Same for me - cardreader not working on HP dv6000 (at least for Memory Stick Pro).
I did not get in working in previous Ubuntu version and the workaround does not work for me on Koala either.
Output of lspci | grep Ricoh is showing:
07:05.0 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 IEEE 1394 Controller
07:05.1 SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter (rev 19)
07:05.2 System peripheral: Ricoh Co Ltd R5C843 MMC Host Controller (rev 0a)
07:05.3 System peripheral: Ricoh Co Ltd R5C592 Memory Stick Bus Host Adapter (rev 05)
07:05.4 System peripheral: Ricoh Co Ltd xD-Picture Card Controller (rev ff)
Output of lspci -vv is attached.
Thanks in advance for any help. And if you need any additional info, please let me know.
