@Joseph - I haven't tested that yet as I do not have the older kernels anymore but ...
... I can confirm that it worked few months ago fine before I upgraded the kernel! ... and one more interesting fact about this bug: I cannot mount my USB device when it's plugged in before booting into Ubuntu. But it detects the stick fine when I mount it afterwards, when Ubuntu is booted. Looks like no USB sticks can be detected during the boot process ... ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1490214 Title: Does not detect hotplugged USB device Status in linux package in Ubuntu: Confirmed Bug description: I cannot explain why my Ubuntu 15.04 setup is suddenly not capable of recognizing my USB 8GB stick. It worked yesterday, but not today. Didn't change anything except ran an apt-get upgrade. Hope the attached logs can help you identifying the cause. Thanks!
