lsusb stalls with "UNRECOGNIZED" errors #66

Closed h1z1 closed 6 years ago

h1z1 commented 6 years ago

Not sure if this is a problem upstream or with lsusb. Can confirm at least with the latest git (010) and CentOS release (007).

007: Strange thing is it also appears on virtual hubs: https://gist.github.com/h1z1/d21035ec804de5ad77f9487479e039a4

Looks like an upstream kernel issue, please send this to the linux-usb@vger.kernel.org mailing list. But first make sure you are using the latest kernel version, I have no idea what ancient kernel centos is using, odds are that might be your problem right there, sorry.

Ah. For posterity, the kernel above is 4.16.1-1.el7.elrepo.x86_64 (aka kernel-ml)
