"Were you just using the tablet for internet access to download and update? What brand was it that had the USB stick support? The two I currently have only has SD(micro) and a USB for charging. On the Samsung the USB is proprietary and looks like an ipad connector."
Hi Jon - No, I use my tablet for flight planning also. I have an Asus Transformer 101. For around $30 you can buy an USB stick adapter from Asus that will allow you to plug the USB stick into the tablet's power port. Another point to note - The Android OS down loads all files into its 'DownLoad' folder and gives the files a random name. Before you copy it to the memory stick you must rename the file to 'iFlyUpdatePackage.zip'. - Jim Williams
