Hi all, We're facing a problem while trying to emulate a USB-ether device in software (using usb/gadget/ether.c). We're connecting the tablet to a linux PC as host. The device enumeration happens successfully. After this the host side driver sends some vendor specific commands on the control EP (these commands are for setting up the device which we're trying to emulate). After enumeration the following EPs are setup (apart from control EP0): EP1 IN/OUT- Bulk EP2 IN - INTERRUPT The host then polls the interrupt EP and checks for link status from the device. This is where we get stuck, i.e we see the host putting a interrupt IN packet on EP2, but there's no indication of it coming to the device (tablet). We've put debugs in the musb/tusb core to see if the peripheral controller is at least getting an interrupt. Debugs in tusb6010.c::tusb_interrupt() show that we are _always_ getting interrupts for EP0 and never for any other EP. The musb->int_tx value is always 1 ! This is strange because usbmon debugs on the host show that the host has polled the interrupt EP, but somehow the peripheral controller is not getting any interrupt for this EP. I'm not very experienced with USB device controllers, so any pointers on this will really help.
