I'm looking at the existing support for using the Beaglebone Black board as a USB host. The board is based on an AM335x SOC, whose USB module is built around the Mentor musbmhdrc USB OTG controller. I looked at the corresponding driver (sys/dev/usb/controller/musb_otg.c) and saw a comment indicating that the current implementation only supports Device Side Mode, while the commit history (and the code itself) shows that there's at least a basic Host side support. Has anyone tested this driver and knows whether the host side is functional= ? --=20 Martin Galvan Software Engineer Taller Technologies Argentina San Lorenzo 47, 3rd Floor, Office 5 C=C3=B3rdoba, Argentina Phone: 54 351 4217888 / +54 351 4218211
