Hi @joellama, what does ```console cat /sys/module/usbcore/parameters/autosuspend ``` return on your ubuntu 20.10 machine? Cheers, Andreas 😃

You mentioned it's sporadic, so my guess would be some weird USB problem... On linux PCs that are used for scientific measurements I'd generally recommend disabling everything related to power...

You're welcome 😊 And fingers crossed 🤞 🤞

Hi Joel, Another thing worth trying would be to run the 3 spectrometers in three different processes. (You could test by running a script continuously with only one spectrometer.) Did...

So according to the datasheet the NIR256 has the product ID 0x1010 and if I understand you correctly you created an inf file for the NIR256 so that it uses...

hmm... can you report the output of: ```python import seabreeze.pyseabreeze.interfaces.defines as sbdef print sbdef.ProductIds ```

Hey @anffray, sorry for the late reply. I can't really see an issue with your code (although I might miss something. It's hard to debug without the hardware) one more...

Sorry, my mistake: ``` import usb.core from seabreeze.pyseabreeze.interfaces import NIR256 import numpy as np dev, = list(usb.core.find(idVendor=0x2457, idProduct=0x1010, find_all=True)) s = NIR256() s.open_device(dev) # < ADDED THE FOLLOWING LINES s.usb_send(struct.pack('

Well looks like you're getting closer to a working implementation for your spectrometer model :+1: If this does not look like a spectrum, when you plot it, try using `get_unformatted_spectrum_length`...

Hi @LMSC-NTappy, Thank you for reporting ❤️ It's a bit funny, because this message has been in `python-seabreeze` for more than 2 years and you are the first to report...
