No port available for Arduino uno on Linux

Official Hardware UNO Family UNO R3
1

I hope this is the right place for this topic.
I am running Linux Mint Victoria, and after swapping the SSD from an old desktop to a newer one, the arduino IDE can't find the USB port for the Arduino board.
I have googled this extensively , and ran as many of the command lines in a terminal to try and resolve my problem.
I've restarted my pc with the Arduiono still plugged in.
I've tried ls /dev/tty*, as well as dmesg | tail -f, and unplugging the bard , then running dmesg | tail -f again to see if there was any difference, but there was not. When I ran ls /dev/tty* ttyS4 is listed but when I try to upload a sketch, I get this:
avrdude: stk500_recv(): programmer is not responding.

What else can I do.

Thanks

What does this mean, exactly? Does it mean that when you unplug/plug your cable in that you're not seeing any new output from dmesg? Or does it mean that you see the same output when you plug it in and unplug it? Or does it mean something else entirely?

3

It means that after I unplug / plug in there were no new messages, so yes I am seeing the same messages, and they all relate to libre office-soffice.

4

No new messages means that the computer isn't even seeing the Arduino.

Power only cable?

Does the ON LED on the Arduino light up when you plug it in?

Does another USB device work in the same port?

5

Yes the led on the Arduino lights up, and other devices work fine in the same USB port

And just for information
dmesg | grep tty

And this:

So the Arduino's getting power, and the port works. That pretty much leaves a power only cable (or one with a damaged data line). Could be a bad USB chip/connector on the Arduino too I suppose.

7

Yes you could be right there, but as I have only got the one , I'll have to get another.
I tried another Arduino Uno, and get this when trying to install bootloader
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00

Just ran this with the other Arduino plugged in:
dmesg | grep tty

[19148.016027] cdc_acm 1-10.1:1.0: ttyACM0: USB ACM device

And this:

So this Arduino is being recognised , but the IDE doesn't see the port ttyACM0.

Ah, so a bad USB connector/chip on the first Arduino by the sounds of it.

Can't help you with the IDE as I don't use it.

Is your username in the group dialout. It needs to be to access the serial port.
Not sure if your error msg means you can't access your serial port though.

If lsusb does not show a new usb device, that is not the problem at this stage.

Not in this case. @avalon66 selected ttyS4 which is not a serial port. A board would be ttyACMx or ttyUSBx (where x is a number).

My username is in the group dialout, and when I select either ttyS0 or ttyS4 , which is listed when I run
dmesg | grep tty
[ 0.095631] printk: legacy console [tty0] enabled
[ 0.417609] 00:03: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A

I still cannot upload any sketch.

Thanks

The 16550A is a hardware serial port inside your computer and has nothing to do with Arduinos.

lsusb does not recognise your board, dmesg does not give any reaction when you plug / unplug the board so /dev/ttyS4 is not your board.

Are you sure that the cable that you use is good? Try another cable.
Can you test the board on another computer (friend, family) to make sure that the board is OK; it does not have to run Linux.

I have ordered a new cable to see if that makes any difference.
I tried on another linux, ubuntu, computer, but there was a problem running some of the commands, and after I installed or downloaded the ide file , no ports were listed.

Thanks

What I don't understand is when I run:

dmesg | tail -f

That the arduino is on port? ttyACM0, but yet the ide does not list that port, only ttyS0 and ttyS4

15

1st you've done a good job troubleshooting before posting here.

ttySX is just as @sterretje say, regular serial ports and detected early in the boot.

USB is added later on.

So with a new computer it doesn't work?

16

It disconnects almost right away. Could be signs of a bad usb cable or otherwise loose connection.

17

@ledsyn
No, it could be no required rivers installed or the cable on the other computer

18

Maybe try

sudo apt-get remove brltty
19

Drivers sure, but in the case of Linux, they are part of the kernel.

@ledsyn,
yes it could well be, but I'm not technical enough to find out.
