[patch 1/1] Whitelist-Entry (FORCELUN) for SGS Thomson Microelectronics Cytronix 6in1 card reader in scsi_devinfo.c

[akpm]

From: Hanno Boeck <mail@hboeck.de>

I have a usb-cardreader here that needs some FORCELUN-entries in
scsi_devinfo.c.

lsusb says about the device:

Bus 001 Device 003: ID 0483:1307 SGS Thomson Microelectronics Cytronix 6in1 card reader

Hanno -

Instead of the patch, try running with CONFIG_SCSI_MULTI_LUN enabled.

The problem with these devices is there are so many of them,
(The Fedora kernel had over a dozen additions to the whitelist at one point),
and there were still devices getting reported that weren't detected.
There's no way to stay on top of the amount of these things that are being produced.

There are only two sane solutions that I see
1) Have usb-storage tell the scsi layer "Its a card reader, scan all luns"
or
2) enable scanning of all luns, and blacklist any devices that misbehave.

I chose (2) in the Fedora kernel, and so far, only 1 device got picked up
that needed adding to the blacklist.
