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

Right, I've setup USB storage on my 323, plugged in a pen drive, and get these results from hdparm:
Timing buffer-cache reads: 80 MB in 0.51 seconds = 159420 kB/s
Timing buffered disk reads: 2 MB in 3.44 seconds = 594 kB/s
Same thing for my USB hard drive with firmware 1.08. I'm not using a hub.
Why does this happen?
Is there any solution or workaround?
Thanks

Similalr problem someone had about using a 'non-2.0 USB device'. Check dmesg after you 'connect' your usb key and see what it reports when you connect. Make sure it says 'high-speed device'.

For comparison, here's the hdparm on my desktop for the same pendrive:
Timing cached reads: 8496 MB in 2.00 seconds = 4251.36 MB/sec
Timing buffered disk reads: 38 MB in 3.07 seconds = 12.38 MB/sec
Well, looks like it solved itself:
/ # hdparm -tT /dev/sdb
/dev/sdb:
Timing buffer-cache reads: 92 MB in 0.51 seconds = 182515 kB/s
Timing buffered disk reads: 24 MB in 3.00 seconds = 8171 kB/s
/ # hdparm -tT /dev/sdb
/dev/sdb:
Timing buffer-cache reads: 102 MB in 0.51 seconds = 202375 kB/s
Timing buffered disk reads: 29 MB in 3.89 seconds = 7622 kB/s
/ # hdparm -tT /dev/sdb
/dev/sdb:
Timing buffer-cache reads: 112 MB in 0.51 seconds = 222251 kB/s
Timing buffered disk reads: 29 MB in 3.07 seconds = 9667 kB/s
/ # hdparm -tT /dev/sdb
/dev/sdb:
Timing buffer-cache reads: 104 MB in 0.51 seconds = 208305 kB/s
Timing buffered disk reads: 29 MB in 3.09 seconds = 9581 kB/s
Seems like turning it off and on again worked this time!
