the way I would do it is to plug my USB drive into my computer, have my Torch connected in "mass storage mode" and then drag and drop from my USB drive to my Torch music folder
now just to figure how to setup for mass storage mode and I will be set thanks
when you plug your BB into your PC, the device should ask you if you want to 'sync media', 'mass storage', or 'charge only'
you want mass storage... your device's internal memory, and microSD card(if applicable) will show up in "my computer" as additional drives... drag your music from your thumb drive to your bb device, or bb media card, and violla
