Angelo, thanks for the update. So we can get a better picture of the scenario, could you please plug your Android phone in, execute the following at the Terminal, and post it to this report: lsusb
As well, does this problem occur with other usb devices or just the Android? ** No longer affects: linux ** Also affects: linux Importance: Undecided Status: New ** Description changed: file copy dialog closes but file isn't actually written on the drive. I manually remove the usb drive and when i plug it in again, file system becomes "read-only". I'm using a PCI USB 2.0 HUB and there is no problem with other external drives using different file systems such as NTFS or ext4. Kernel 3.2.0-20.32 wasn't affected. - Problem does not exist in 3.3.0-999_3.3.0-999.201203310435 + Problem still exists in 3.3.0-999_3.3.0-999.201203310435 ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: linux-image-3.2.0-21-generic 3.2.0-21.34 ProcVersionSignature: Ubuntu 3.2.0-21.34-generic 3.2.13 Uname: Linux 3.2.0-21-generic i686 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
