Trouble with EV2300 Driver

Hello,

we are succesfully using the EV2300 to check and set up Battery packs (with a BQ2080/85) for years. Now we have trouble with the USB driver of the EV2300 (perhaps since the last windows security update, but not sure). Reinstallation of the driver fails. I already tried some newer downloads, also the Vista driver for the EV2300. But without succes. We tried this on several PCs under windows 2000 and XP without any succes.

Does anybody know this problem? Is there a fix for this problem available?

Greetings,

Birger Neumann
