Hello. Does anyone know what may cause such a strange behavior of usb system (version 2.0): reading speed (from flash disk) ~5 MB/s writing speed (to flash disk) ~50 kB/s? And how this problem can be fixed? Thanks. Roma.

Data transfer to a USB Memory Stick is terribly slow by default, as the sync option to mount is enabled. To fix this, create a file called 90-storage-nosync.fdi with the following contents <?xml version="1.0" encoding="ISO-8859-1"?> <deviceinfo version="0.2"> <device> <!-- disable sync for mount --> <match key="block.is_volume" bool="true"> <match key="volume.fsusage" string="filesystem"> <match key="@info.parent:storage.bus" string="usb"> <merge key="volume.policy.mount_option.sync" type="bool">false</merge> </match> </match> </match> </device> </deviceinfo> Copy this file as below and restart the HAL. cp 90-storage-nosync.fdi /usr/share/hal/fdi/policy/20thirdparty rchal restart
Hi. Thanks a lot. It works. However, it appears that I've got more than one problem with USB. When I try to "Safely Remove" flash-drive I receive this kind of error: Title: Error - kio_media_mounthelper Contents: umount: /media/usbdisk missing from fstab (and you are not root) Please check if disk is inserted properly. What do I do? I go for console (as myself, not root). Type: eject /media/usbdisk. Voila. :-\ This kind of "Safely Remove" worries me, though. Is it "safe"? Nevertheless, how can I fix this kio_media_mounthelper situation? Thanks, Roma.
