I got my laptop just a few weeks ago, and it came with Windows 10. Soon afterwards the touch screen started not working, very similar to the posts about the USB device being powered down to save battery (you can find those posts, from Dec 2013 else on this site).
However, I'm on Windows10, with the recent large November public update applied. In device manager there is no 'USB Input Device' listed under Human Interface Devices.
Further: the System's Settings->About panel the OS is reporting under "Pen and Touch" that "No pen or touch input is available for this display".
So, beyond USB power settings, it seems like I'm completely missing the device driver for the touch screen.
I have applied every driver, bios & firmware update that I can find on the Dell support site. Nothing fixed things.
Any hints? Am I looking for a display driver or an input driver or something else?
Same problem here, plus I see an “Unknown USB Device (Device Descriptor Request Failed)” in my device manager constantly appearing and disappearing. Also the touch does not work in the Diagnostic application you can enter via the bios. I don’t know if it should work there, on the 9530 Model it did…
I have the device now for about a week and I think Dell should again be deeply ashamed of what they deliver to their loyal customers.
With the 9530 model they refused to repair the coil whine problem a lot of people complained about. This was really annoying but at least I could work with the device.
The 9550 model has not two issues which really prevent me from doing my work.
As soon as you activate hyper-v the screen starts flickering and the display driver starts crashing.
Touchscreen not working.
We are talking about really expensive hardware here and it’s extremely frustrating when you experience more troubles with a 2.500$ Notebook than you do with 500$ hardware.
And on top of it all they told me today that they could not replace my display because Dell has no replacement parts on stock and they don’t know when they will get them. And that’s exactly what you get when you pay for “Next-Business-Day” “Pro” support.
If the device does not work at the end of the week I will send it back.
Also having the same problem exactly as described, also looking for a fix.
The device I am having this problem on was actually a replacement for another Dell XPS 15 9550 that had coil whine, same model though. I looked through the drivers on the xps 15 that has a working touchscreen, and have found that under HID, there is a listing for "HID-compliant touch screen." On the non-working touchscreen, this entry is completely missing under HID and is replaced by the "USB not found" message as described above.
I tested this on different bioses to see if that was the problem, nothing has helped. Also, all drivers and chipsets are also up to date. Sadly when I got this I set it up, then tried to use the touch screen only to find out it wasn't working. So, I don't exactly know when this occurred.
Wondering what the next step will be. Hopefully Dell can figure something out for us! Really not looking forward to a third return!
Still trying to return! The last two returns I have had have been more defective that the one who's touchscreen isn't working. I've been returning at Microsoft. Honestly, this is just pathetic. All 4 machines I've seen have had some defect. May just return it for good and buy something else.
By the way, it's also a complete joke that Dell employees have purposely not commented on this post. The worst customer service I have ever seen. Anyone here found a fix?
Exactly same thing happen to me. XPS came with Windows 10, the touch screen worked for 2 weeks and then in the middle of the day it stopped working. I tried to reset the windows, unfortunately it didn't help. I am shocked how many laptops are affected and I can not believe that the support is sitting quiet even though more than a month has passed since the initial post...
It's unacceptable that we are getting ignored by the support I think we should make some noise on web (IT portals) about how people buying expensive dell products are being left for them self.
