How Do I Install FTDI Drivers In Debian?

Hello. I have a Raspberry pi using Raspbian. I want to set it up as a tv headend and I have a problem setting up my tuner.

The specific tuner (Avermedia H810) has a TDA18271HD chipset which should be supported by my kernel (3.18.7+).

Can anyone help me sort it out?

Thaaaanx!

I'm a newbie with a Linux box running Ubuntu 10.04 that I'm attempting to setup to control a desktop CNC. The box didn't have a parallel port so I purchased a SYBA PCI to Parallel card. Following the instructions from the card I ran "lspci -v" and below is what it showed;

03:00.0 Communication controller: NetMos Technology PCI 9835 Multi-I/O Controller (rev 01)
Subsystem: LSI Logic / Symbios Logic Device 0010
Flags: medium devsel, IRQ 19
I/O ports at ec00 [size=8]
I/O ports at e880 [size=8]
I/O ports at e800 [size=8]
I/O ports at e480 [size=8]
I/O ports at e400 [size=8]
I/O ports at e080 [size=16]
Kernel modules: parport_serial

The instruction stated to use the following command;

/sbin/modprobe parport_pc io=e080, irq=19 If I read the instructions correctly.

Unfortunately, the instructions didn't say where to add this command line. Also I didn't see any drivers listed on the disk for the chipset referenced above. So is the card trying to use a generic driver installed by Linux?

Your guidance is greatly appreciated!!
Thank you Brian

I have a WiFi dongle that said to support GNU/Linux, however no drivers were found on the CD, after hours of research i found this and installed the driver, I'm pretty sure my device is listed as supported, but the device is still not recognized, it is listed on lsusb command, but not recognized by any WiFi program like WiFi Radar and wireless-tools, also when i use the iwconfig command, this is what i see, i really need this wireless connection working, can you help, please?

My question is: where can I find

where is my android device mounted at on my OS? (Ubuntu 13.10, Alcatel Fierce 2)

It isnt showing up in Gparted, fdisk, and Im not exactly sure where to look in dmesg

I have no problem mounting my Android device.

Im looking for where it is mounted in dev/sd*

I'm trying to get a Canon CanoScan 4200F scanner to work in both Kubuntu 12.04 and Calculate 13.6, and I've had no luck, using either SimpleScan or Xsane. The Canon website is no help; it simply says that Canon supplies no drivers for that device for any Linux distro. Does anybody know where to get drivers that work w\ Canon devices?

The following is the output from lsusb:
lsusb | grep -i 'canon'
Bus 007 Device 002: ID 04a9:221b Canon, Inc. CanoScan 4200F

Thanx in advance.

Hi,
I am trying to write to usb flash drive using a C program. I have just created some files in USB device and doing my tasks using fopen,fread and fwrite on those files. I was just wondering what is the standard data rate that can be achieved using fwrite() on a file in usb. Secondly what is better way of transferring data to USB flash drive using C Program? Obviously I am a newbie

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.

Machine is booted into Grub Menu
I am using rescue linux

by doing fdisk -l

it shows
Disk /dev/sda : bla bla bla
Device Boot
/dev/sda1 *

so i install grub using this command in shell

grub-install /dev/sda1

it shows

installation finished. No error reported
This content of the device map /boot/grub/device.map


After re-boot it again shows grub menu

Hello everyone.
The sound isn't working on my debian live usb.
I've installed pavucontrol hoping that this would turn on the sound somehow. But it hasn't.

The program is showing RS880 HDMI audio [Radeon HD 4200] as my output device.
The play back bar moves when I play video on youtube but there is no sound.
On the configuration tab, I've tried all the options under 'built-in audio' - but none of these seem to work.


aplay -l

Code:

Don't know why there are 3 playback devices...

lspci | grep -i audio

Code:

00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) (rev 40)
01:05.1 Audio device: Advanced Micro Devices [AMD] nee ATI RS880 HDMI Audio [Radeon HD 4200 Series]

Not sure why there appears to be two sound cards...

On a Ubuntu site about a similar problem with the same sound card, they suggest creating /etc/asound.conf and adding code to it http://ubuntuforums.org/showthread.php?t=1647400
However, at this point, I'm a bit lost.
Can someone help please?

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
