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.
I already modified the "sd" driver not to probe for capacity if
the sense code is NOT_READY/NO_MEDIA_PRESENT as well as UNIT_ATTENTION/
NO_MEDIA_PRESENT: My device returns that code on the "sda" device,
and then "does funny things" on the read capacity.
So now I get a bit further, but I don't understand why the usb-storage
reports "OK" on the ALLOW_MEDIUM_REMOVAL, and then the IO layer
reports something like "I/O error"

This is the output of me trying to read the 1k block at 1Mbyte off
an 8Mbyte memory stick.
The vendor/device ID is 07cc/0201. I'm running Linux-2.4.20-rc2.
Any help appreciated....
Roger.
