I’ve has a Lascar Electronics EL-USB-3 Voltage Data Logger for over 20 years and it works fine with no issues connecting to EasyLog software.

When I bought a replacement laptop, I downloaded from Lanscar Electronics the latest USB software, version 7.7.0.0, however, I ran into connectivity issues:

I went through the trouble shooting guide after changing the Tekcell SB-AA02 battery, but still no luck, even though the device was recognised in Device Manager.

I spoke to Lascar technical support who suggested the EL-USB-3 was faulty and needed replacement, this seemed odd as it was the software causing the issue, not the logger.

As luck would have it, I had a zip download from 2010 of version 5.53 and tried this on my Windows 11 laptop and it worked!

It seems as a rule of thumb that the latest all black loggers will work on the new software, whereas, the legacy silver loggers will need earlier software to work.
