme is stopped after "echo"s and about sequence of echos ....... long story

my proposal: ( without pc )

stop bme # ( for god sake )
echo host >/sys/devices/platform/musb_hdrc/mode
echo H >/proc/driver/musb_hdrc
i2cset -y -m 0x07 2 0x6b 0x01 0x05
echo I > /proc/driver/musb_hdrc
echo F > /proc/driver/musb_hdrc
echo e > /proc/driver/musb_hdrc
while true; do sleep 28; i2cset -y -m 0x80 2 0x6b 0x00 0x80; done
