Double TtyACM Node Device From Sony Ericsson C510

I have a USB fax modem, and it logs the following errors when turned on.

I know it is impossible to know for sure, but think it is hardware related? Any chance to salvage?

Also, what are the steps to start troubleshooting?

Thanks

Hello everyone.
I have just installed debian stable non-free onto my hard drive but the sound isn't working.

I've been to the debian site https://wiki.debian.org/SoundConfiguration and found that 'users' don't automatically have access to audio (for security reasons).
So I did the following command as root (sudo):
Code:

adduser USER_NAME audio

Now when I am 'user', I can get sound.

I also did:
Code:

chgrp cdrom /dev/sr0
adduser USER_ID cdrom

This allows 'user' to get sound from the cdrom.

I then went onto the debian soundfaq https://wiki.debian.org/SoundFAQ

From the 'lspci -v' command, I get these 2 outputs which have the word 'audio' in it:
Code:

01:05.1 Audio device: Advanced Micro Devices [AMD] nee ATI RS880 HDMI Audio [Radeon HD 4200 Series]
	Subsystem: Giga-byte Technology Device 960f
	Flags: bus master, fast devsel, latency 0, IRQ 19
	Memory at fdefc000 (32-bit, non-prefetchable) [size=16K]
	Capabilities: [50] Power Management version 3
	Capabilities: [a0] MSI: Enable- Count=1/1 Maskable- 64bit+
	Kernel driver in use: snd_hda_intel

00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) (rev 40)
	Subsystem: Giga-byte Technology Device a102
	Flags: bus master, slow devsel, latency 32, IRQ 16
	Memory at fe024000 (64-bit, non-prefetchable) [size=16K]
	Capabilities: [50] Power Management version 2
	Kernel driver in use: snd_hda_intel

So I have 2 sound cards.

The debian website says: 'If sound does not work for root account as well, then that means that either your sound card is not supported by Debian or it was not configured properly'.

Ok, so the first part of the statement is worrying.
So I went to the debian device driver check page http://kmuto.jp/debian/hcl/ and did 'lspci -n'.
The output can be pasted onto their web page and debian will say if the sound cards are supported.
The web page shows that the sound cards are supported:

Quote:
10024383 Yes Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) snd-hda-intel v2.6.25
10029715 Yes Advanced Micro Devices [AMD] nee ATI RS880 [Radeon HD 4250] radeon v2.6.35-
1002970f Yes Advanced Micro Devices [AMD] nee ATI RS880 HDMI Audio [Radeon HD 4200 Series] snd-hda-intel v2.6.27-
So now I'm guessing that my sound cards are 'not configured properly'. But I've run a Youtube video and then changed the sound cards under alsamixer and I still don't get sound.
Is there is a simple solution to this please? Thank you in advance.

Hello! Who can help me? I remenber this problem have never occured when I was using CentOS 6.4. This time I am using Fedora 19 and problem occured as follow.

dnw is a download tool for ARM. Maybe secbulk is it's driver. I don't know much about it. Any help would be appreciated. Thanks!

I am new to drivers development under linux kernel. After starting with the simple examples from the book Linux Device Drivers v3, I realised that the block driver API has been totally changed since the kernel 2.6.31 or maybe later versions, and I couldn't find any documentation about the new API and how to use it. There are just some few comments in the source code.

After struggling for one month I almost had something working but few parts are missing or I misunderstood something.

Here is the situation :

After fetching the request with blk_fetch_request(q), I use the macro __rq_for_each_bio for handling the full request
To transfer the segments one by one I use the macro bio_for_each_segment(bvec, bio, i) that loops over all the segments in a bio

My question is :

I need to do some DMA from/to my device (the dma engine is within the device), that's why I need some address that I could use it to DMA from/to
Which buffer should I use ? for the moment I use the buffer returned by char *buffer=bio_data(bio), Does "buffer" corresponds to the physical buffer that I can use for DMA
How to end the request in this case ? using __blk_end_request_cur(req, 0) ? or using __blk_end_request(req, 0, bytes) ?

