It was working OK on my hx4700 running 3.0.1. But with 3.1.0 (and at least 3.2.0-rc2 and 3.2.0-rc3) I now see the following warning: pxa27x-udc pxa27x-udc: ep0:handle_ep0:should never get in WAIT_ACK_SET_CONF_INTERF state here!!! I can still seemingly connect to the hx4700 from my linux host using cu(1) as before, but no characters get transferred in either direction. ^ permalink raw reply [flat|nested] 3+ messages in thread

Assuming you're using the serial gadget (g_serial) on the hx4700x in "non-ACM mode", there's a submitted fix for that in [1].
