Cross posted to Ubuntu Forums

I have a i.MX51 (arm) based system. Sharp PC-Z1 and I am
trying to get a USB Dongle WIFI working.
(The internal one died)

The usb stick is a RT2870 device and the system does have
/lib/firmware/rt2870.bin

It also has /usr/src/linux-headers-2.6.28-15-araneo/drivers/staging/rt2870

Makefile and Kconfig

but that is all. no rt2870sta.ko etc

Is it possible I have enough on the system to complete the generation of the needed file to enable this device?

It's Ubuntu 9.04

Can the mini-USB port be used as a networking port?

Maybe it is a more basic question of making my PC's USB port act like a Ethernet Device (Network Device)

I already can use my cell phone as an Internet connection on the full size USB, I'd like to be able to use the same cable (USB - mini-USB) to my PC to do the same thing.

Once you have the NetWalker open (like in my other post to change battery / LCD) here are some pictures of the Keyboard.

If you remove the keyboard



There are four springs that keep it floating



They will likely all pop out, I was lucky one stayed in.
They are tapered and the narrow end goes down.



Like so



The battery cover also hold down the top edge of the keyboard, so it is very likely it will come off while you are handling it.

So best to remove it and save the springs so they do not get lost!

Put the keyboard back on and then put the battery cover on right away.

The Screw plugs come in two sizes. The 2 bigger ones have a "3" in them



More as I learn...

I figured I would post these disassembly steps for anyone else who needs to replace a cracked screen sad.gif

Read entire post before attempting on a real unit *** NOT COMPLETE YET ***

The only other info I found was in Japanese.

Remove the small plugs that cover the screws.
There are two sizes, the ones over Big(2) have a "3" in them, see a picture in my other post.

The two big ones are feet, not screw covers.

If you are only replacing the battery or LCD you only need to remove the Big (2) and Long (2) screws.



The screw heads are very small, Phillips size 00 (PH00)



Remove the Battery Cover, lift from the top.



This will expose the battery, which can come out of the channel, but is attached with a group of wires.



Since my battery is fine, I did not look for a connector or open the covering.
(Call me chicken, but I have enough problems right now)

To open the upper case there are two screws at the bottom next to the hinge/battery cover.



To be able to reach them with a screwdriver, close the lid most of the way, with the battery hanging down.



Here you can see the Strange screw head, along with the wires to the battery.



At this point I am stuck, until I find the proper screwdriver for this. ohmy.gif

Ok Wikipeadia says it is a Tri-Wing or Triangular Slotted blade.. But as with the PH00 is it SMALL
I found a small screwdriver set on ebay where they call it a Y Screwdriver. They mention other electronics,
like GBA etc.

We'll see if it fits when I get them...

I will update this when I learn more...

My Netalker slid off my desk and dropped on it's corner...

It still works, but I am sure the touch screen doesn't

It is cracked in many places.

The LCD and case membrane are fine...

See the attached image for the results...
