So i recently bought a used Atten ADS1062CML for 60USD. Now, i never had an oscilloscope of my own before, i just used the ones at my school. I heard that you should update the firmware, but I cant find anything, not even on the manufacturers website (which now sells only soldering stuff). Also, I downloaded easyscopeX from siglent site, since it seems some atten oscilloscopes are just rebranded siglent, but when i plug in the oscilloscope into my laptop using a usb a to usb b cable it shows up as an unknown usb device. Where can I find either new firmware or usb drivers for the scope?