If you don't have an answer to any of these questions, where can I find a useful documentation for the new API of the block device drivers.

Hi,

I am trying to understand the difference between char devices and block devices.
I understand the basic, which is that char devices input/output data one character at a time, whereas block device input/output data block by block. But for char device driver, most of the time we are able to read/write an array of data using the read/write system call. This "array of data" sounds like a block of data to me, except that it's not fixed in size as for block devices. With this thinking, can I say that I can effectively achieve block read/write with a char device driver?
And what are the other differences?

Thank you all,
Wei

I install fgrlx driver on vivid os the driver look like is istalled correct on system and built the necessary kernel modules because the dpkg log not report any errors, i configured the driver by simple commands like:

sudo aticonfig --initial

sudo aticonfig --screen-layout=on

i reboot the machine , but i face an strange issue the boot splash screen is hangup,i cant enter my lvm password to boot the system, i was have a chance to boot into rescue mode when boot to rescue mode the display not read by the system i try to export display by

export DISPLAY=:0

I try to configure /etc/X11/xorg.conf there is not good resaults the boot splash still hang up

I edited the grub , i uncomment "quiet splash" modified by "nomodeset"

i can boot without boot splash but im faced other issue i cant switch to virtual tty

i dont know is this a bug in the driver or in the kernel

any suggest

I have a debian OS on a partition on my hard disk (sda1).
There was no sound because the ati rs880/radeon 4200 sound card needed drivers which were only in the debian 'non-free' version'.
So I added the non-free version to my install and also had to make a change to the GRUB bootloader file.
After that, I got sound.

Now I've installed a new debian distro to my second partition - sda2.
This time I ensured I installed the debian non-free version.
But I'm having trouble installing the drivers for the sound card.

I go into Synaptic package manager to install the relevant drivers and it gives me an error message:
Code:

Configuring libfglrx - install Fglrx driver despite unsupported graphics card?

I'm not sure what that means because I want the drivers for my sound card - not graphics.
When I press the 'Help' button, it says:
Code:

This system has a graphics card which is no longer handled by the Fglrx driver...
The above card requires either the non-free legacy Fgrlx driver 
(package fgrlx-legacy-driver) or the free Radeon driver (package xserver-xorg-video-radeon).

This is fine because I can just install the 'free Radeon driver'.

But the Help message then says:
Code:

Before the Radeon driver can be used you must remove Fglrx configuration from xorg.conf 
(and xorg.conf.d/)
Note that switching to the free Radeon driver requires the fglrx-driver package to be purged (not just removed).

So now I don't know what to do. Has anyone had this error message?
I know I can enable sound and have no problems with the graphics card because that's what happened with my original install on sda1.

But with the install on sda2, I don't know how to approach this problem.
Can anyone help please?

Hi.
This is the first time I need to do this. New to Linux... :-)

I need to have two Ethernet connections in my laptop working. Its Ethernet RJ-45 jack works fine. I had to get a new Trendnet USB/Ethernet adapter for the second connection. After I connected it for the first time to my laptop having Fedora 15, I get:

The first connection is em1 and working fine, but I never see a second ethx interface. I figured I'm missing the driver for it. So, I went to the read me file from the cd, where these files a
- asix.h
- ax88179_178a.c
- Makefile
- readme

The readme instructions for Linux say: you need the kernel sources installed on the machine. Make sure the version of the running kernel must match the installed kernel sources.

1. What are kernel sources and how I can download them for this installation? Please, keep in mind I do not know Linux. This is my first time doing more than just the very basics.
The instructions are called "ASIX AX88179_178A USB 3.0/2.0 Gigabit Ethernet Network Adapter Driver Compilation & Configuration on Linux."

My kernel is 2.6.38.6-26.rc1.fc15.i686.PAE

I have no idea how to start.
Thank you!!!

Hello,
know anybody how to delete that error at the end of dmesg?
If was not here before I installed the fglrx instead of the radeon driver.
