I’m having trouble getting my NEC UPD720200 USB 3.0 controller to function properly on Ubuntu 12.04. Is there a way to resolve this issue? Any suggestions or solutions would be greatly appreciated.

I’ve been pulling my hair out trying to get my NEC UPD720200 USB 3.0 controller to work on Ubuntu 12.04. It seems I’m stuck in a loop of frustration! I mean, I got excited thinking I could finally utilize those USB 3.0 ports for faster data transfer, but here I am, unable to even get the controller recognized.

I’ve done some digging online and found a few threads discussing this controller, but none of the suggested solutions seem to be doing the trick for me. I thought it might be a driver issue, so I checked the System Settings and made sure everything was up to date. Also, I tried plugging the controller into different USB ports, you know, just in case it was one of those ‘only this port works’ deals. No luck.

Then I moved on to trying some terminal commands because, apparently, that’s where all the real magic happens in Linux, right? I executed a couple of commands like `lsusb` to see if the controller even showed up, and to my surprise, it did! But despite that, nothing happens when I try to plug in a USB 3.0 device. It just refuses to recognize it.

I even took it a step further and looked into manually loading drivers or maybe even installing a newer version of the kernel, as I’ve read that could help. But honestly, I’m not too comfortable with diving too deep into kernel stuff, especially with the risk of messing up my system.

Has anyone else run into this issue? Is there a simple solution I might be overlooking? I’d appreciate any tips on what I could try next. It’s becoming quite the headache, and I’d love to get past this hurdle—those faster speeds seem so enticing! If someone could walk me through the process or let me know if there’s an alternate approach, that would be fantastic. Thanks in advance!

    1. Ubuntu 12.04 USB 3.0 Controller Help

      Stuck with NEC UPD720200 on Ubuntu 12.04

      Sounds like you’re hitting quite the wall with that USB controller! I totally get the frustration—USB 3.0 ports are like the pot of gold at the end of the rainbow, and they should just work, right?

      So, you’ve run `lsusb` and it shows the controller, which is a good sign. It means your system is at least seeing the hardware. But yeah, not being able to use it is a bummer. Here are a few things you might want to try:

      • Check dmesg logs: After you plug in a USB 3.0 device, run dmesg | tail in the terminal. This can show you any error messages or issues related to USB devices.
      • Update your kernel: I know you mentioned being a bit hesitant about kernel updates, but newer kernels might have better support for your controller. You could try updating to a more recent kernel using something like sudo apt-get install linux-generic-lts-raring (you might want to check which version is suitable for your needs).
      • Try a different USB device: Just to make sure it’s not a device issue, can you test with a different USB 3.0 device? Sometimes device compatibility gets weird.
      • Install missing drivers: You might want to check if you need any additional drivers. Sometimes they don’t come included with the default installation, so keeping your system updated with sudo apt-get update and sudo apt-get upgrade could help.
      • Using the USB 2.0 ports: While it’s not the same speed, just to get things working temporarily, see if USB devices at least work in your USB 2.0 ports. This way, you can confirm it’s specifically the USB 3.0 that’s being stubborn.

      If all else fails, you might consider posting on forums like Ask Ubuntu or the Ubuntu forums with the details you already have. The community can be super helpful, and someone might have a solution just waiting to be shared!

      Good luck! Hopefully, you’ll have those USB 3.0 speeds running soon!



    2. It sounds like you’re in a frustrating situation with your NEC UPD720200 USB 3.0 controller on Ubuntu 12.04. Since you confirmed that the controller is recognized by using the `lsusb` command, it’s likely that the controller itself is functioning, but there could be issues with the USB 3.0 drivers or kernel version. First, you should check if the necessary modules are loaded by running `lsmod | grep xhci`. This should show you if the xHCI (USB 3.0 controller driver) is active. If it’s not listed, it may imply that the driver isn’t loading properly, which could explain your connectivity issues with USB 3.0 devices. If it’s not loaded, you could try loading it manually with `sudo modprobe xhci_hcd`, and see if that resolves the issue.

      If the module is loaded and you’re still having issues, it’s possible that updating your kernel could help, especially if you encounter compatibility problems with older systems like Ubuntu 12.04. While updating involves some risks, you can look for a newer kernel series that maintains compatibility with your system. One option is to use the Ubuntu Hardware Enablement Stack (HWE), which may provide newer kernels and drivers that include the necessary support for your USB 3.0 controller. Ensure that you back up your data before proceeding with any major changes, and consider running the update in a virtual machine or dual-boot setup to mitigate risks. If you’re still stuck after these steps, consider reaching out to the Linux community forums with detailed logs from `dmesg` and any relevant error messages, as other users may have encountered and resolved similar issues.
