Using the raspberry Pi 2 mod B to programming arduino with a usb externally powered hub

Start with R Pi powered from wall not usb hub. Also Arduino powered on jack from wall not usb hub. If this works, then the current/voltage on the hub is too low to handle the load. Many powered hubs are not up to the job.

I would also suggest to try latest Raspbian to see if that works rather than Kali, while Kali may work I have not seen it on the official supported Raspberry PI list of downloadable OS's

To CM & PO: Great Comments/Tips as usual. Thx. What Thread/Discussion/even-MOOC has the instructions/schematics for programming the Arduino via it's USB Port? The "Main" Arduino Website?

AAR Not to cloud the Issue, but wouldn't a Gertboard (aka Gertduino Board) connected to RaspPi be a better way to go? I know this is Monday Morning QB'ing but I am researching the ways certain devices are best for any given situation. I was thinking of possibly getting a Gertboard, and use it in Conjunction w/ my RaspPi and my Copy of Matlab. Code(d) Projects will be run on the latest-model "Original" Arduino OR on the Gertboard (independent of the RaspPi). I know that the Arduino has a low current draw (i.e.Possible Battery-powered Projects). For "wake-up" from hibernation projects, possibly use the Gertboard b/c I believe the Gertboard has a RTC (Real-Time-Clock),

At first I dismissed the Arduino as a Toy, but have since changed my mind. All God's creatures (including microcontrollers) have a place in this world. It is not until we know/understand their attributes, that we begin to appreciate them. BTW I think a Arduino has lower current draw than a RaspPi Zero?

Yep try a simple solution of  a plain Raspbian distro initially, then if the problem persists try another USB hub and also try a different PSU for the RPI since if you are getting problems with a basic Arduino attached to your USB then you are probably having problems with the power in general.

Rpi is running from a 2.5A wall adapter but arduino is not running off wall but my usb hub can handle upto 2.5 A at each port cus my arduino powers up fine with usb hub it just wont show up in /dev/tty% also same case with keyboard and mouse.

Please list the make and model of the hub. There may be a problem with it. Do you have another hub to try?

Clem

Yes, please give us Make & Model # of the powered(?) Hub. AND re-check your USB cable connections.It is NOT like a RJ45 Ethernet Router where your connection ports are the same (w/ exception of the WAN RJ45). AAR one USB connection between the Device and (powered?) USB Hub SHOULD be Male Full-size USB-A---connected to -EITHER -Female Full-Size USB-B (on the Hub) OR a small Size micro USB -B (on the Hub)

Another Words, At least One connection to the Hub should be" A-to-B" . Then anything else that you add on (to the Hub) can be "A"

This is the way I did it in Spring 2013, where I connected an old USB 1.0 powered hub to my (2013) RaspPi.

BTW in the original Post that started this Discussion Thread: Q1: where "... i am in dialout group..." was quoted. What is the significance of this? Q2: where "...latest usb drivers usbutils..." was quoted. What is the significance of this?

I just connected an Arduino to my pi, directly to one of the usb ports and it showed up as

/dev/ttyACM0

I was able to verify this by typing

dmesg

and the last lines of the output were

[682106.515303] usb 1-1.2: new full-speed USB device number 5 using dwc_otg

after connecting via a hub dmesg reported

so /dev/ttyACM0 would be the device I would tell the arduino ide to communicate through

btw, using raspbian, I was able to do

sudo apt-get install arduino

to install the ide. It's an older version, but it should meet most needs.

I get the same and  I think they do to except not with the HUB. I feel it may be something to do with the HUb it's self or the boot/power on order.

Which Arduino version is it BTW???

They are all slightly different and the USB to serial chip on each will most probably be enumerated differently in each case.

try the command "lsusb -vv" and see if Linux can even see your arduino's serial chip on the bus. If it can but there is no driver then you may need to make sure the right serial driver is run before hand. If not then it's more likely to be the HUB or power up issue.
