Now I'm looking for a switch to enable UAS. As far as I understand the code in tcm_usb_gadget.c, BOT is the hard-coded default, right? In usbg_setup you test for USBG_IS_BOT and bail out with an error if the flag is not set. Would this be the place to add another if-then-else branch and call usbg_uas_setup? Although that particular function is missing right now.
The device side should be good. On the host side there is no exclude. That means if usb-storage grabs the device first, it will use it. What should work is to rmmod usb-storage and uas and then modprobe uas. The uas driver on host should then notice the uas altsetting on the gadget and enable it.
Anyway, good work. I am really excited to see the usb3380 be able to transfer data at a rate closer to the advertised 350 MB/s. So far, I've only achieved about 35 MB/s. Let me know, if I can help you test the tcm_usb_gadget with a real UDC.
Okay.
Kind regards, Thomas.
