usb device descriptor read/64, error -71

**Syphotellion** · January 24th, 2022

This seems like a fairly common problem, but none of the solutions I have looked at have yet helped me.

I originally posted this as an "answer" at Ask Ubuntu, since I don't have enough reputation for a "comment". My answer has since been deleted, and I don't see any better way to get a discussion going about what may or may not be different than my issue.

Some possible solutions that haven't yet worked for me.

`use_both_schemas=yes` from e.g. https://urukrama.wordpress.com/2009/...ised-error-71/
1. I don't know, but I suspect that since I see both `read/64` and `read/8`, that it's already trying both?
"unplug everything and power off" from e.g. https://paulphilippov.com/articles/h...-address-error
1. being a laptop, this was more difficult for me. but it still didn't help
downgrade the linux kernel.
1. this didn't help me
downgrade other recent package updates.
1. this may be the next thing i try.
I contacted Dell support, trying to verify that there was not an actual hardware problem.the laptop is only a few months old, so it is still covered by "basic" warranty. We ran a hardware diagnostic (Pre-Boot System Assessment) which passed, suggesting that there are no hardware issues.

Apparently I don't have enough reputation to comment, but I have a similar issue that just started this week.

Code:

In my case, the USB device that has stopped working is my laptop camera. It was working at least as of 10 January:

Code:

Jan 10 09:06:45 alan-gaming kernel: [    1.447941] usb 3-5: new high-speed USB device number 3 using xhci_hcd

I suspect one of these updates from the 17th or 18th may be involved?

But I've tried downgrading my Kernel (to 5.11.0-43-generic), and that hasn't seemed to help.

There is a lot of _old_ advice about this issue.

`use_both_schemas=yes` from e.g. https://urukrama.wordpress.com/2009/...ised-error-71/
- I don't know, but I suspect that since I see both `read/64` and `read/8`, that it's already trying both?
"unplug everything and power off" from e.g. https://paulphilippov.com/articles/h...-address-error
- this didn't help. being a laptop, this may be harder? I have not yet tried opening up the laptop to disconnect the battery and/or resetting the CMOS.

What else can we try?

i was able to disable the webcam in the BIOS, and the system started up with no errors -- and no issues / slowness with discovering other USB devices.
after going back into the BIOS and re-enabling the webcam, the system resumed reporting the same USB errors. so the above was not a great long term fix -- i would like to be able to use my webcam.

Hello,

I have the same problem on my Dell Precision 3541 on Ubuntu 21.10. I have disabled the webcam in BIOS but this is not a long term fix like you said. The `uname -r` command output is 5.13.0-28-generic. My colleagues have the same computers with the same version and have no problems.

Just wait for an update that can solve the problem ... or a magic trick !
