[Bug 542022] Re: ao532h with unr 9.10 card reader non functional

[Gary Peck]

this bug affects me as well on a Gateway LT2104u netbook running 10.04
netbook edition. as far as i know, the LT2104u is just a re-branded
version of the Acer AO532h.

it looks like the card reader actually shows up as a usb device, not a
pci device. when i insert an sd card into the card reader, lsusb shows
the following new device (which is not present when no memory card is
inserted):

Bus 001 Device 004: ID 0cf2:6250 ENE Technology, Inc.

when i remove the memory card, the above usb device goes away.
/var/log/syslog only contains the following events from the time the
memory card is inserted to when it's removed:

Jul  8 18:44:07 tweety kernel: [ 4474.384674] usb 1-5: new high speed USB device using ehci_hcd and address 3
Jul  8 18:44:07 tweety kernel: [ 4474.517824] usb 1-5: configuration #1 chosen from 1 choice
Jul  8 18:44:26 tweety kernel: [ 4493.382658] usb 1-5: USB disconnect, address 3

i will not have a chance to test the latest ubuntu cd image or the
upstream kernel for 2 months. but i wanted to add the above information
in case it is useful. i'm also including "lsusb -v" output for this
device:
