I have an ATmega328P-XMINI microchip (googling gave me a result that its an 8 bit chip).
Im new to embedded programming. And need some help getting on my way. For now im just trying to establish a connection with avrdude (im just trying to get a healthy connection loading code to the chip comes later). But i get this error. I dont know how to fix this or what is going wrong.
What i do know is that there is an usbdev input output error what i think is the culprit.
The other line exclaiming that the usb device is busy is also suspicous.
DISCLAIMER: I use gentoo and cause of this have no access to atmel studio (I have no access to windows programs).
command issued (tried with and without sudo):
sudo avrdude -p m328p -c xplainedmini
Error code:
avrdude: usb_open(): cannot read serial number "Connection timed out"
avrdude: usb_open(): cannot read product name "Connection timed out"
avrdude: usbdev_open(): WARNING: failed to set configuration 1: Device or resource busy

Any tips for debugging this problem in general im thankfull for.
Never mind i spent 20 minutes formulating the question and formatting it. Just to realize that plugging it out and in fixed it.
IM AN IDIOT!

I know this isn't the right place to ask this but this site has the most users on it. I recently bought a Kemp LoadMaster LM-2600 Load Balancer for my webservers. However, this unit didn't include an SSD because the previous owner decided to erase it. So, I downloaded the VirtualBox version of free VLM from kemp's website. Then, I used VBoxManage clonehd LMOS.vmdk LMOS.img --format RAW to turn the disk into a raw img file. Then, I used dd if=LMOS.img of=/dev/sdb to flash a USB with the os. Then, I booted my loadmaster with the USB.
The boot process went like normal until it finished booting and then the machine switched to runlevel 0 (Shutdown)
This is the logs I got when I plugged the USB into my computer (The log file was so big that stack overflow won't allow me to paste it here):
https://pastebin.com/5PbKzRi6
I noticed that it said something about eth0 being down so I plugged in an ethernet cable and booted it again. The same thing happened but I got a different error (The log was shorter so I labeled it):

Any help would be great,

USB problems in RPi typically happens because of a corrupted kernel, try to update it then give me a feedback.
I am trying to setup a Raspberry Pi Zero as a mass storage with dwc2 and g_mass_storage (using the last Raspbian image available).
I created the data storage file with dd, made it a FAT32 fs with mkdosfs.
I looked for a lot of things. I spent some time to understand that options should be passed in /etc/modprobe.d/g_mass_storage.conf
It is finally seen in ubuntu. My problem is : it is in read only mode.
I tried to set the ro option to y or n without any impact on the behaviour. I changed permissions on the file (777), it changed nothing.
here is the current content of my /etc/modprobe.d/g_mass_storage.conf file :
options g_mass_storage file=/piusb.bin stall=0 removable=y ro=n
here is the of dmesg from the ubuntu :

What to do to get a read/write mass storage ?
I reproduced your problem. I had a similar problem with the module g_acm_ms on Raspberry Pi Zero W. If you configure the module in /etc/modprobe.d/, then the system ignores the parameter ro=0. Perhaps this is due to the order of initialization of kernel modules. I got around this by adding the module to the blacklist and writing the initialization in /etc/rc.local. Thus, I managed to get an emulation of a read/write mass storage.
All steps:
Create and format the file:
# dd bs=1M if=/dev/zero of="/piusb.bin" count=2048
# mkdosfs "/piusb.bin"
Add modules-load=dwc2,g_acm_ms to end of /boot/cmdline.txt (after rootwait)
Add the string dtoverlay=dwc2 in /boot/config.txt
Prevent module initialization at startup:
$ echo "blacklist g_acm_ms" | sudo tee -a "/etc/modprobe.d/blacklist-g_acm_ms.conf"
Add initialization in /etc/rc.local above exit 0:
# nano /etc/rc.local
Add string:
/sbin/modprobe file=/piusb.bin removable=y ro=0 stall=0
Reboot system:
# reboot -h
P.S.: If you don't want to use USB for console output, you can use g_mass_storage instead of g_acm_ms.
UDP send of XXXX bytes failed with error 11
I am running a WebRTC streaming app on Ubuntu 16.04.
It streams video and audio from Logitec HD Webcam c930e within an Electronjs Desktop App.
It all works fine and smooth running on my other machine Macbook Pro. But on my Ubuntu machine I receive errors after 10-20 seconds when the peer connection is established:

