I already have it since 3 months I only wait for the big day

an interesting crash with clear fifos & routines call

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 changes needed for USB host to work.

virtual hub ?

2239 static int musb_h_start(struct usb_hcd *hcd)
2240 {
2241 struct musb *musb = hcd_to_musb(hcd);
2242
2243 /* NOTE: musb_start() is called when the hub driver turns
2244 * on port power, or when (OTG) peripheral starts.
2245 */
2246 hcd->state = HC_STATE_RUNNING;
2247 musb->port1_status = 0;
2248 return 0;

i see bus suspend mesages ( on my previous screen captures ) but bus resume has no code, no nothing.
is this ok ?? i think the bus in host mode never wake up and this is a big problem as i see enumeration is one time job.
if we are blessed with an "connect" interrupt something must happen in bus resume routine.

2257 static int musb_bus_suspend(struct usb_hcd *hcd)
2258 {
2259 struct musb *musb = hcd_to_musb(hcd);
2260
2261 if (musb->xceiv->state == OTG_STATE_A_SUSPEND)
2262 return 0;
2263
2264 if (is_host_active(musb) && musb->is_active) {
2265 WARNING("trying to suspend as %s is_active=%i\n",
2266 otg_state_string(musb), musb->is_active);
2267 return -EBUSY;
2268 } else
2269 return 0;
2270 }
2271
2272 static int musb_bus_resume(struct usb_hcd *hcd)
2273 {
2274 /* resuming child port does the work */
2275 return 0;
2276 }

KEEP up the good work guys I am waiting for the day to add a micro usb-usb adapter + 3g 850/1900 to get on att services rather then swapping sim cards every time i want to browse interent on the go.

In this case, this is a twl4030 hardware feature (not driver -- http://mxr.maemo.org/fremantle-20091...4030-usb.c#358 ) and we'd need to emulate that in software.

It might make sense as the usual trace is a_idle -> ... -> a_wait_vbus -> .. -> a_host.

i seen code a month ago .....but
come on ...both vbus & !ID true is missing
added bold my diff ( warn: only the idea not functional code )

354 /* STS_HW_CONDITIONS */
355 status = twl4030_readb(twl, TWL4030_MODULE_PM_MASTER, 0x0f);
356 if (status < 0)
357 dev_err(twl->dev, "USB link status err %d\n", status);

else if ((status & BIT(7)) & (status & BIT(2))
linkstat=USB_LINK_ POWEREDHOST /*must be added in enum linkstat */
358 else if (status & BIT(7))
359 linkstat = USB_LINK_VBUS;
360 else if (status & BIT(2))
361 linkstat = USB_LINK_ID;
362 else
363 linkstat = USB_LINK_NONE;
364
365 dev_dbg(twl->dev, "HW_CONDITIONS 0x%02x/%d; link %d\n",
366 status, status, linkstat);
367
368 /* REVISIT this assumes host and peripheral controllers
369 * are registered, and that both are active...

because when vbus=true => PERIPHERAL only
we need replace
.................................................. .......
374 if (linkstat == USB_LINK_ID) {
375 twl->otg.default_a = true;
376 twl->otg.state = OTG_STATE_A_IDLE;
377 }

else if ( linkstat==USB_LINK_ POWEREDHOST){
twl->otg.default_a = true;
twl->otg.state = OTG_STATE_A_WAIT_BCON: /* not shure if will work*/
}
else {
378 twl->otg.default_a = false;
379 twl->otg.state = OTG_STATE_B_IDLE;
380 }

waiting vbus rise is not needed to enter a_wait_bconn because vbus is here and state machine can jump directly into this stage

and a routine sensing D+ rise is needed for peripheral insert sense but must be started after one bus suspend condition

Sorry if this is already posted.. But has anyone seen this cable.
http://www.nokiausers.net/Videos-and...nd-Mobile.html

looks like a microUSB. and i guess it comes in the box with the N8.. Hope they put the cable in store before the phone..

There is already an adapter that looks like that, check here http://talk.maemo.org/showpost.php?p...postcount=1000
But yeah, a cable would be nice(although it looks short)

yup saw it but The cable looks beautiful and professional I am speaking as a End user though.
