Title:
197b:2381 [Acer Aspire 5930] JMicron internal card reader recognizes
SD only when inserted at startup
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
My Acer Aspire 5930G has an internal 5-in-1 card reader. Testing with
an SD card (no alternative media available), the reader is only listed
by lspci if the SD card is present in the reader at boot time. Boot
time dmesg attached.
Now if an SD card was present at boot time, I can remove the SD, and
dmesg will report
[ 164.613053] mmc0: card db81 removed
If I reinsert it, dmesg will say
[ 179.271670] mmc0: new SD card at address db81
[ 179.276522] mmcblk0: mmc0:db81 SD512 500224KiB
[ 179.276522] mmcblk0: p1
and gnome will display an SD drive icon on my desktop and ask if any
files should be imported.
But nothing of all that happens if the SD card was not already in the card reader at boot time!
