if your usb 1.0 is slow, you can buy usb 2.0 cards for like $5.00.
having said that, I own the sandisk m250, but have not had the same issues. sorry i am not really addressing your real ?
Hopefully someone here can be more help than Sandisk. I have the Sansa m260. When I download playlists from Windows Media Player in MPT mode, the player lists the artist and album as "unknown." I currently have the 2.2.1a firmware, and I am reluctant to update because my computer is old and it takes forever to load songs with USB 1. How do I get WMP to load the album/artist, or how do I get the player to "know" what WMP doesn't? Thanks.
