Walter/wayman: According to the email thread linked to earlier in this bug, the SD card reader is using a proprietary protocol that has not been previously reverse engineered. It's not using the usual SCSI-over-USB protocol. So the only way that it will be supported is if the OEM (Acer) provides a Linux driver, or someone with enough knowledge of USB storage drivers sits down, reverse engineers the proprietary protocol, and writes a driver for it.
Alexandre: For the microphone you should open a separate bug. The reason it's not working for you is most likely unrelated to the non-functioning SD card reader.
