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

e14 Contributor

HI i have started to use a usb externally powered hub due to power demands of arduino and current drops in rpi but when i connect the usb cable from hub to arduino port is not available in ide. I dont understand i mean i tried various things like

> i am in dialout group

> latest usb drivers usbutils

> i checked the lsusb hub seems to work fine

> ohh and one thing i noticed usb keyboard or mouse or anyother HID device wont work with rpi when pluged into USB hub but storage devices like external HDD and flash drives work with hub // hub is fine tho i checked it on other system it works fine.

> my config : rpi 2 mod b+ 1GB( 2.1 A power supply)  /  OS debian (arm kali linux)  / 2 HID's 1 USB hub (connected)

i dont understand how do i make it work?

    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?
