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): ... 00:1c.0 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 1 (rev 02) 00:1c.1 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 2 (rev 02) 00:1c.2 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 3 (rev 02) 00:1c.3 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 4 (rev 02) ... 04:00.0 System peripheral: JMicron Technologies, Inc. Device 2382 04:00.2 SD Host controller: JMicron Technologies, Inc. Device 2381 04:00.3 System peripheral: JMicron Technologies, Inc. Device 2383 04:00.4 System peripheral: JMicron Technologies, Inc. Device 2384

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.
