Memory Card access while on usb connection

[krizz]

hello.. Just wanted to know if there's any way of plugging in the phone to USB without losing access to the memory card from the phone..
it would be great if i could drag files to memory card while plugged in to usb and be able to open them from the phone without disconnecting the usb. and plus, if i set a folder/album manually for the pictures and videos from the memory card i wouldnt lose it when i connect to USB.
thanks
