More comments coming from DELL: "Yesterday, a new Dell internal document was created which contained a temporary work around to downgrade the camera firmware to 1.0 ( the file RomainDurritcague shared ). This internal document is about to be deleted as this fix wasn't meant to be shared yet. The document was released prematurely. I've asked RomainDurritcague to delete the post which contains the file in question. The firmware downgrade is a downgrade in features. We don't like to downgrade our customers. Dell is working to release an OS patch that will allow Ubuntu owners to utilize the camera with UVC 1.50. The patch is scheduled to be released on 5/11. That's all the detail I have on the patch at this time. More to come.
