Re: XPS 8910, Rear USB 2.0 ports not working?

The driver is listed with Chipset in the Category filter. If I check the 'show drivers for your Service Tag' checkbox only three updates are listed, but if I uncheck the checkbox five updates, including the update you mentioned shows up.

I don't use SupportAssist. I prefer to decide for myself what updates to install, especially after I read what happened to some folks who got automatic BIOS updates.

Thanks for pinging your Dell tech contact.

My Dell tech contact said "_____"  about searching by Service Tag!   :Surprise: :Stickouttongue: :Wink: :Angel:

So just decide if you want to run the USB firmware update or not. That has to be your decision. And -obviously- I don't know if it will fix the existing USB2 problems, regardless of whether it does the things listed in the description of the firmware update.

Post back and let us know what you decide and if the firmware update helps with USB2, if you decide to run it.

Thanks, Ron. I happy using the powered USB hub, so I will pass on the firmware update. Seems to me the ASMedia controller, which is what this firmware update is for, supports USB 3.1 whereas USB 2. & USB 3.0 is supported by the Intel Z170 chipset.

As long as the ASMedia controller meets Intel's USB controller standards and doesn't do anything that might interfere with USB2.

ASMedia claimed it's "...backward compatible with current USB2.0 standard and complies with Intel's eXtensible Host Controller Interface (xHCI)..."

But maybe the ASMedia firmware on the chip installed in the XPS 8910 wasn't fully compatible with USB2 and that caused USB2 failures on the XPS 8910?  I honestly don't know.

And it's your PC...

Re: XPS 8910, Rear USB 2.0 ports not working?

I don't think I've done SupportAssist or Dell Updates lately, just Microsoft Updates. Is there a way of telling if the USB firmware update has been installed? (My apologies if one of the other messages in this thread tells how to do that.)

You can follow the instructions (step 4) in this article to check the firmware version: https://www.dell.com/support/article/us/en/19/sln307910/using-available-utilities-to-check-hardware-... I followed the instructions but I have no way of knowing if the results reflect the actual firmware version. Here are my results: PCI\VEN_1B21&DEV_1242&SUBSYS_072A1028&REV_00 PCI\VEN_1B21&DEV_1242&SUBSYS_072A1028 PCI\VEN_1B21&DEV_1242&CC_0C0330 PCI\VEN_1B21&DEV_1242&CC_0C03 A search of the first Hardware ID does identify this as ASMedia USB 3.1 eXtensible Host Controller drivers / Dell XPS 8910.

Re: XPS 8910, Rear USB 2.0 ports not working?

I presume (my assumption!) if you run the firmware update, it will either install or tell you it's the same version that's currently installed...

Since the update was only released ~3 weeks ago, I tend to doubt you already have it.  And I don't know if firmware updates are ever released via Windows Update.

If you choose to run the update, read/follow the directions on Dell's page carefully. Make sure all apps are closed, and it would be a good idea to temporarily disable whichever anti-malware suite you use (eg, Windows Defender, Norton, McAfee) before running the update, and re-enable the suite after the update has been done.

And each of you has to decide for yourself whether to run the update or not...

Re: XPS 8910, Rear USB 2.0 ports not working?

The USB 2.0 port that my keyboard was plugged into failed again two days ago. I plugged the keyboard into one of the rear USB 3 ports and that didn't work. I tried a different rear USB 3 port, and that worked. This morning I tried the powered USB 2.0 hub that I had bought, and that worked with the USB 2.0 port after turning on the hub and restarting the computer.

I had this problem also. Both USB 2.0 ports failed with the keyboard and mouse that came with my 8910. I moved them to USB 3.0 ports and some of those failed. I switched to a different keyboard and a Logitech wireless mouse with the USB 3.0 ports, and those continued to work. After reading some of these threads the other day, I decided to order a powered USB 2.0 hub to see if that would work. It arrived today. Before installing it, I decided to test the USB 2.0 ports again. I don't think I had tested the keyboard by hitting F12 and going into BIOS Setup, so I decided to connect the keyboard to one of the USB 2.0 ports and do that. Lo and behold, it worked! Then I started up Windows 10 and that worked, also! I tested the keyboard with the other USB 2.0 port and that worked, too. Then I moved the dongle for the wireless mouse to one of the USB 2.0 ports. Both keyboard and mouse are now working with Windows 10 with the USB 2.0 ports, without having to use a USB hub. There must have been some recent software changes with Windows Update that fixed the problem with the USB ports on my computer. I tried some suggested software fixes a few months ago and those did not help. I will see if the ports continue to work. I think the keyboard that came with the 8910 was causing problems.

Re: XPS 8910, Rear USB 2.0 ports not working?

If I recall correctly with my XPS 8910 the USB 2.0 port would fail intermittently with the keyboard. To keep the failure from being permanent I always connect via a powered USB hub.

Re: XPS 8910, Rear USB 2.0 ports not working?

This worked in the past on some older desktop PC models to "retrain" the USB power controller, but I don't know if it will work on the XPS 8910.

Connect the externally powered USB hub to a rear USB2 port and its power adapter to the wall. Connect both mouse and keyboard to the hub. Boot the PC to desktop and confirm mouse and keyboard work. Then reboot 2-3 times more and confirm each time that mouse and keyboard are working.

Then with PC on and booted up, disconnect keyboard from the hub without disconnecting the powered hub from PC or from the power outlet. Connect keyboard directly to a different rear USB2 port, leaving the hub still connected (and powered) with mouse attached to it. Reboot 2-3 times and test keyboard after each reboot.

If keyboard is still working after last reboot, disconnect mouse from hub without disconnecting the powered hub from PC or from the power outlet. Connect mouse to another USB2 port and reboot 2-3 times. Test both keyboard and mouse after each reboot.

If both still work, disconnect the hub from rear of PC while PC and hub are both still powered on, and reboot 2-3 times, testing each time.

As I said, on some older models this seemed to solve the problem permanently but YRMV.  And if this sounds painful, or doesn't work, just keep using the powered hub. :Wink:
