I use fedora 12 on a dell inspiron 1545 laptop. (2.6.31.12-174.2.22.fc12.x86_64).
i have a external usb hd and i can't make it connect like a usb 2.0 device.
this device is ntfs format
I check if the device is using ehci (dmesg after i plug the device)
[root@localhost ~]# dmesg | grep USB
usb 2-2: new high speed USB device using ehci_hcd and address 2
I check if this device is connected on a usb 2.0
[root@localhost ~]# lsusb
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 015: ID 0471:2021 Philips
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
I mount the device with this options:
/dev/sdc1 on /media/hd_backup type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096)
but when i use cp, mv or rsync, the max speed i get is max 6MB/s (a lot 800kB/s).
If i use this device on Windows (tested with Vista and Seven), i get much high transfer rate.
I read about sync and async options, but if i put sync or async on fstab, it does not alter the transfer rate.
Is this the normal upload transfer rate? I am doing something wrong?
