Crash in Ubuntu 20.04

[tkircher]

I'm using the ALFA AWUS036NHA, Ubuntu 20.04 with kernel 5.4.0-26-generic x86_64

ID 0cf3:9271 Qualcomm Atheros Communications AR9271 802.11n

It takes a couple of tries to get it to recognize the device. It also eventually works. However, it repeats this error over and over in the system log every couple of seconds:

Maybe someone knows what's happening here.

I wonder if this is related:

https://github.com/kuoruan/lede/blob/master/target/linux/generic/pending-4.9/821-usb-Remove-annoying-warning-about-bogus-URB.patch

[olerem]

The patch is just removing warning. Removing sanity checks is not a solution.

Probably this is related: "It takes a couple of tries to get it to recognize the device." Did you tried to use different cable? Something shorter?

Thanks for the response. I dug out a shorter cable, and no errors. Closing.
