![]() ![]() When the download is complete, open the zip folder that you downloaded and click and drag the Ubuntu folder to your desktop.Note: Ubuntu typically saves files to the Downloads folder that is associated with your user account (for example, ~/Downloads). You can find the part number and product ID on the product packaging. Download the latest drivers from the website ().When the DKMS package is installed, complete the following: Type sudo apt-get install dkms, and then press Enter.On your desktop, click the Ubuntu icon, type terminal, and then press Enter. ![]() To install the DKMS package, complete the following: The book "USB Complete" (4th edition) by Jan Axelson.To install your USB video adapter in Ubuntu 15.0 (kernel 3.16), you need to download the Dynamic Kernel Module Support (DKMS) package and the adapter driver.Vendor id/device id and string that it should report: 1d5c:2000 Fresco Logic Inc. If anyone really wants to see, get in touch. I've got lots of notes and packet captures locally, but it's very disorganized and not worth sharing yet. I'm currently prototyping with libusb, but may need to go a level lower, as the Windows driver for the FL2000 does some strange, somewhat non-compliant things that libusb doesn't easily allow. I've been using USBPCap for capturing the packets from the Windows driver, and Wireshark for analysis and capture on Linux. With this basic understanding, a driver should be entirely possible, and 'simply' needs to be written. Notes on the configurations and pixel format are on the wiki of the fl2000_get_edid github project. I have written a program that can query for EDID ( available on github), and another that can configure the device, bring up the display, and display arbitrary pixels/images. Take a look at this effort for developing a driver. Update: I've decided not to spend more time working on this. I've wanted to learn more about Linux display drivers and USB in general, and this seems like an interesting opportunity for practical reasons and personal ones. Sadly, no Linux driver exists, and there's very little information available. A bit of searching showed that the underlying chip is the Fresco Logic FL2000DX, which appears to allow much better resolution and performance than a (more expensive) DisplayLink. For about $10 one can find something titled like "NEW USB 3.0 to VGA Video Graphic Card Display External Cable Adapter for Win 7/8" on eBay or Aliexpress. I was looking for a USB video card to add to a headless Linux box, and wondered if there were any cheaper alternatives to the DisplayLink devices. ![]()
