Can't start io-usb

Bill_Caroselli1 · July 21, 2004, 8:43pm

Whenever I try to start io-usb my system freezes. By freezes I mean that
I can no longer type into a pterm, move the mouse or change consoles.

I have tried these two command lines so far:
io-usb -dehci -duhci
and
io-usb -duhci

I was logged in as root at the time and I’m running 6.3 PE.
What can I do to get a USB stack?
Ultimately I want to support one of these USB flash drives.

From the pci utility my system has (4) of these:

Is legacy support enabled in the BIOS ?
Try disabling it to see if this helps.

This system is a Dell PowerStation 350.

I went into the BIOS. The only USB related options were:
USB Emulation - ON
USB Controller - ON

Since I had already tried many io-usb options in this state, and because
of your comment below, which I realize doesn’t really apply here, I turned
off USB Emulation in the BIOS.

I rebooted QNX and this time stayed in text mode. i.e. photon was not
loaded.

When I ran “io-usb -duhci -dehci” I saw the following message which I did
NOT see when run from a pterm:
DLL Error Library cannot be found
Failed - io_usb_dlopen
unable to load dll devu_echi

When I rebooted I ran just “io-usb -duhci” from the text console I saw no
error messages, however, in both cases the system froze about 1 second
after entering the command.

And then just for ships and grins I tried “io-usb -dohci”. I know I don’t
have one of these type of controllers but what the hell, right? There was
no error message and the system did not freeze either. Unfortunately,
neither did the USB stack work.

What can I try next?

OK. USB Emulation is still off.

HV > Are there any usb devices plugged in when you start the drivers ?

There weren’t the first few times I tried to do this. But I just retried
with my USB flash drive plugged in. It still freezes.

BTW, I tried the flash drive in another QNX system and it does work great.
So I assume that I’m loading the drivers correctly.

I will try to boot this system in Windows and verify that the USB ports
are not defective.

LOL. Sorry, no. I cut and pasted the example from the io-usb helpviewer
page. I guess I just typoed as I typed in the message.

This brnigs up an interesting point. The pci utility says I have:
UHCI
UHCI
EHCI
UHCI
UHCI
EHCI
in that order. But there are 6 USB ports out the back of the CPU and two
out the front of the CPU and I don’t know which port actually goes to which controller.

Does it matter which port I plug into? My device is only a Full-Speed.
If I only load the UHCI driver will it support all 6 ports in UHCI mode?

Thanks for trying.

Yes, the emulation option is what I was asking you to turn off; to see if
the BIOS to driver handoff is somehow not working correctly on this
machine.

Are there any usb devices plugged in when you start the drivers ?

I rebooted QNX and this time stayed in text mode. i.e. photon was not
loaded.

When I ran “io-usb -duhci -dehci” I saw the following message which I did
NOT see when run from a pterm:

^^^^^^^

could you have type in “-d echi” instead of “-d ehci” when starting the

error messages, however, in both cases the system froze about 1 second
after entering the command.

maybe try attaching to 1 of the chips or 1 of each type chips to see what
happens.
Leave emulation mode off in the BIOS for now.

io-usb -dehci pindex=0 -duhci pindex=0 will connect to the first chip of
each type
or
io-usb -dehci pindex=1 -duhci pindex=1 would connect to the second chip of
each type

And then just for ships and grins I tried “io-usb -dohci”. I know I don’t
have one of these type of controllers but what the hell, right? There was
no error message and the system did not freeze either. Unfortunately,
neither did the USB stack work.

Yes you dont have any OHCI chips.

What can I try next?

I’ll see if I can find a machine with this chipset to see
if I can reproduce it here.

Well, everything works under Windows-XP. I can look in the windows device

Let me get a clarification on this. If I only load:
io-usb -d uhci
will that support all 6 ports? So that it doesn’t matter which port I’m
plugged into?

Or are you saying that if I only load one uhci device (i.e. one -d uhci)
then it will only support the first two hardware ports found?

Yes.

It would only matter if you started the driver using pindex=# for the DLL
and
didn’t tell the driver to use all of the chips. The UHCI chipset is limited
to controlling
2 ports. The EHCI driver takes control of the ports when loaded and routes
them
to the UHCI chipset if a low/full speed device is connected. If no EHCI
driver is loaded,
then by default they are automically routed to one of the UHCI chips.

Well, everything works under Windows-XP. I can look in the windows device
manager if there is any useful information.

I tried the drivers on a machine here that has the same USB chipset and they
work fine here. The machine I tried here has 4 UHCI chips and 1 EHCI chip.

Can you post the full output from pci -vvvvvv.

Let me get a clarification on this. If I only load:
io-usb -d uhci
will that support all 6 ports? So that it doesn’t matter which port I’m
plugged into?

Yes, the DLL will attach to each of the UHCI chips.

Or are you saying that if I only load one uhci device (i.e. one -d uhci)
then it will only support the first two hardware ports found?

No I was saying that if you started the driver
io-usb -duhci all of the ports would work
io-usb -d uhci pindex=0 2 ports on the first chip would work
io-usb -d uhci pindex=0,pindex=1 4 ports would work 2 for each chip.

So the EHCI port would also work in UHCI mode?

Sure. It is copied below.

Let me get a clarification on this. If I only load:
io-usb -d uhci
will that support all 6 ports? So that it doesn’t matter which port
I’m
plugged into?

HV > Yes, the DLL will attach to each of the UHCI chips.

Or are you saying that if I only load one uhci device (i.e. one -d
uhci)
then it will only support the first two hardware ports found?

HV > No I was saying that if you started the driver
HV > io-usb -duhci all of the ports would work

So the EHCI port would also work in UHCI mode?

UHCI handles full/low speed devices. EHCI handles high speed
devices only. If you have both EHCI and UHCI drivers loaded, the
EHCI driver initial controls the ports. When a device is plugged in
it checks to see if it is a full/low speed or a high speed. If it is high
speed then it hangs onto control of the port, otherwise it is
switched/routed to a UHCI chip.

OK.

Here is pci -vvv ===========================

Did we learn anything from the complete pci output?

What do I try next?

Personally I’m not a big fan of USB. I think it is a technology that is
still about where PCI v1.0 was. I’m not talking about the QNX
implamentation. I mean all USB. It seems that if you have multiple
devices all working at the same time then something ultimately locks up.

But, hopefully we haven’t forgotten about this.
I really need to get this thing working.

The only difference betweeen the USB chipset you have and the one I tried is
the Reivsion ID. The one I tried it on has a Rev ID of 0x81, yours is 0x50.
Most of the other chips on the Motherboard I tried were from VIA.
I also tried a PCI add-on card I have that has the VIA VT83C572 UHCI chip
on it and it works fine too( rev id 0x4).

It looks like this USB chipset should work fine to me. There must something
else going
on related to HW/BIOS/IRQ.

What do I try next?
Not sure what else to try other than playing with BIOS settings( Make sure

power management is off )
It would be nice if I had hardware here that could reproduce the problem.
If you’re really desperate you
could put an add-on card in.
