Enable USB?


I have Linux running on an embedded system. It is running kernel 2.4.21-1. I have plugged in two different pen/thumb/jump drives and neither one is recognized when plugged in before bootup or after bootup. Is there a way to tell if USB is installed/enabled? If it's not, can someone give me a step by step on how to enable it. Any instructions must be command line because display is done via the serial port. Thanks for any help!

Have you tried "lsmod" to list modules?
Sorry if it's not applicable to that system...

Check the output of dmesg and see if there is any relevant output when you plug a USB device in. lsmod is a good idea also but I don't know the names of the 2.4 USB modules so I can't tell you what to look for.

Nope, but since USB is obviously not working I'm going to suggest 'insmod usbcore' and see if you have any luck.

Quite frankly, what is an embedded system?

There are two different USB host controllers for USB 1.0/1.1, and one for USB 2.0.

Rather than explain it myself, let me post from my 2.6.17 kernel .config file:
Code:
OHCI HCD support (USB_OHCI_HCD)

The Open Host Controller Interface (OHCI) is a standard for accessing
USB 1.1 host controller hardware. It does more in hardware than Intel's
UHCI specification. If your USB host controller follows the OHCI spec,
say Y. On most non-x86 systems, and on x86 hardware that's not using a
USB controller from Intel or VIA, this is appropriate. If your host
controller doesn't use PCI, this is probably appropriate. For a PCI
based system where you're not sure, the "lspci -v" entry will list the
right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.

To compile this driver as a module, choose M here: the
module will be called ohci-hcd.

UHCI HCD (most Intel and VIA) support (USB_UHCI_HCD)

The Universal Host Controller Interface is a standard by Intel for
accessing the USB hardware in the PC (which is also called the USB
host controller). If your USB host controller conforms to this
standard, you may want to say Y, but see below. All recent boards
with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
i810, i820) conform to this standard. Also all VIA PCI chipsets
(like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
133). If unsure, say Y.

To compile this driver as a module, choose M here: the
module will be called uhci-hcd.

EHCI HCD (USB 2.0) support (USB_EHCI_HCD)

The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
"high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
If your USB host controller supports USB 2.0, you will likely want to
configure this Host Controller Driver. At the time of this writing, 
the primary implementation of EHCI is a chip from NEC, widely available
in add-on PCI cards, but implementations are in the works from other 
vendors including Intel and Philips. Motherboard support is appearing.

EHCI controllers are packaged with "companion" host controllers (OHCI
or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports
will connect to EHCI if the device is high speed, otherwise they
connect to a companion controller. If you configure EHCI, you should
probably configure the OHCI (for NEC and some other vendors) USB Host
Controller Driver or UHCI (for Via motherboards) Host Controller
Driver too.

You may want to read <file:Documentation/usb/ehci.txt>.
So on this computer:
Code:
root@silas:~# lspci -v

        Memory at fdf00000 (32-bit, non-prefetchable) [size=256]

Hope this somehow helps you...

The system is a MIP405 PowerPC which is a computer that is contained on a 4in. x 4in. board. The board is manufactured by MPL ( www.mpl.ch ). The user manual says that there are 2 USB 1.0 ports, does knowing this change anything?

Interesting gadget. I read "Also a Linux distribution is available for the MIP405."
Are you running that? If so I'd expect it to be configured right. Do they offer support?

Issue as root "lspci -v" and post it all in here, please. Another thing I see is
"Southbridge PIIX4E 82371 EB" -- which is Intel. If so, you need "USB_UHCI_HCD".

Plug in the device and then issue "dmesg | tail" and you should see it. Some output such as this:
Code:
mingdao@silas:~/kernel$ dmesg | tail
sdc: Mode Sense: 03 00 00 00

I am running the version of Linux that came with the board, so I imagine that is the distribution you are speaking of. It appears that they don't have it configure correctly.

I tried looking at the /usr/src/linux-2.4.21-1-ppc/.config file, and this line is commented out: "# CONFIG_USB_EHCI_HCD is not set"

The mpl support told me to try "modprobe usb-ohci", but the module could not be found, and I discovered it is commented out in the .config file as well. I'm stilling waiting to hear back from them on what they suggest next.

Here are the commands you wanted:

EHCI is for USB 2.0, and the docs state the board has USB 1.1, so it's not needed.

Strange that "lspci -v" gives no more data...

What is the output of "cat /usr/src/linux-2.4.21-1-ppc/.config | grep -i usb" ?

This is beyond my knowledge, but if it were me, I'd try to compile a new kernel.
And I wouldn't bother with a 2.4 kernel -- get the latest stable 2.6 kernel. You didn't include your location in your UserCP, so I gave you an US ftp mirror.

