He probably means 20-30 M byte/sec.

Hi,
When I scan with my canoscan Lide20, at a resolution or 200 DPI or
more I get:

Hi,
I have a SWEEX 6 in 1 reader/writer . The chip inside is the
carry 5026 (or something like that. I've bolted it back together.
I bought it to be able to read my Sony memory sticks.
When I insert a memory stick and try to read it, however, I seem to
be getting a consistent IO error.

Nope. Sure does sound like it's a mass storage device. And it works

Hi,
I have a Sony F707 digital camera. A day of shooting results in about
95M of pictures. Copying that over to my PC took 25 minutes. Thats
about 63kbytes per second.
As USB can do about 12Mbps, (> 1mbyte per second) and the memory stick
can too, I would like to get about 1Mbyte per second, an
