dmesg and lsusb give same output whether board is connected or not

-

i have 2 arduino fio ports. running ubuntu 11.10, , installed arduino 22 via apt-get (0022ubuntu0.1). have restarted after installation.

in tools tab, serial port menu disabled.

the board connected computer via usb, , yellow/orange diode on.

i have read quite few topics on website find solution, , helpful people on forum asks result of dmesg , lsusb. however, when lsusb, result same when board connected when not. same true dmesg; same output connected , disconnected board. have tried both of 2 arduino fio boards.

isnt dmesg , lsusb supposed print additional or different information when boards connected?

sincerely, velle

are cable, usb port, , hubs in path known good?  if plug else same cable , port, behavior?

cables go bad, , had bad 1 new right out of box last week.

dmesg shows syslog entries, can buffered few seconds (but aren't).  lsusb shows state of bus @ time execute command.  think must root run lsusb.

ATmega2560-Arduino Pin Mapping

hi community, in last days working on project using arduino mega 2560. on planning pin using found bugs in atmega2560-arduino pin mapping . if right there labels (such pwm) in 'mapped pin name' @ wrong row ( mixed pin numbers right one...) in attachment openoffice calc , pdf file corrected table. ( hope ;-) ) i post here tab separated table : code: [select] arduino mega 2560 pin mapping table atmega 2560 pin out arduino mega function nr name function function function mapped pin name function function datasheet 1 pg5 oc0b digital pin 04 pwm 2 pe0 rxd0 pcint8 digital pin 00 rx0 (usart0 receive pin, programming data input or pin change interrupt 8) 3 pe1 txd0 digital pin 01 tx0 (usart0 transmit pin or programming data output) 4 pe2 xck0 ain0 (usart0 external clock  input/output) 5 pe3 oc3a ain1 digital pin 05 pwm 6 pe4 ...

Crossfader Arduino Tutorial

-
hello i'm super newb please don't bash me much. i'm using led's , i've connected them correctly (finally) , wondering why program here ( http://www.arduino.cc/en/tutorial/colorcrossfader ) doesn't work? say's haven't declared crossfade. read directions on top , said crossfade needs used list order of colors. isn't declared in main part (void loop() )? or need declared before? nevermind void on bottom , needed before voidloop. lol anyways playing rgb led's wondering if has specific way of making them fade in , out different colors? (brightness , color mixing) code: [select] /* * code cross-fading 3 leds, red, green , blue (rgb) * create fades, need 2 things: *  1. describe colors want displayed *  2. list order want them fade in * * describing color: * color array of 3 percentages, 0-100, *  controlling red, green , blue leds * * red red led @ full, blue , green off *   int red = { 100, 0, 0 } * dim white 3 l...
