I have a Canon PowerShot SX210IS & a HP Photosmart C5180 All-in-one. The memory card from the camera is not recognized by the printer nor does it show on the "Device Menu" of My Computer (Windows 7). Have no trouble with any of my other SD cards from any other cameras (I have another Canon as well). I can download from the camera with a USB but not directly from the card. ???????????????????????????????
