Unable to reload udev rules on Raspberry Pi 3 #51

Closed benjaminesse closed 7 years ago

benjaminesse commented 7 years ago

spectrometer and system information

current problem

Installation of python-seabreeze is fine, but when I try to reset the rules in /etc/udev/rules.d/ by running:

sudo udevadm --reload-rules

it returns 

udevadm: unrecognized option '--reload-rules'

After googling I haven't found much to help, I am new to the Raspberry Pi. I have tried 

sudo udevadm control --reload-rules

which executes with no error but doesn't allow the spectrometer to be detected.

I have tried several reboots and unplugs/replugs of the spectrometer.

steps to reproduce

Step by step instructions to reproduce the error. The more detailed the better, but please use some common sense:

  1. Download 10-oceanoptics.rules and copy to /etc/udev/rules.d/
  2. Run 
    sudo udevadm --reload-rules
  3. Returns message: 
    udevadm: unrecognized option '--reload-rules'

In python, running 

import seabreeze.spectrometers as sb
sb.list_devices()

returns

[]

with no spectrometers attached (as expected) and

usb_claim_interface() returned -1 - did you copy os-support/linux/10-oceanoptics.rules to /etc/udev/rules.d?
Could not open device with ID 0. error=-1

Any light you can shed would be gratefully received.

Many thanks!

Hi @benjaminesse,

sorry for the long delay. What happens when you run your python code as root with a spectrometer attached?

-Andreas

benjaminesse commented 7 years ago

Hi,

That works fine, it finds the spectrometer with no problems. Is there a way around running it from root every time? I'm not too familiar with Linux, I have used it sporadically but most of my development has been in windows, so apologies if I'm missing something!

Cheers,

Ben

ap-- commented 7 years ago

See if your user is in the "plugdev" group: see which groups your linux user belongs to

And create the "plugdev" group and add your user to it if necessary: add a user to a group

-Andreas

soumendras commented 7 years ago

Hey wait...i have the exact same problem ....i did not understand how benjamin solved his problem ...please help me solve it ...... and AP ....when i write groups in my pi user name it returns plugdev

ap-- commented 7 years ago

your udev rules are installed correctly if there is a new symlink created in /dev after you plug in your spectrometer. This symlink (if you have a USB2000 spectrometer, for example: /dev/usb2000-12345, where 12345 is some number or string) should be owned by the plugdev group.

benjaminesse commented 7 years ago

Hi,

I reloaded the udev rules fine with the update you referenced above, but I still can't connect without running the code from root.

I checked /dev and couldn't find a symlink (I'm running a Flame so I'm assuming it will be of the form "FLM-12345")

Thanks again

ap-- commented 7 years ago

I think the flame should show up as a usb2000plus-

what's the output of lsusb when spectrometer is connected?

benjaminesse commented 7 years ago

There is no USB symlink either. The output of lssub is:

Bus 001 Device 006: ID 2457:101e  
Bus 001 Device 005: ID 03f0:034a Hewlett-Packard 
Bus 001 Device 004: ID 0461:4d22 Primax Electronics, Ltd 
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
ap-- commented 7 years ago

so the udev rule for the USB2000plus will match. (The flame acts like a USB2000+ on the driver side)

ATTR{idVendor}=="2457", ATTR{idProduct}=="101e", SYMLINK+="usb2000+-%n", GROUP="plugdev"

when your spectrometer is plugged in what does the following command return:

ls /dev/usb*
benjaminesse commented 7 years ago

It returns

ls: cannot access /dev/usb*: No such file or directory
ap-- commented 7 years ago

and 

ls /etc/udev/rules.d/
benjaminesse commented 7 years ago 
10-oceanoptics.rules 99-com.rules
ap-- commented 7 years ago

Hmm, this is most likely due to your udev version. Try using an older version of the rules from here

download the file linked to above and overwrite the file /etc/udev/rules.d/10-oceanoptics.rules on your rpi.

make sure that when you type cat /etc/udev/rules.d/10-oceanoptics.rules it says ATTRS everywhere and not ATTR (as it does in the newer version of that file)

after that reboot your rpi.

If this doesn't help, I can't really provide further help. It's best if you google how to debug udev rules and try to figure out why the provided rules don't match. It's not complicated to do that. You'll find a tutorial easily. Good luck!

benjaminesse commented 7 years ago

Nope, still got the same problem. I'll look into the udev rules then, thanks for your help!

ap-- commented 7 years ago

Np.

one more quick thing to try: use the newer file again (the one with ATTR) and delete line 4, the one that starts with SUBSYSTEM... save it. reboot.

If that didn't help, and you figure out what's wrong, it would be great if you could report back! Good luck!

soumendras commented 7 years ago

when i try to run sudo python ......i cannot import this "import seabreeze.spectrometers as sb" .....says no such module

ap-- commented 7 years ago

@soumendras https://stackoverflow.com/questions/25346171/cant-import-module-when-using-root-user

ap-- commented 7 years ago

@benjaminesse run lsusb it returns something like:

Bus 001 Device 006: ID 2457:101e  
Bus 001 Device 005: ID 03f0:034a Hewlett-Packard 
Bus 001 Device 004: ID 0461:4d22 Primax Electronics, Ltd 
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

2457:101e is your spectrometer. Remember Bus 001 and Device 006. and use these numbers in the following command:

udevadm info --attribute-walk --name=/dev/bus/usb/001/006

post the output here.

soumendras commented 7 years ago

in my case the above command returns this

soumendras commented 7 years ago

@benjaminesse any update on how did you run python as sudo and still call those dependencies?

benjaminesse commented 7 years ago

Hi @soumendras, from that tutorial (and anyone correct me if I am wrong) when you run python from root the normal version associated that is used when you use the command

python hello.py

is not necessarily the same, so any libraries you have installed (such as the python-seabreeze) aren't installed in that version. I got around this by putting

#!PATHTOPYTHON

as the first line in the program replacing the PATHTOPYTHON with the actual path eg

#!/home/pi/berryconda3/bin/python3.6

for me. You then run it from root by typing

sudo ./hello.py

in the command line.

@ap-- I tried your suggestion of removing the lines and it worked, I now have no issues getting the program to detect the spectrometer, thank you! The output of the command you posted 2 comments back is:

@benjaminesse awesome! I'll fix this at some point in the future, until then we'll leave this open for people who run into the udev issue.

Note to self: udev SUBSYSTEM needs to match against "usb" not "usb_device" on raspbian jessie ?!?

WORKAROUND

if you're on raspbian and you have this issue open the 10-oceanoptics.rules file and replace "usb_device" with "usb" in line 4.

gabriel-cruz commented 5 years ago

I had the same problem as this, but my rpi3 does not even recognize the spectrometer when connected, in the lsusb command it is also not listed. I followed all these steps and the tutorial and nothing has changed, what do I do? The model of the spectrometer is the USB2000 +

if you're raspbian and you have this issue open the 10-oceanoptics.rules https://github.com/ap--/python-seabreeze/blob/master/misc/10-oceanoptics.rules#L4 file and replace "usb_device" with "usb" in line 4.

Yes, I did it, it's like this: SUBSYSTEM!="usb", ACTION!="add", GOTO="oceanoptics_rules_end". Is that correct?

It is like, backspace from e of device to underscore. Just look for usb_device in the whole document and replace it by usb.

Are you sure u r calling the right python. Remember python and sudo python will be calling different versions. Make sure u call the one where u installed miniconda.
