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?

    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.
