1  General Category / General Discussion / Re: Missing usbserial kernel module and modules.conf on: July 17, 2010, 04:34:46 PM
tbm: There is nothing in /lib/modules at all.

I have not installed any other Linux yet. It is the stock version coming with vendor.

Where do I get the debian version for this box?

Can I install the missing kernel modules and required stuff with apt-get or aptitude?

What are the steps to get a debian onto a separate SD card?
(I don't like to kill the running version)

I also got the live CD for sheeva development that is needed to compile the usbserial.ko, but it seems that it didn't contain libc headers. So would it possible to compile the kernel without the libc? (http://plugcomputer.org/plugforum/index.php?topic=434.0)

My helloworld, including stdio.h won't compile. Then I installed the unixODBC development libraries and within it seems to install the x86 toolchain.
So it either wasn't a cross compiler suite or I got it managed to replace it :-)

What is the best way to get usbserial running, but also get started with cross compiling?
I want to port my project to arm :-)

I have the vendors product CD and it contains the toolchain. Is it the only source?

I got the usb-modeswitch working and I can switch my USB Storage into the Modem mode. But then I tried modprobe usbserial vendor=0x12345 device=0x67890 with no luck. Here is my output:

root@debian:~# modprobe usbserial vendor=0x1c9e product=0x9603
FATAL: Could not load /lib/modules/ No such file or directory

Then I have had a look into the /lib/modules directory and see nothing. What packages must I install to A) get lsusb and B) get usbserial to work?

I understand what I have to do. But the page explains to use usb-modeswith which should be installed via apt-get install usb-modeswitch.
This doesn't work even if I do a apt-get update beforehand.

Where can I get the package and how do I tell apt-get optionally the source where it comes from?

I think, the device will be supported by Linux, but I need a starting point about the driver or setup.

Has anyone any experiences with this device?

Here is a german posting related to the same hardware (and it's name) but O2: http://www.linux-club.de/viewtopic.php?f=27&t=105622&start=0

this looks interesting for the new guruplug server plus: http://www.elv.de/USB-eSATA-Festplatten-Docking-Clone-Station/x.aspx/cid_74/detail_10/detail2_28035/b_1

Are there similar products?

6  Hardware and U-Boot firmware / Hardware / Still trouble getting my USB HDD working automatically on: February 28, 2010, 05:11:53 AM

after some tries I have got running my USB HDD after adding a wait script to let the kernel detect the HDD. But now if I reboot, the drive didn't appear to be mounted.
The device node was /dev/sda6 at the last tests. Thus I added it into the fstab as follows:

/dev/sda6 /mnt/usb auto rw 0 0

But the node is not created after my last reboot. Also I didn't have lsusb to see if the drive will be listed.

I am using the stock linux distribution:

Linux debian #1 Thu Mar 19 14:46:22 IST 2009 armv5tejl GNU/Linux

What else do I need to do to automate mounting my hdd at boot time and keep it reliable?

I plan to replace an existing server with mail, cvs and other services to save energy and only wake on lan the old hosts if I need to access them.

Also, what distro do you suggest for a openSuSE user?

My debian knowledge is not that much :-(

Any help out there?


Now I have also tested if it would be the USB plug from my USB hub. Thinking there may be an electrical contact problem I tried fixing this by deforming the USB plug housing (not the one in sheeva). But I still have to try more than one to plug in the hub into the sheeva to get the HDD start spinning.

Has anyone else got these problems?



7  Linux Stuff / General Linux questions / Re: Newbie having trouble finding my hard drive (USB hub + iomega) on: January 30, 2010, 10:47:43 AM

after some tries I got the drive running. But I needed to unplug my hub and then plug it again.

I have added the wait4usbdisks script mentioned in this forum but it seems not to work.
As my drive spins down very early I think doing a USB power down and up and then a mount -a
in a script instead of only waiting for a drive to be online.

wait4usbdisks: http://plugcomputer.org/plugforum/index.php?topic=485.0

What do I need to power up and down the USB bus?

Can I use dbus commands for that?

Any comments?


8  Linux Stuff / General Linux questions / Newbie having trouble finding my hard drive (USB hub + iomega) on: January 30, 2010, 08:52:59 AM

I have read a bit about hard drives and scsi and I used

root@debian:~# cat /proc/scsi/scsi
Attached devices:

My sheeva plug has the original linux from vendor GlobalScale Technologies.

My hard drive is a Iomega Prestige 500 GB hard drive.

I think I need usbfs driver or subsystem, as another usb memory stick is not detected.

Are there any documents how to getting a usb drive running on the base system?

Also I now have seen a message that makes me worry:

Apr 28 02:00:36 debian kernel: JFFS2 notice: (666) check_node_data: wrong data CRC in data node at 0x1cc57800: read 0x41e30dc0, calculated 0x4add1735.
