Testing with a Kingston DataTraveler on 2.6.27-14-generic x86_64 Ubuntu 9.04.

But yesterday a friend used his iPod to copy 3.9 GiBi of data from my hard drive... And was blazing fast! I didn't have the time at the moment to do tests with his hardware, but later I noticed that the iPod had two different lines in dmesg: [81601.496620] usbcore: registered new interface driver usb-storage [81601.496716] USB Mass Storage support registered. ** Attachment added: "dmesg from Pen drive." http://launchpadlibrarian.net/26989331/dmesg.txt -- file transfers on USB disk are very slow https://bugs.launchpad.net/bugs/197762 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
