Hallo!
I'm having a trouble with the 2 frontal USB connectors in my peg2 G3.
In the manual is stated that the Pegasos has 4 USB ports. Ok, I see the 2 ports in the motherboard but in the front connector (where the led cabels etc. are attached) it seems reading the manual that there is only 1 usb connector. I tried to connect this to one of the USB ports of my Micro-ATX case but it doesn't work at all.
I can say that looking on USB setting, there are only 2 USB controllers detected by Poseidon.
Could you please let me know if I'm doing something wrong?
Thanx a lot in advance!

Well seesm you did it right, just check the cables again (4 lines, dont mess them up!) and be sure the usb device you plug in works (test it with one of the connectors of the backplate).
Well the four ports are:

2 connectors at the backplate
1 on the mobo
1 at the agp

the one on the agp is only accessable with a gfx card providing an usb connector.

the two devices listed by Poseidon aren't the ports they are two devices provided by the controller, the root hubs. each root hub provides two ports.

OOps, my fault connecting the cable...
now the frontal connector is working!!!

Thank you very much Zylesea!!

hmm, well, i'm glad there is a thread about this!
is there any pics on exactly where the wires get connected?

I have ALOT of wires coming out of the front USB ports and they are connected to nothing!

and the rear USB ports don't seem to work at all.

I'm completely unfamiliar with PPC hardware (I was given this Pre-April system) and I'd like to do a little research before I start touching anything. I just don't want to blow anything up!


anyway, this just can't be a problem that only I have! The PDF file that comes with MOS1.4 has a pic of something but no real explaination of where the wires go.
let's just say it doen't leave me with any confidence.
If I can find enough info I'll be happy to make a FAQ so that there is a final and useful answer that everyone can get to and have a solution.

Trust me, I looked at the brief discussion here and it all looks like chinese to me.

With my AMiga I installed HD's, accelerators, memory, video cards, DCTV, JAZ and Syquest drives, CD drive, and I forget what else. But I generally had some sort of docs to follow. And it worked. But i'm no techy.

Once i understand someting I can generally explain it, however, so all I need is a little help.

It is simpler than you think. In the MorphOS 1.4.2 "Docs" directory there is a file named FrontPanel.pdf. This is an image of the on-board connector where most connections coming from the front panel of the case should go. Here we are interested to the USB connections, that in the figure are marked as:

VCC-USB
DM1
DP1
GND-USB

There are only 4 leads in the Universal Serial Bus connections. 2 leads carry the power supply (VCC-USB: positive voltage, and GND-USB: ground) and two leads carry the serial digital signal (DM1: digital negative, and DP1: digital positive).

Now watch the cables coming from the front panel of the computer case. Usually there are 8 leads caming from the two front USB ports. 4 should not be used (and the relevant USB port will be "dead"), and 4 should be connected to the board connector. They are marked in different but similar ways by various manufacturers. In my computer case they were marked POWER, D2+, D2-, GROUND, and again POWER, D3+, D3-, GROUND (2 and 3 here stand respectively for USB port 2 and USB port 3; port 0 and port 1 are inplicitly assigned the rear USB slots). Here POWER means positive power supply, D2- means digital negative (port 2), D2+ means digital positive (port 2), GROUND is obvious; and then these labels are replicated for the leads coming from port 3.

I hope you realize that in this case POWER has to be connected to VCC-USB, D2- to DM1, D2+ to DP1, and GROUND to GND-USB. And I hope you will be able to realize the connection to do if your leads are named in a slightly different way.

Please note that you do the connections at your own risk! If you have even a very small doubt, do not connect and call an expert!

Cheers.

Well first a question what makes you think the usb ports at the
backplate do not work? Best is to boot into Ambient open "settings ->
system settings" Then cycle on the left hand menu through to "usb".

Then you will see a window which shows you some information about the
present hardware. If the uhciusb.devices unit 0 and unit
1 are *not* listet, then it really seems somethig is weird with your
setup (hw crash of the usb or some hard mess with the poseidon (usb
stack) files. Best to avoid complications when checking the above
procedure is to boot off a CD - then poseidon *should* be working
correctly...

If everything is fine so far just go at the usb settings to the topic
"devices" crawl under the desk and plug in an usb device of your
choiceAt the console at the bottom of the usb settings window ther
shoud appear some messages telling you the result of the attempt to
mount the just pluged in device. At the list above your device should
be added under both hub antries.


Other issue - Cabling the internal usb connector:

Att he mobo there are for panels near the memory slots present. two of
them (the both neigbouring to th ecpu slot) are for IDE, then there
are two more left one for the floppy (well noone needs this..) and one
26 pin connector (just neighbouring the memory slot) for multiple
purpose. If you look at that connector there are two rows of pins. If
you look to the mobo that the front panel of the Peg (i.e. the
external ports like parallel, usb, ps/2) are on your left hand you
have to count the pins of that connector from the top on. The
right pin row starts from the top with one not used pin and then
4 pins for usb connectivity starting with (counting from top
downwards!!)

- gnd
- usb signal D+
- usb signal D-
- usb 5 volts

your case should offer four cables per usb connector on the front.
These cables should be taged somehow like usb1 gnd, usb1 D+, usb1 D-,
usb1 5V and the same set with usb2 gnd, usb2 D-, ... Choose the 4
cables according to one connector and plug them into the connector.
Take care that you dont mess up one of the cables, your Peg would not
thank you that!

Again all pins on the right row of the connector
1 - not used
2 - usb gnd
3 - usb D+
4 - usb D-
5 - usb 5V
6 - KCLK
7 - KDATA
8 - -SCLK
9 - SDATA
10 - HDD LED +
11 - Power LED +
12 - Reset (pin A)
13 - Power on (pin A)

The left row is

1 - PC speaker Pin A
2 - not used
3 - not used
4 - PC speaker Pin B
5 - IRDA power supply
6 - IRDa RX2
7 - IRDA RX
8 - IRDA GND
9 - IRDA TX
10 - HDD LED -
11 - Power LED -
12 - Reset pin B
13 - power on pin B

/me hopes this clarifies some things up...

Quote:beause neither my zip drive nor my camera are detected. and BOTH have been used successfully on other pegs.

as soon as it was available i installed the latest posidon (2.2, is the latest, i believe). and while it appeared that certain things were "better" (mostly less error messages), i still didn't have a working USB port.
anyway, i'm unfamiliar with posidon as i never had a PPC card in an amiga.

thanks for both your help and I'm making a copy of these instructions. when I get a spare moment, I'll see if i can make any sense of it all and look at the insides of this peg.

It doesn't take a lot to check the usb ports: boot off the MOS 1.4 CD, just open the usb settings ad have a look if the root hubs are listed or not. If they are everything's fine, if not then there's something wrong.
This check requires about one minute...

Hmmm,

I too was puzzled by the differences between the marks on the usb-cables and the description for the internal usb-pins. After reading this thread I connected the cables to the right pins and booted my Peg. Alas, Poseidon showed only the two onboard hubs. I checked the history, and there was an error message, saying that "uhciusb.device unit 2 failed device/unit failed to open (-1)". Any ideas?

Quote:
Do you get any error messages after connecting any USB device? Check the log at the bottom of USB prefs...

Things, that could be wrong:
1)Device might need you to set "Translate CMD6->CMD10" in Poseidon prefs

2)You haven't installed fat95 (The device works, but FAT partitions cannot be mounted)