I have posted two simple kernel rebuild HOW-TOs in threads here:
Rebuild 2.6 kernel under /home
Rebuild 2.6 kernel under /usr/src/

The only document I can get to on the internet is:
http://72.14.235.104/linux?q=cache:B...n&ct=clnk&cd=2
which isn't the hit I got at Google <Linux>, but it's cached page. I read there:
Quote:
USB Support: At the moment only the UHCI host controller is supported (PIP405, MIP405, MPC5200); define CONFIG_USB_UHCI to enable it. define CONFIG_USB_KEYBOARD to enable the USB Keyboard and define CONFIG_USB_STORAGE to enable the USB storage devices.
Please keep us updated, especially with what your tech support says.

I've tried to compile a new kernel with the modules I want in it, but I did not really know what I was doing. Appearantly the steps are similar but not excatly the same as a regular box. To be honest, I've only been using Linux for a few months so all of this is a little bit over my head. The only reason I am working on this is because nobody else that I am working with has any experience with Linux. This website ( http://www.mpl.ch/t2722.html ) gives information on compiling a kernel for the MIP405, but I'm still not quite sure how to do it. I think I set the .config file how I want then run "make dep" then "make clean" then "make uImage" but I'm not sure after that. When I originally installed the OS, the file system went on /dev/hda5 and a copy of the kernel image went into the the /boot directory. I then had to do something to load the kernel onto /dev/hda1 using a command like "dd if=/boot/(don't remember the file name) of=/dev/hda1". I can't find the manual for doing this online and the paper version is back in the office. If you could help me get a step by step, I would appreciate it.

I also don't know how to download a newer version of the kernel because I am not use to not having a gui to work from. I could download the kernel and burn it to a cd and hook a cd drive up to the board or do ssh to a machine that has gui and do "scp", but I'm sure there is a way to do it via the command line since I have internet on the MIP405.

I can ssh into the board from my home, so if you respond tonight, I will try any of your suggestions

Thanks for ALL of your help!

I briefly read the kernel instructions in your link, and don't want to comment too much. No experience with PPC, and I'd not want to cause you to hose that system.

If you have the program wget, an easy way to get the kernel is to issue "wget ftp://ftp.us.kernel.org/pub/linux/kernel/v2.6/linux-2.6.17.tar.bz2" or substitute the path to the kernel you desire. Previously I was thinking of using a 2.6 kernel, rather than a 2.4. You build them quite differently, and IMO Kwan Lowe has an excellent Kernel Rebuild Guide.

If you're willing to take some risk, perhaps following that guide and adapting from an i386 architecture to PPC would work. Meaning, where Kwan has i386 you need to think ppc.

I believe the dd command would be "dd if=/boot/<kernel-image-name> of=/dev/hda1" if that's all there was. You can "ls -lh /boot/" after you install the kernel to see it's name. Never used uImage, which probably has to do with that Universal Bootloader .

Have you checked the resources here -> http://penguinppc.org/about/community.php ? Might be able to even chat on IRC with a PPC guru now.

Tech support told me that USB support is unstable in this kernel and I should compile a new one using kernel 2.4.31 and the patch from ftp://ftp.mpl.ch/pub/temp/linux-2.4....p405.patch.bz2 . I downloaded the kernel and patch onto another linux machine because wget was unrecognized by the MIP405. I transfered the files over ssh to the board and untared the kernel to /usr/src then used "cp linux-2.4.31-pip405mip405.patch /usr/src/linux/.config". Then I issued the command "make dep uImage modules" as the instructions for compiling stated. After answering an hour worth of questions (which I didn't completely know the answers to), the kernel started to compile.

I've gotten a few errors, but I think I've figured them out. The instructions for compiling say to use a cross-compiler. Is that so you can compile on another computer that is faster? The processor on the MIP405 is only 266MHz I think. How do you get/make a cross-compiler?

Back to trying to compile!

I need to read your post more carefully. But in order to keep from having to answer so many questions, you could have first copied your present kernel's .config file to the new kernel source directory, like this:
Code:
cp /usr/src/linux-2.4.21-1-ppc/.config /usr/src/linux-2.4.31/
so that your sources start our with the old .config file.

Next you would run "make oldconfig" and answer any questions that came up. You can hit the ? at each one to see what it's about, and if you don't know, it's usually okay to enter for the default. If you're not comfortable with that, you could always say N to new questions.

Then you would run "make menuconfig" and just change the USB or whatever else support said to change. Then you could patch and continue with "make mrproper" or whatever their next step was.

If you got through that compile okay, and have both kernels to boot, then just go ahead and see how it works. But if you have any problems, it's safe enough to start over.

If you do start over, there are some instructions you'll want before you do...
