Public bug reported: the only way to use usb 2.0 hard disks and flash drives / cards is typing: cd /sys/bus/pci/drivers/ehci_hcd/, sudo sh -c 'find ./ -name "0000:00:*" -print| sed "s/\.\///">unbind'
looks like a bug that was present in previous versions sometimes the usb drives are seen and automounted and sometimes they aren't. If they are, any attempt to copy files to them generates errors ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: linux-image-3.2.0-27-generic-pae 3.2.0-27.43 ProcVersionSignature: Ubuntu 3.2.0-27.43-generic-pae 3.2.21 Uname: Linux 3.2.0-27-generic-pae i686 NonfreeKernelModules: nvidia AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
