Hi all...

I have an Aspire One, and the JMicron SD Card reader is hidden from  
sysfs
space, it only shows if I do an lspci -H1 (direct hardware access):

lspci -M:

...
00: Primary host bus
	1e.0 Bridge to 05-05
	1c.3 Bridge to 04-04
	1c.2 Bridge to 03-03
	1c.1 Bridge to 02-02
	1c.0 Bridge to 01-01
...

If I load the driver (sdhci), it does not detect anything. It looks like
it is hidden/hung after one of the pci bridges, how can I make this  
device
visible for the driver ?

Thanks.
