You all need to buy an App in the market called "USB Mount All v.1.3". It formats the tablets to accept all USB drives including FAT32. I found it researching the same questions you guys had and installed it. Works perfect.
I am new to these tablets. I have a A500 and want to use a flash drive for work items. How do you know if they work or don't? I can not figure out where to go to see whats on the drive. help.
Any idea if it will work with flash media and a card reader? I'd like to be able to view photos on SD and CF cards, which means attaching a USB card reader, which SHOULD be possible on the Acer USB host port, but I'd like to know before I make a decision on buying one.
Everything I stick on the Acer works. Just purchased at CompUSA a real tiny PNY 4GB Attache Micro Swivel usb for $8.99. Works perfectly. And since it is only an inch or less in size, it is awesomely convenient.
Go to the market and down load ES File Explorer. https://market.android.com/details?id=com.estrongs.android.pop&feature=search_result See their website here. Its an awesome app and it lets you see the content of your entire Tablet and Flash Drive and move things from place to place. It will also browse your local area network and let you move files from your computer to your tablet and vise versa. Play with it for a few minutes to see how it works. Don't go deleting files with it.
Almost any Flash drive will work. Its rare to find one that doesn't. Just avoid those with the so-called "security switches". Start with any you have laying around.
When you plug in the flash drive ES File Explorer will show you the contents of the drive.
(Local tab, press the microSD symbol (first symbol on the second line of icons)
Then scroll down to /mnt and tap it. Then select USB_storage and the content of your Flash Drive will appear. Tap any file and it will open, as long as Android knows what it is. (docs, jpgs mp3s etc).
But Android will find stuff on that drive with other programs as well.
Use the Gallery app that is pre-installed. It will find all the pictures that are on the flash drive.
Use the Music app. It will show you all the music that is on the flash drive.
It takes these apps a brief few minutes to scan the drive and find all the files, so if they don't
show immediately give it 3 minutes.
