I'd love for my GP2X to connect via USB even if it is slower than a card reader.
It's a pain in the bum to keep powering off, ejecting, powering back on. I feel like an Ariston.
I eventually got XP to see the GP2X good enough for me to transfer data to the card by
1. disabling the USB2 Enhance Host Controller within XP Device manager
2. formatting the (128MB) SD card (£10 from Tesco BTW), with FAT32 File System (FS), via XP disc Manager. Disc Manager only saw the card but no partition or FS (even though the GP2X could read the files from it).
However, the GP2X could then only see the files and folders in Gibberish.
I eventually had to format the SD card in my digital camera for the GP2X to see the contents of the card again but then XP now only sees the card as a drive with no partition or FS?
And round and round in circles I go.
