Ok, I give up... How do I mount my 1Gb PNY Attache USB??? I followed the how to and this is as far as I get...

You need to load the sd_mod module (or build it into the kernel - it's "SCSI disk support" in menuconfig), else SCSI devices are detected but do not have device nodes affected to them. With sd_mod loaded, you should have one more line in dmesg saying that sd 0:0:0:0 is bound to /dev/sda. Then just mount the device it gives you.

CaptnKlink,

A few things to look at.
You appear to have USB 2.0 and USB 1.1 hardware supported via EHCI-HCD and OHCI-HCD.
You don't need the UHCI-HCD driver at all but it appears to be loaded. This is known to break things sometimes.

Your PNY 1Gb stick is USB 2.0 capable - You will hate it at USB 1.1 speeds, it may not fall back properly either. Many devices don't.

Sort your USB devices into two groups, USB 2 in one and USB1.x in the other. USB root hubs can do both standards but not at the same time.
They will revert to USB 1.x if a mix of devices is connected.

You will see your PNY drive attached to the USB 2 driver when thats sorted.

USB mas storage appears as SCSI, so your kernel needs to support SCSI disks, it will be vfat by defauly, so you need vfat support too..
Then the mount is

Code: Select all

mount /dev/sdX1 /mout/point -t vfat

where X is the letter assigned to your device.

I enabled SCSI disk support with MAKE MENUCONFIG

I also enabled both USB drivers because I knew I had both types, thinking about this now and 2.0 backward compatibility - I going to go back and only enable 2.0..?

VFAT is enabled.

CaptnKlink,

Not quite, you need EHCI-HCD and OHCI-HCD but you appear to have UHCI-HCD enabled
Turn off UHCI-HCD.

Something bad happened on re-boot so I figured it was easier to just start over and re-format and re-install...

So here I am again back at trying to get my USB memory stick going again.
I edited my kernel with make menuconfig, enabled EHCI-HCD and OHCI-HCD. Re-compiled the kernel and re-booted.
Now this is what I get:

Code: Select all

proteus dev # dmesg | grep USB
ehci_hcd 0000:02:0e.2: new USB bus registered, assigned bus number 1
ehci_hcd 0000:02:0e.2: USB 2.0 started, EHCI 0.95, driver 10 Dec 2004
hub 1-0:1.0: USB hub found
usb 1-1: new high speed USB device using ehci_hcd and address 2
drivers/usb/input/hid-core.c: v2.6:USB HID core driver
Initializing USB Mass Storage driver...
scsi0 : SCSI emulation for USB Mass Storage devices
USB Mass Storage support registered.
USB Universal Host Controller Interface driver v2.3
ohci_hcd: 2005 April 22 USB 1.1 'Open' Host Controller (OHCI) Driver (PCI)
ohci_hcd 0000:02:0e.0: new USB bus registered, assigned bus number 2
hub 2-0:1.0: USB hub found
ohci_hcd 0000:02:0e.1: new USB bus registered, assigned bus number 3
hub 3-0:1.0: USB hub found
  Vendor:           Model: USB Flash Memory  Rev: 1.00
usb 1-1: USB disconnect, address 2
usb 2-1: new low speed USB device using ohci_hcd and address 2
input: USB HID v1.00 Mouse [Logitech Inc. iFeel Mouse   ] on usb-0000:02:0e.0-1
usb 1-3: new high speed USB device using ehci_hcd and address 4
scsi1 : SCSI emulation for USB Mass Storage devices
  Vendor:           Model: USB Flash Memory  Rev: 1.00

The two code outputs look exactly the same to me so I'm confused. What do I need to do next to mount my USB drive?

From following the online guide (http://gentoo.org/doc/en/usb-guide.xml) I should be able to type mount /dev/sda1 /mnt/usb but that doesn't work...

Note: I don't know anything about Linux (yet) but it's only been a week. I had working Fedora and CentOS systems going so far but I like Gentoo so much better!!! My hard-drive is probally going to explode soon with all the times I've re-formatted it... So thanks for all the help

CaptnKlink,

Going through your dmesg snippet ...

Code: Select all

ehci_hcd 0000:02:0e.2: new USB bus registered, assigned bus number 1
ehci_hcd 0000:02:0e.2: USB 2.0 started, EHCI 0.95, driver 10 Dec 2004

is good, it shows your USB 2.0 hardware is alive and well.

