In the case that the AM335x USB controller is always in host mode and the peripheral IC is powered separately (so negligible current draw), is there any reason using a logic gate to drive USB_VBUS high wouldn't work? What are the benefits of using a power switch IC to drive VBUS? T...

For example, a thumb drive is a basic mass storage application, but the USB class drivers, the SCSI interface and the FAT16 format must all be present for it to function. Currently both the FAT16 and FAT32 file formats are supported in the USB embedded host firmware release versions. If...
