I have recently installed rockbox on my 8 gig Sansa 280e and all my music/plugins seem to be in working order, except that whenever i try to connect my mp3 player to my computer, for some reason nothing happens anymore. I am getting a picture of a USB cable on the sansa and I assume that means its connected on that end, but no folder appears in my computer (also I get no error messages or anything that indicates even a problematic USB connection). The patcher is saying something about UMS mode, but i have searched the manual and the settings and cannot seem to find it. I would appreciate information on how to fix this problem, or direction as to what specific part of the manual I should look at. Thank you in advance.
