Hi, I have a similar problem here as well, doesn't udev control the options to the mounted usb device.

I just created a 1G file and copied via terminal to a usb2 drive This was the timing results

real 4m27.082s
user 0m0.006s
sys 0m1.825s

When doing this via Thunar it starts off well and then seems to pause for quite a while.

How do we see the transfer rate in thunar ?

File system on usb device is

Device Boot Start End Blocks Id System
/dev/sdb1 2048 31266815 15632384 b W95 FAT32

Tried a direct write of a 1G file to the usb2 drive and this is the result

1024000000 bytes (1.0 GB) copied, 271.299 s, 3.8 MB/s

4.5 minuses so dd was faster than the copy reported transfer rate is 3.8 MB/s (What are we expecting to achieve though ? / at least to match windoze transfer rate)

Replugged the usb device and it is using ehci

usb 2-1.3: new high-speed USB device number 49 using ehci-pci

Modules report
ehci_hcd 39275 1 ehci_pci

Regards

Yeah, writing to NTFS drives in Linux is really fscking slow. I recommend reformatting the drive to exfat, which does handle large files.

Errr, I don't know exactly how to do that *feels dumb*

Gonna try exfat, thanks

EDIT: btw with noatime it stabilized at 2,1 Mb/s. Kinda sucks but way better than before (less than 1Mb/s).

Try something like

Code:
mkinitrd -c -k 3.10.17 -f ext4 -r /dev/sda4 -m usbhid:ehci-hcd:ehci-pci:ohci-hcd:xhci-hcd:jbd2:mbcache:ext4 -l br-abnt2 -u -o /boot/initrd-3.10.17.gz
My own is a bit more elaborated but this must do as an example.
By the way if the problem is bad module ordering, changing filesystem will not help you.
