Hi @Philip,
Thanks for backing Joulescope and welcome to the forum!
Depending upon which updates and software your Windows 7 system has applied, it may or may not support automatic WCID Device driver installation. Your report of trying multiple times only to have it work later is odd. On failures, was Joulescope showing up in device manager under “Other devices” with the yellow exclamation point (I assume that this is what you mean by “anonymous USB device”)?
I put together an INF that forces Win 7 to recognize your Joulescope. Here are the steps:
- Download the device INF and the bootloader INF to a {path}. Make sure that your browser saves these as “.inf” and not “.inf.txt” with a hidden extension.
- Connect Joulescope to the host PC
- Start Device Manager: Start, type “Device Manager”, press Enter
- Right click on Joulescope, which should be listed under “Other devices”
- Click “Update Driver Software…”
- Click “Browse my computer for driver software”
- Enter your {path}, click Next
- Click “Install this driver software anyway”
- Should see “Windows has successfully updated your driver software”
- Click Close
Does this fix your issue?
If you attempt a firmware upgrade, you will need to follow similar steps to install the INF for the joulescope bootloader.
