Problem with Kingston MobileLite G3 SD card reader

2013-12-09 Thread Thomas Raschbacher 

Hi.

I recently bought a Kingston MobileLite G3 SD card reader 
(http://www.kingston.com/en/flash/readers#fcr-mlg3).
I now have a problem where it recognises the microSDXC card without any 
problems, but does not recognise the MSPD/SDXC slot at all (on windows I 
get 2 'drives')


the kingston page even lists linux (from 2.6) as supported but well it 
doesn'T seem to really work (any more).


Any ideas what the problem could be?
I can help debug the problem, but I'd need some pointers as to where to 
start, since it's been a while since i've been doing kernel 
hacking/debug ;)


Here are some of the kernel messages I get:

Please post a usbmon trace showing what happens when you plug in the
card reader.  See Documentation/usb/usbmon.txt for instructions.

It looks like the problem is that your kernel was built without the
CONFIG_SCSI_MULTI_LUN option.  If you enable it then everything should
work.

Alan Stern


Ah thanks that solves the problem. Maybe this could/should be mentioned 
in the USB Storage description in the kernel config?
Or maybe even some dummy option as part of the USB Storage config 
section for this which just depends on the CONFIG_SCSI_MULTI_LUN option?
