Hi guys, I'm getting a weird behavior with g_mass_storage which I'm yet to verify if it's a g_mass_storage bug on XHCI bug. So far it points to g_mass_storage. Below you can see a commented set of trace data (see the 2-patch series I just sent): [...] > file-storage-1252 [003] ...1 254.793660: usb_ep_queue: ep1out: length 0/16384 sgs 0/0 stream 0 zsI status -115 --> 0 > file-storage-1252 [003] ...1 254.793669: usb_ep_queue: ep1out: length 0/16384 sgs 0/0 stream 0 zsI status -115 --> 0 > irq/17-dwc3-1253 [000] d..1 254.793717: usb_gadget_giveback_request: ep1out: length 16384/16384 sgs 0/0 stream 0 zsI status 0 --> 0 > irq/17-dwc3-1253 [000] d..1 254.793725: usb_gadget_giveback_request: ep1out: length 16384/16384 sgs 0/0 stream 0 zsI status 0 --> 0 > file-storage-1252 [003] ...1 254.793728: usb_ep_queue: ep1out: length 0/16384 sgs 0/0 stream 0 zsI status -115 --> 0 > file-storage-1252 [003] ...1 254.793741: usb_ep_queue: ep1out: length 0/16384 sgs 0/0 stream 0 zsI status -115 --> 0 > irq/17-dwc3-1253 [000] d..1 254.793792: usb_gadget_giveback_request: ep1out: length 16384/16384 sgs 0/0 stream 0 zsI status 0 --> 0 > irq/17-dwc3-1253 [000] d..1 254.793799: usb_gadget_giveback_request: ep1out: length 16384/16384 sgs 0/0 stream 0 zsI status 0 --> 0 > file-storage-1252 [003] ...1 254.793807: usb_ep_queue: ep1out: length 0/16384 sgs 0/0 stream 0 zsI status -115 --> 0 > file-storage-1252 [003] ...1 254.793815: usb_ep_queue: ep1out: length 0/16384 sgs 0/0 stream 0 zsI status -115 --> 0 > irq/17-dwc3-1253 [000] d..1 254.793863: usb_gadget_giveback_request: ep1out: length 16384/16384 sgs 0/0 stream 0 zsI status 0 --> 0 > irq/17-dwc3-1253 [000] d..1 254.793869: usb_gadget_giveback_request: ep1out: length 16384/16384 sgs 0/0 stream 0 zsI status 0 --> 0 > file-storage-1252 [003] ...1 254.793877: usb_ep_queue: ep1out: length 0/16384 sgs 0/0 stream 0 zsI status -115 --> 0 > file-storage-1252 [003] ...1 254.793885: usb_ep_queue: ep1out: length 0/16384 sgs 0/0 stream 0 zsI status -115 --> 0 > irq/17-dwc3-1253 [000] d..1 254.793934: usb_gadget_giveback_request: ep1out: length 16384/16384 sgs 0/0 stream 0 zsI status 0 --> 0 > irq/17-dwc3-1253 [000] d..1 254.793941: usb_gadget_giveback_request: ep1out: length 16384/16384 sgs 0/0 stream 0 zsI status 0 --> 0 > file-storage-1252 [003] ...1 254.793950: usb_ep_queue: ep1out: length 0/16384 sgs 0/0 stream 0 zsI status -115 --> 0 > irq/17-dwc3-1253 [000] d..1 254.794007: usb_gadget_giveback_request: ep1out: length 16384/16384 sgs 0/0 stream 0 zsI status 0 --> 0 > irq/17-dwc3-1253 [000] d..1 254.794014: usb_gadget_giveback_request: ep1out: length 16384/16384 sgs 0/0 stream 0 zsI status 0 --> 0 > irq/17-dwc3-1253 [000] d..1 254.794079: usb_gadget_giveback_request: ep1out: length 16384/16384 sgs 0/0 stream 0 zsI status 0 --> 0 > file-storage-1252 [003] ...1 254.794092: usb_ep_queue: ep1in: length 0/13 sgs 0/0 stream 0 zsI status -115 --> 0 > file-storage-1252 [003] ...1 254.794096: usb_ep_queue: ep1out: length 0/1024 sgs 0/0 stream 0 zsI status -115 --> 0 > irq/17-dwc3-1253 [000] d..1 254.794159: usb_gadget_giveback_request: ep1in: length 13/13 sgs 0/0 stream 0 zsI status 0 --> 0 finished our transfer.

For some reason, g_mass_storage didn't start queueing transfers. Any idea off the top of your heads? The remaining is just the gadget processing USB Reset. I can gather more data if you want.
