I inserted the flash stick, activated the desktop Storage Media icon, went to the inserted flash stick, right-clicked Properties, and only a normal two-tab dialogue box came up, i.e., only a General and a Permissions tab. Didn't see a Mounting thingy.

Have you mounted the USB stick with sync or flushed IO? You can find this under: Storage media-> right click on the USB stick-> properties-> mounting.

Using 12.2_x86 with KDE3, and getting 100k/sec transferring (copying) files from my HDD over a USB2 port to a USB2 flash stick. The same file transfer in Mint14_x86 Cinnamon over the same port to the same device is about 6 mb/s, and in openSUSE 12.2_x86 with Cinamon DM gives the same 6mb/sec transfer. All are separate physical partitions, not VMs.

On the same PC using Windows 7_x64, over the same port to the same device, the write speed is also 6mb/s or more. Makes no difference to all of the results if the transfer originates from an ext4 or ntfs partition, or if the flash drive is formatted fat32 or ntfs, in both Windows and Linux. The files I tested are 600mb to 1.5 gig in size.

I was surprised about the transfer speed in KDE3, as I assumed all the USB functionality came from the kernel and not the desktop manager.

Any thoughts?

Erik, Could be the same issue I had with external USB disk since 12.1. Check the file /opt/kde3/share/config/udisks-glue.conf Try removing automount_options = { sync, noatime } In my case it helped.

YES! I removed the line in my file, logged out/in, and tried the test transfer again. Right away it started at 6mb/s, ranging up to 7, a real difference from the previous, abysmal 100k/s. Thanks muchly, Mark!

Ilya, it's obvious that something in a KDE3 implementation installs this /opt/kde3/share/config/udisks-glue.conf file. Can you amend it to delete the offending line, if that's the "proper" fix for slow USB transfer speeds?

It seems that the 6 Mb/s speed that you see in onther software is not the real device tranfer rate but the transfer rate to the cache. When sync option is on, you see the real transfer rate. Note that even if you see the 6 Mb/s transfer rate reported, you in reality cannot unplug the device before all the data is written with real speed. -- To unsubscribe, e-mail: opensuse-kde3+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kde3+owner@opensuse.org

Using both Konquerer, and the cp command in a terminal, before making Mark's suggested change to udisks-glue.conf, I cut short the test transfer of a 700 mb (movie) file after 4 minutes, and the filesize of the infomation that had been transferred during that 4 minutes (at 100kb/s) was only 27.6 mb.

After applying Mark's "fix", the transfer took only about 1:20 minutes for all 700 mb, I immediately played the start and end of the movie off the flash drive after the "copying" window closed at 1:20, and the file manager showed the full 700 mb file size on the flash drive.

So I don't know about cache vs real transfer to the device, but Mark's line deletion really works!

With hal-enabled kde3 the configuration of the mount options sync and flush are exposed to the user interface. Do you have a working "safely remove" of the device without hal-enabled kde3? -- To unsubscribe, e-mail: opensuse-kde3+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kde3+owner@opensuse.org

Now, if I could just figure out why all my 12.2 installs don't recognize my USB3 ports at all, while Win7 and Mint 14 Cinnamon do! Is it a 12.2 kernel thingy that will be addressed in 12.3? -- To unsubscribe, e-mail: opensuse-kde3+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kde3+owner@opensuse.org
