disabled by hub emi?
Hallo,
i have ubuntu 18.04 on my laptop, 32bit. I bought a usb-Headset from logitech (H650e) which supports linux as operating system. The Heaset ist recognized and works just fine sometimes, mainly if the somputer boots with the headset plugd in but not always. Sometimes the usb-port is disconnected reconnected, but keeps disconnecting again. The dmesg looks like this: usb usb4-port1: disabled by hub (EMI?), re-enabling... Then I get a lot of such messages: usb 4-1: can't read configurations, error -71 usb 4-1: device descriptor read/64, error -71 Thanks in advance for any help! |

Thanks pan64 for your fast reply. It gave me the possibility of learning
something new about my os. I did set my headset successfully as the default device, but this does not seem to change the behaviour. The port still disconnect und reconnect again |

Hallo,
it's my very first time trying to solve a problem by asking direkt in a forum and i am very happy to get help this way. So thanks again and already in advance. I'm still fighting: it looks like, the usb-port is so unstable that each interaction with anything else (plug-in of the power-cable, plug-in of an other usb-device, touching the headset(!)) makes it disconnect. I just realized, that if the laptop is booted with usb-Headset und without power-cable than the headset semms to work fine! Thanks again if you have an idea! |
Try an external usb hub, another usb port, usb extension cable...
It looks like it is is a hardware related issue and cannot be repaired, you need to try to find a working setup. |
