Hi

I just bought a 'Super Talent Inc.' 64MB flash 'key'. (supposedly USB2.0)

Reads are 'fast enough' but writes are *dire* taking very nearly an *hour* to write 
64MB of data.

the data appears to have written ok, just slowly.

the USB ID is 067b:2517 and there is a controller chip and two samsung flash chips 
inside

Controller has markings:
PL-2515
03272D

Flash chips are:
SAMSUNG: K9F5608UDC-YCB0

the card has been tried on 2.4.20 (i686) and 2.6.0-test9 (i686)

on 2.4.20 it was under the usb-uhci driver
on 2.6.0-test9 it was under the ohci/ehci drivers.

output from /proc/bus/usb/devices shows it has some kind of 'embedded hub' whatever 
thats used for.
