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.
