I have an identical issue as the op, although I am running Kubuntu 8.04. My setup is quite similar to the op's - Sempron 3200+ on an Asus K7N2 mobo with NVidea graphics.
Since the kernel update to 2.6.24-22-generic in my case, I either have to plug USB devices into the hub before booting, or else "sudo lsusb" to get them automounted. The printer is plugged into the hub, and I use it for thumbdrives etc. Here's the output from lsusb with printer switched on and a thumbdrive plugged in (and mounted, after I did lsusb): Bus 007 Device 001: ID 0000:0000 Bus 006 Device 001: ID 0000:0000 Bus 005 Device 001: ID 0000:0000 Bus 004 Device 005: ID 04a9:10a2 Canon, Inc. Bus 004 Device 004: ID 0781:5406 SanDisk Corp. Cruzer Micro 4GB Flash Drive Bus 004 Device 003: ID 05e3:0606 Genesys Logic, Inc. D-Link DUB-H4 USB 2.0 Hub Bus 004 Device 001: ID 0000:0000 Bus 003 Device 001: ID 0000:0000 Bus 002 Device 001: ID 0000:0000 Bus 001 Device 003: ID 041e:401e Creative Technology, Ltd WebCam NX Pro Bus 001 Device 001: ID 0000:0000 The webcam is plugged into a port on the motherboard (it only has 2 ports, hence my use of the hub). uname -a gives: Linux ourbox 2.6.24-22-generic #1 SMP Mon Nov 24 18:32:42 UTC 2008 i686 GNU/Linux I have attached dmesg output and the other outputs requested. Towards the end of dmesg can be seen where I plugged in the thumbdrive and did lsusb. Then I switched on the printer and did lsusb again. I hope this helps resolve some other people's issues...just received a new Gigabyte GA-MA78GM-S2H mobo with Athlon X2 4850e. Will no longer need the hub since this new kit has plenty of ports on it. ** Attachment added: "lspci-vvnn.log" http://launchpadlibrarian.net/21002807/lspci-vvnn.log -- no auto-mount for USB-stick through USB-hub https://bugs.launchpad.net/bugs/285006 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
