Soldering onto the usb ports

[21q]

With the project I'm doing I need to solder directely onto the usb ports. I get power just fine but I'm just not getting data.
Now I am trying to hook it up to the pc by using this usb in the pciture. Since the ps2 is powered down it theoretically should work as a normal usb device. But I simply don't get data access.

Am I doing something wrong or is it simply not possible?

There is a possibility that your post make little to no sense.

You have your wires soldered on backwards.
Flip the order. Take a look at the top right diagram. USB pinout and wiring @ pinouts.ru
Also go easy on the solder. Looks like you got a bunch of it on some of your pins.

I get power though? even so it could still be backwards? This is on the underside of the ps2 slim.

Well if its on the underside then you appear to have it wired correctly. However I can't see what your wires are going to. Could you give more detail and show where the wires are connected? I was gonna talk about differential signaling and noise canceling but for a project this small you might be able to skirt by.

The other side goes to a sata adapter. http://i84.photobucket.com/albums/k6...-24-10_198.jpg

On this side there is no soldering, so I shouldn't have to worry about it. Since I already desoldered the wires I think I'll twist the data wires before I try it again.

Went and tested the adapter by wiring on a usb head. It still works so I know thats not it.

So you're hard wiring a hdd to one of the usb ports of your ps2?
Never owned a ps2 but that sounds like an interesting project.

Anyway, so you've verified that your sata adapter works correctly by soldering a male connector to the end of your cable?
If you can read and write to the disk via a pc, then your cable setup should be fine. Is the hard drive formatted for use in the ps2?

Also, I wouldn't assume you're actually feeding 5V through the cable via your usb port when the system is powered down.
You say you get power however, does this mean your hdd is spinning?

I`ve done that about a hundred of times, i dont understand what s your problem, my english is bad, explain pease, i can help you.

The laser died so I thought I'd try and make an internal hdd. Since this is the slim it's the only option.

Yeah I verified it works still. I know the ps2 needs the hdd to be formatted as fat32, but that shouldn't make a difference right now since im only using the usb port to connect to my pc.

The drive does spin. The ps2 uses usb 1.1, but as far as I know there was only a difference in data transfer rates, not power.
Maybe the wires just aren't making good contact? The led lights show that the computer is trying to access the drive, but then it just stops.

Ah I thought this would be much simpler.

You need atleast 700mA of current coming from your usb port in order to get this drive to work. A usb (1.x to 2.0) will only support up to
500mA of current draw. Unless your sata adapter has a boost converter (increase the current and lower the voltage), you're probably not going to see this work.
