Hi,
I bought a new backup disk which turned out to be UAS capable,
but when I plugged it in I got an order 7 page allocation failure.
My hunch is that the .can_queue = 65536 in drivers/usb/storage/uas.c
is much too large. Maybe 256 would be a pratical value that matches
the capabilities of existi

Hi Felipe,
a USB soundcard in fullspeed mode works correctly
when directly connected to a musb OTG port in host mode
on an AM335x SoC, but produces garbled audio output
when connected via a hub. usbmon shows that in both
cases URBs with typically 5 isoc frames of 192 bytes
length are queued. The

Hi,
I'm testing dwc3 with g_zero and noticed that errors
seem to stick even after SET_CONFIGURATION/SET_INTERFACE.
In f_sourcesink.c, check_read_data() calls usb_ep_set_halt()
if the data does not match the expected values, and
sourcesink_set_alt() indirectly calls usb_ep_disable()
and usb_ep_ena
