I have 4 SSD cards plugged into my system. They show up as /dev/nvme[0-3]n1.
Using lspci -vvv I can get the PCIE slot numbers of these 4 cards. But how to match the PCIE slot number with the device name? For example one of the cards has the slot number 3b:00:0. What is the corresponding /dev/nvme[0-3]n1?
I have gone through /sys/bus/pci/devices but not found what I'm looking for. Google has not thrown up any answers either.
TIA
cheers
You may try searching for device name somewhat like this:
grep "3b:00.0" /sys/class/nvme/*/device/uevent
Then you will need to extract device name from the output:
/sys/class/nvme/nvme0n1/device/uevent:PCI_SLOT_NAME=0000:3b:00.0
This will be the string in place of the asterisk.

I need to fix the microphone volume for any user in Ubuntu 16. What I want is to fix the volume, say, to %40, and keep it at that value for all times. It must be changed by no user except root. How can I do such a config? And with what tool?
Thanks.
All mixer controls of a card are managed with a single device node (/dev/snd/controlCx), so it is not possible to use file permissions for this.
However, you could program a separate tool that calls
snd_ctl_elem_lock() for the mixer control that no other program should
be able to change.

Hi every one
on a web server running Centos 6 with 4 Network Interfaces, we have to setup/Merge all 4 interfaces to be shown / used as a single NIC, we know it's possible but we forgot the technical name of the solution, we need just the name to google it if it's possible.
Thanks
The word your looking for is "bonding". That's what it's called in Linux.

I have two USB devices which appear as /dev/ttyACMn (a barcode reader and a motor controller). For each of them, when I try to open them in the first 15 seconds after plugging in, I get a "device or resource busy" error. After more than 15 seconds, they open fine. Do you have any idea what's causing it?
I tried using lsof to check if a process is using the device, but it finds no such process (it finds my process after I manage to connect to the device).
I'm currently using Ubuntu 14.04, kernel 3.13.0 64-bit, but I have seen this behavior in earlier Ubuntu versions too.
Thank you very much,
Noam
I think the problem is ModemManager. It scans serial interfaces on startup to see, if they belong to a modem.

Today I bought a memory card "Silicon Power" SDHC 4ggb, class 10and I need to know, this memory card is compatible with raspberry pi B or not ?
Your card is not listed on the Embedded Linux Wiki's list of compatible SD cards for the Raspberry Pi. Two other cards from this manufacturer are listed as not compatible, so the odds are that you may experience problems.
