Thanks for confirming that.
This seems like a different issue from the one you originally reported. The first time, the updater could detect the device is a Cure 2 but could not communicate with it. Now it seems the connection was unhandled.
We can continue looking into it on our side. It might help to get the full logs, starting at the time you run the updater.
Will do. I’ll send the logs in a PM as this thread doesn’t need that cluttering it up.
@smerret Oh, please make sure you update to the latest PreForm 3.55.1
Here’s a relevant part of the release notes:
Fixed issues with printer USB connectivity due to Another version of PreForm is using this printer and/or Unavailable Printer Detected errors
I am experiencing the same thing. FormWashCureUpdater.exe will close down after I plug in USB. If I don’t plug in USB it will sit and wait. So something is triggering it to close once USB is connected to Cure/Computer.
Hi all, can you please confirm using Windows Device manager’s Driver by type feature that the formlabs usb drivers are installed on this machine? The msi package could install successfully but the drivers may still have issues.
Thank you for this guidance. I have the following.
I note that you highlight the Form Cure L V2 (I think) but I have the Cure V2. Not sure if that makes a difference. Both drivers of the kind your arrow points to seem to be installed on my machine/account.
My default view shows the Cure V2 as “other devices”
Hi there, looks like the device is not picking up the right driver (hence the 
icon). We managed to reproduce a similar issue in-house, we are still investigating the root cause.
Sorry for the inconvenience, we will report back as soon as we find a fix or a workaround.
The workaround from @jesus.rubio to manually assign the libusbK driver seems to have been successful. Thanks
