I went to use my Zoom H2 with GarageBand and was dismayed that the low power issue with the USB camera kit still exists in iOS 4.3. Does anyone have a good portable solution to this problem? I have read that powered USB hubs do the job, but I can't find one that has portability, I.e. All the powered hubs require the use of a wall outlet. Any suggestions would be appreciated as I would love to use my H2 with GarageBand.
