The error "USB device 6 (vend/prod 0x603/0xf2) is not claimed by any active driver." is in dmesg every time I connect my Logitech keyboard to my system. I also tried (all with the same error):

Recently, I created a device sc0 through device mapper. The divice could be found in /dev/mapper/sc0. My problem is that the device doesn't exist in /dev/partitions which will block my following test.BTW, I found dm-0 in /dev/partitions. Is it the same as /dev/mapper/sc0? But the device /dev/dm-0 doesn't exist!
View 2 Replies View RelatedI am working on an embedded system, which is an USB MSC device that supports some vendor specific scsi commands. I am using FC10 laptop as USB host for testing, and it runs some small apps based on sg3. All has been well for ~ a week. The FC10 laptop is able to communicate with the device and retrieve data. Suddenly, starting from today, the laptop is not able to properly detect the device. When plugged-in, the MSC device is detected as input device (I thought). This is observed from "dmesg" output and changes in "/dev/input/".The device under development is running at full speed. When I connect to winXP, no problem. A windows file explorer pops up, showing the content of the drive.Also, the FC10 has no problem with other USB flash drive (high speed).

For those that use Virtualbox on their slackware host and have a windows (xp) guest running. I have tried various settings for sound (Alsa, PulseAudio), the AC97 drivers are installed in the Windows xp guest os, but there is no sound and there is an unknown audio device (in the windows device manager). If I remove the AC97 drivers and use the soundblaster16 drivers in the Vbox settings there is no unknown sound device, but there's still no sound. why I can't get sound working?

I recently switched from Windows XP to a clean install Ubuntu Karmic Koala 9.10 but it seems to be quite a problem to get the wifi up and running. In Windows the nearby network all appeared in network connections but the same section in Ubuntu is empty. So I decided to go with the ndiswrapper guide to solve the problem with an unclaimed driver. After an entire day messing with my computer I'm still not close... Below follows excerpts taken from the Ndiswrapper guide with posted results from my computer. "ndiswrapper won't work until it thinks that your Windows drivers have been properly installed and that they are the appropriate ones for your wireless card. You can run the command: ndiswrapper -l"
result:
WARNING: All config files need .conf: /etc/modprobe.d/blacklist, it will be ignored in a future release.
WARNING: All config files need .conf: /etc/modprobe.d/ndiswrapper, it will be ignored in a future release.
net5211 : driver installed
device (168C:0013) present (alternate driver: ath5k)
So I've posted the result the name of my wireless card below: lspci -nn
Result:
00:00.0 Host bridge [0600]: VIA Technologies, Inc. CN333/CN400/PM880 Host Bridge [1106:0259]
00:00.1 Host bridge [0600]: VIA Technologies, Inc. CN333/CN400/PM880 Host Bridge [1106:1259]
[code]...
It seems like the network is disabled or unclaimed or both. What to do? I'm stuck after spending an entire day trying to install the wifi. I had no problems in Windows XP but it seems to be quite impossible in Ubuntu.

how to write a device driver for USB

Of course, it's Windows only, and XP only at that. However, the data that needs transferred between the device and the computer should be fairly basic, unless it offloads a lot of processing to the computer. I'm not a programmer, nor do I play one on TV, but I have written some fairly complicated microcontroller programs and some basic Java GUIs. Besides writing the actual code, how hard is it to do whatever needs done to make a Linux device driver, apart from the code to make the device work?
Is there an easy example of a block device driver I could follow as a guide to write my own module?

It's easy to bind a device to a usb driver by doing something like
