No idea about the windows version of the flasher. Setting the host/slave mode via the flasher is persistent between boots. As mentioned you can still switch to slave mode on the fly via the given echo command, but rebooting will switch it back to whatever the flasher has set.

Thanks for the info.

Using the DSL-LiveCD I was able to use the flasher in an easy way (Thanks to quingu).
Now dmesg tells me a host is there, and also if a USB cable is connected.
But now there is no USB notification in the status area of the desktop anymore.
Regardless if I plug or unplug the USB cable, no USB symbol...

Also, the keyboard doesn't work yet using the hub.

Theoretically it should, since all the +5V lines inside the hub
are straight connected on the pcb, as is with the GND lines.
So if I plug in the mains adapter, the +5V lines of every port
has +5 Volts, actually +5.09 volts, with Nokia 770 connected.
And the manual of the hub says it delivers up to 500mA to the ports,
as long as the mains adapter is connected.

At least from this point there should be no need for another power injector,
or am I wrong here?

Or is there another software or configuration thing I missed?

I additionally tried the echo host... cmd as root, but no difference so far.

Thanks for your help.

if the hubs powered, it will most likely output the power to the outgoing ports, not the "host" port. you either have to solder or use a Y-cable where 2 sides connect the host-port of the hub and the 770 and the third goes into an outgoing port of the hub, thus getting power out of it.

if you want to use the 770 via usb w/ your pc, you have to temp. disable host mode.
goto xterm, gain root access then enter

echo peripheral > /sys/devices/platform/tahvo-usb/otg_mode

Does anyone sell the cable for the USb host mode, or do I have to make my own?

I prefer to purchase something than hacking cables together ???

I would probably blow up my 770 with crossed wires

have fun with google. check webshops for cables/adapters. use the forum search.

on the other hand... i did mine by hacking, its doable. if you do it concentrated and make a plan what exactly to do, chances are it works.

Hi all,

thanks for your help on hardware topic!
Finally I got the 770 to work with my USB keyboard:-)
It would have worked a few hours earlier,
if I only didn't put the 770 into wrong USB port
of the hub (stupid me...)

The Y-cable I have has two A-type plugs,
one of them for power only,
and one Mini-B plug, which goes into the Nokia.
But the hub input port has a Mini-B slot, too.
Solution: Gender changer A-female to A-female,
and another A-male to Mini-B male cable,
where the Mini-B plug goes into the hub input port...

Much cabling for one USB keyboard, isn't it?
However it works without slicing a single USB cable;-)


I still wonder why Nokia made it that difficult to use a wired keyboard with the 770...

short answer: to force people to use an external usb power supply.

I wish Nokia made a powered USB hub accessory made specifically for the 770. Things would be so much easier not having to work thru a myraid of cables.
