Re: N9: It's finally here
Those who are distressed by a lack of keyboard:
There's many different kinds of BT keyboards for the iphone 4, just look on amazon. This might be hackable:

Re: [Announce] USB hostmode beta release
Wow, I dropped off the face of the earth and then this ... this is so impressive :) A word of caution: the usb connector broke off my n900 and I had to send it back for warranty service (the n900...

Re: N900 will not allow USB OTG!
If vbus and Id pin are applied at the same time, I believe vbus is prioritized. If you plug in id then power, I believe there is not another interrupt.

Re: N900 will not allow USB OTG!
Jimx,
I can't speak for others working on the project, but given USB is required for charging, I would prefer to take a little more time up front to check and minimize the number of software...

Re: N900 will not allow USB OTG!
Grouding the id pin sets the a_idle state, not a_host.
If I plug in power after I plug in a grounded ID pin,
/sys/class/i2c-adapter/i2c-1/1-0048/twl4030_usb/linkstat
does not change to read...

Re: N900 will not allow USB OTG!
I agree the ID pin shouldn't be necessary and I'm working on that right now.
On the subject of function traces, ftrace would be quite nice. I managed to get zImage to compile and run with ftrace...

I am typing this in from a USB keyboard hooked up to an external hub that I got working with just force host. It was not via the HNP trick.
I have tried different hubs connected directly. I can...

For anyone who has a peripheral at least half working: can you try
echo -1 >/sys/module/usbcore/parameters/autosuspend
to see if that stops the constant re-enumeration? By default that...

Re: N900 will not allow USB OTG!
Yup, we've known about the id pin causing an interrupt and by default switching to a_idle and also setting some sysfs file to read id (I forget which) instead of vbus. That only changes that...

Re: N900 will not allow USB OTG!
Also, once this is ready, to my knowledge there is no reason you couldn't kick all of this off via the id pin interrupt from the twl4030 and stop it when the cable is disconnected.

Re: N900 will not allow USB OTG!
HNP isn't workng for me; musb core goes into host mode but I don't get any urb or anything. Is a custom kernel actually required?

Re: N900 will not allow USB OTG!
OK. As I said, I was pursuing forced host mode which AFAIK does require kernel patches. I have those posted back a ways though I do not know if it's the right strategy or not. Have you had a chance...

Re: N900 will not allow USB OTG!
You're saying that CP.CAPP and CP.CAPM are not the relevant signals?
The beagleboard uses the tps65950 USB PHY. I thought the isp170x was used because it supported the battery charging...

Re: N900 will not allow USB OTG!
BTW I believe the schematic wiki page is incorrect - the id pin apparently is connected to the twl4030 and generates an interrupt. Otherwise the usb state machine would not be moved to the a_idle...

Re: N900 will not allow USB OTG!
Having not been able to see the schematic before posting that, I thought perhaps it showed the twl4030 as the phy. That's not the case.
So the twl4030 (cribbing from the tps65950 datasheet) can...
