I have an issue where when I connect my EVO to my PC and select 'Charge Only', my PC starts charging the phone, but shortly after, it mounts the SD card as a hard drive. I have my EVO set to prompt me when the USB cable is connected. This is a big problem since I cannot charge my phone and listen to music at the same time. This seems to have started occuring after I upgraded to Froyo, but I'm 100 % sure if that is the cause. I have removed any applications that I added recently to see if that is the cause, but no luck. I have also tried different PC's and the same issue. Any ideas???
