Here I am :-) actually, I'm using a TUSB7320 (just two less ports away from 7340), plus Linux Kernel 2.6.37 with TI proprietary patches (I'm working on a board hosting a TI81XX system-on-chip) here's what happens: - hotplugging USB2/USB3 peripherals is ineffective, the only way to have a gadget seen is plug it BEFORE powering on - moving files from a gadget (a WD My Passport 500GB HD Drive) to central mass storage works, moving the opposite way don't ends up in a filesystem error, and the device gets unmounted - same things as before if I plug the same HD through an USB2 hub do you know if TI is supporting linux directly on these devices? and of course, Sarah, do you have some hint?