Code: Select all

Initializing USB Mass Storage driver...
scsi0 : SCSI emulation for USB Mass Storage devices
USB Mass Storage support registered.

is good too, your USB Storage driver is loaded and showing off USB Storage devices as SCSI.

Code: Select all

USB Universal Host Controller Interface driver v2.3

is bad. You don't have UHCI USB 1.x root hubs and loading both UHCI and OHCI drivers can prevent proper operation of USB 1.x altogether.

Code: Select all

usb 1-3: new high speed USB device using ehci_hcd and address 4
scsi1 : SCSI emulation for USB Mass Storage devices
  Vendor:           Model: USB Flash Memory  Rev: 1.00

suggests you have two USB mass storage devices attached, since you now have scsi0 and scsi1.

It looks like you are missing the top level SCSI Disk driver from your kernel, or if its a module, its not loaded. Try

Code: Select all

modprobe sd_mod

to attempt to load the module. In the kernel configuration, its under Device Drivers -> SCSI device support -> SCSI device support where you need legacy /proc/scsi/ support and SCSI disk support.

I must be missing a step somewhere or doing something wrong because I keep getting the same results.

I did notice that during boot, UHCI is being loaded along with EHCI and OHCI. The screen buzzes past too fast for me to see what it's doing...

I have done the following:
emerge --sync
emerge --update portage (because --sync told me there was a new portage availible)
emerge --update genkernel
emerge --update gentoo-sources
etc-update
genkernel --bootsplash --install --no-clean --menuconfig all

I have enabled OHCI and EHCI, SCSI disk support is on as well. After exiting menuconfig I did have several time sync errors if that makes a difference.

?????

CaptnKlink,

I'm not sure what you mean by time sync errors?
Like ... file has a timestamp 3e9 seconds in the future, or some othernumber of seconds ?

That can confuse make, becase it compares the timestamps on the source files and binary files to determine if
the binaries need to be remade. If the sources are newer, then they do. So timestamps are important. Errors can provent things being built that need to be built.

CaptnKlink · Post by **CaptnKlink** » Mon May 08, 2006 6:28 pm

NeddySeagoon,

Yes. That is the error. Something was done in the future... I read somewhere about using ?--no_time_check? to surpress the errors will this cause any harm?

Let me ask you this question...
My original GRUB bootloader calls out kernel 2.15 r-5 (or something like that) but my new compiled kernel is 2.16 r-6. I have tried to edit the bootloader from GNOME ->Desktop->?administration?->Boot. I can copy and make a new version and even edit the original but everytime I open this command box the original gets re-created and set to default. If I open the box 10 times I get 10 copies of the original all set to default. Probally a bug... Anyhoo, my question: How do I edit my GRUB bootloader directly?

Secondly, if I edit the GRUB bootloader at startup to use my new kernel I get a Panic Error, can't find RAM0. They are the same settings as my old bootloader but I think ?SADA? isn't loaded in my kernel. Where is it and what is this new INTRD thingy for???

I'd like to thank you for taking the time to help me through this

I'm at work and can't remember the correct syntax so that is why somethings are inside question marks...

problem solved.

Post by **NeddySeagoon** » Wed May 10, 2006 4:35 pm

CaptnKlink,

Its go to know you solved your problem - please post your solution so others can benefit.

Your initrd is a root filesystem in a file. It is attached to /dev/ram0 for the kernel to use at boot time.
It typically holds any modules needed to mount the real root filesystem and any third party kernel modules needed early in the boot process.

My solution...

I changed to a different distribution. *dough* Not Redhat, Fedora or CentOS, not Debian.

I'm now running openSuSE.
My ACPI is supported and my USB drive mounted instantly. I can use my computer again instead of spending countless hours stumbling through what isn't making it work.

Perhaps when I learn more about Linux and how it works I'll load Gentoo again. I picked up a book "Running Linux, 5th edition" I think it will be a good start on the learning path.

Post by **NeddySeagoon** » Wed May 10, 2006 7:52 pm

CaptnKlink,

Thats as valid a solution as any other. An OS is a tool to do a job and should be selected on that basis.
I would encorage you to leave a corner (do HDDs have corners?) of your HDD for a Gentoo install if you want to learn.
Not for everyday mission critical use but as a learning resource.

Good luck with your Linux experiance, whichever distro you choose.
