The problem is that my X5 with firmware 2.0 installed will not recognize any of the USB flash drives that I have connected to it with the provided OTG cable. I remove the SD cards, attach the flash drive via the OTG cable, go to formatting within the X5 and it prompts me to insert a TF card. It doesn't see the flash drive at all. I have tried three different ones all from reputable well known manufacturers and nothing. Has anyone actually gotten OTG to work with a USB 2.0 flash drive of any capacity? I have used my PC to format the flash drives to FAT32 but the X5 still does not even recognize that there is a device connected to it. A bit of a bummer actually as the one card had about 60GB of music on it before I formatted it on my PC. Now I have to re-transfer all of that music back to it. Not fun!
I have a 32GB USB flash drive that I used for a bit, but I had to format it with FAT32 from the command line in Windows 7 as there is no option for FAT32 in the gui formatter.
Go to the command prompt in Windows 7 & use the following command:
format /FS:FAT32 X:
Be sure to change X to whatever drive letter your computer assigns to the flash drive.
I have no problem formatting USB flash drives to FAT32 in Windows 7 Home Premium. I will insert the flash drive into a USB port on my PC afterwards go into the properties of the flash drive and it indicates that it is formatted to FAT32. A Lexor 64GB flash drive that I purchased recently was already formatted to FAT32 at the time of purchase.
