Peter Clare Posted April 23, 2021 Share Posted April 23, 2021 I have been using my Sprog2 for many years : plug in and the com4 appears in device manages and all has worked OK.. Yesterday, plugged it in and no com4...therefore it will not work. I updated the sprog software and java software, but still no joy.. Anyone any thoughts ?

Peter Clare Posted April 24, 2021 Author Share Posted April 24, 2021 I tried the Sprog 2 on an older windows 10 drive..that worked ok...so nothing wrong with the sprog unit or USB cable: comes up on com3.. Back on the new windows 10 drive [latest version] the other drive was an older version. The com3 is grayed out ?? compared with com1..?? The unit has appeared under other devices.. The pc dings when the unit is plugged in.. I am lost for an answer..possibly something to do with USB drivers ? But there again it did work..

Nigelcliffe Posted April 24, 2021 Share Posted April 24, 2021 I'd hazard a guess that you need to re-install the drivers for the Sprog. There are instructions on the Sprog website about how to do it, and also how to identify which version of the Sprog you have (because the driver situation is different for different hardware). If the older hardware it can be a faff, to disable "driver signing", do the installation, then driver signing is re-enabled (automatically). The Com port number allocated is semi-random; Windows just issues them as it sees new devices. So whilst you may have COM3, you might find another Windows which has allocated COM3 to something else, and uses a different number. - Nigel Link to post Share on other sites More sharing options...
Peter Clare Posted April 25, 2021 Author Share Posted April 25, 2021 Nigel..thanks for the information..It got me thinking.. A few months ago I was given a Sprog 3, so I tried that..and hay-presto it worked.. Over the months I must have downloaded the Sprog 3 software, instead of the Sprog 2 software..Looks like this was causing the error.. regards Peter Clare Link to post Share on other sites More sharing options...

(Also with the Lenz LI-USB, which uses the same chip) Edited April 25, 2021 by melmerby Link to post Share on other sites More sharing options...

You can do the two-step installation after disabling signing, no need to do it twice. Link to post Share on other sites More sharing options...

Ah! Didn't realise that. Haven't done it for a while. Link to post Share on other sites More sharing options...
