Unfortunately no one can be told what fun_plug is - you have to see it for yourself.

I get this output on dmesg :
usb 1-1: new full speed USB device using ehci_platform and address 2
hub 1-1:1.0: USB hub found
hub 1-1:1.0: 4 ports detected
usb 1-1.3: new full speed USB device using ehci_platform and address 3
usb 1-1.3: not running at top speed; connect to a high speed hub
The key is plugged into a usb2.0 hub (as I want to use printer sharing and the usb for ffp at the same time).
hdparm -tT outputs this:
/dev/sdb1:
Timing buffer-cache reads: 110 MB in 0.51 seconds = 219647 kB/s
Timing buffered disk reads: 4 MB in 3.82 seconds = 1070 kB/s
So it is clearly not running at full speed... When I plug the key in by itself it runs at full speed.
Any ideas on how to get it running at full speed through the hub?

What is considered 'high speed' in the hdparm command?
I have a USB hub and am running a usb stick and a printer and I'm getting:
/dev/sdc1:
Timing buffer-cache reads: 98 MB in 0.51 seconds = 194881 kB/s
Timing buffered disk reads: 25 MB in 3.12 seconds = 8195 kB/s
Are you referring to the disk reads?
P.S. I did notice that when I plug the USB key into port 2 (second furthest from the main USB cord) and then plug the printer into port one and reboot the device, it doesn't recognize ffp off the USB. But if I put the USB in port 1, it works fine, almost like it looks to port one first, then looks to HD_a2 and THEN loads port 2 if present. Not sure if this matters, but maybe try swapping the devices?
Thanks

I'll have a go at swapping and see what happens. I'd just like a disk read speed nearer 10/15/20 MB/s

I believe those messages are self explanatory ..
usb 1-1.3: not running at top speed; connect to a high speed hub
And yes, I did note that you said the key was plugged into a 2.0 hub - I've experienced similar problems with 2.0 hubs, that would not allow a 2.0 device to connect at 2.0 speeds.

I wondered if there would be some magic trick lol.
I guess that will teach me for buying shitty budget hubs.

This made me think it may be software related: http://ocaoimh.ie/ubuntu-linux-slow-external-usb-drive/
The 'fixes' on there don't work though as the 323 complains that the files cannot be found...

uuuuhhh - yeah - it probably is - at least I though so too, so I wasted a lot of time cutting hubs open, determining what chipset was used, tracking down drivers (for Windows in my case) and generally futzing around, and them I figured my time was worth more than that.
