disabled by hub emi?
by flori75 from LinuxQuestions.org on (#55MPT)
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!