==> Btw, if I do NOT stream audio, but video only. I got the same error but only with the "video" between the Log lines...
somewhere in between the lines I also got one line that says:

It does not seem to help. I am still getting these errors and I experience lagging on the other side.
Additional info: on Ubuntu the Electronjs App connects to Heroku Server (Nodejs) and the other side of the peer connection (Chrome Browser) also connects to it. Heroku Server acts as Handshaking Server to establish WebRTC connection. Both have as configuration:
{'urls': 'stun:stun1.l.google.com:19302'},
{'urls': 'stun:stun2.l.google.com:19302'},
and also an additional Turn Server from numb.viagenie.ca
Connection is established and within the first 10 seconds the quality is very high and there is no lagging at all. But then after 10-20 seconds there is lagging and on the Ubuntu console I am getting these UDP errors.
The PC that Ubuntu is running on:
PROCESSOR / CHIPSET:
CPU Intel Core i3 (2nd Gen) 2310M / 2.1 GHz
Number of Cores: Dual-Core
Cache: 3 MB
64-bit Computing: Yes

Could please anyone give me some hints or anything that could solve this problem?
Thank you
==============EDIT=============
I found in my very large strace log somewhere these two lines:
7671 sendmsg(17, {msg_name(0)=NULL, msg_iov(1)=[{"CHILD_PING\0", 11}], msg_controllen=0, msg_flags=0}, MSG_NOSIGNAL) = 11
7661 <... recvmsg resumed> {msg_name(0)=NULL, msg_iov(1)=[{"CHILD_PING\0", 12}], msg_controllen=32, [{cmsg_len=28, cmsg_level=SOL_SOCKET, cmsg_type=SCM_CREDENTIALS, {pid=7671, uid=0, gid=0}}], msg_flags=0}, 0) = 11
On top of that, somewhere near when the error happens (at the end of the log file, just before I quit the application) I see in the log file the following:
https://gist.github.com/Mcdane/2342d26923e554483237faf02cc7cfad
First, to get an impression of what is happening in the first place, I'd look with strace. Start your application with
strace -e network -o log.strace -f YOUR_APPLICATION
If your application looks for another running process to turn the work too, start it with parameters so it doesn't do that. For instance, for Chrome, pass in a --user-data-dir value that is different from your default.
Look for = 11 in the output file log.strace afterwards, and look what happened before and after. This will give you a rough picture of what is happening, and you can exclude silly mistakes like sendtos to 0.0.0.0 or so (For this reason, this is also very important information to include in a stackoverflow question, for instance by uploading the output to gist).
It may also be helpful to use Wireshark or another packet capture program to get a rough overview of what is being sent.
Assuming you can confirm with strace that a valid send call is taken place, you can then further analyze the error conditions.
Error 11 is EAGAIN. The documentation of send says when this error is supposed to happen:
EAGAIN (...) The socket is marked nonblocking and the requested operation would block. (...)
EAGAIN (Internet domain datagram sockets) The socket referred to by
sockfd had not previously been bound to an address and, upon
attempting to bind it to an ephemeral port, it was determined that all
port numbers in the ephemeral port range are currently in use. See
the discussion of /proc/sys/net/ipv4/ip_local_port_range in
ip(7).
Both conditions could apply.
The first will be obvious by the strace log if you trace the creation of the socket involved.
To exclude the second, you can run netstat -una (or, if you want to know the programs involved, sudo netstat -unap) to see which ports are open (if you want Stack Overflow users to look into it, post the output on gist or similar and link to it here). Your port range net.ipv4.ip_local_port_range=1024 65535 is not the standard 32768 60999; this looks like you attempted to do something about lacking port numbers already. It would help to trace back to the reason of why you changed that parameter, and the conditions that convinced you to do so.

Any suggestions would be greatly appreciated; I need this working for a college class on a tight schedule.
Many things could be wrong.
The first thing I would do is check the RAM size. If it exceed the amount on the board, this might happen.
Is the serial port & shell configured? I would suggest adding the standalone shell bundle.
If the symbol table is compiled as standalone, this can sometimes occur based on other configurations.
Compile the symbol table into the image.
In Work Bench:
Kernel Configuration -> CTRL+F, search "built-in symbol table", -> include it.
