Yes, i change the name string to "ep1" for both endpoints [ Before that, it is ep-a, ep-b, and bulk-out endpoint auto-configured to 2 ]. In ep_matches(), the isdigit(ep->name[2]) if-condition is fulfilled. In fsg_bind(), after the usb_ep_autoconfig() for bulk-out returns, the fsg_fs_bulk_out_desc.bEndpointAddress is 1. >> however, i only see one SCSI_INQUIRY command being sent out, and it is >> not received by the gadget device. > > There could be other reasons for this, like an incorrect data toggle > value.

After i do insmod usbmon, g_file_storage, and my UDC driver, the "lsusb -v" shows nothing. Should my UDC driver provide the info in /sys/bus/usb folder? # ls /sys/bus/usb/ devices drivers_autoprobe uevent drivers drivers_probe # lsusb -v # Thanks, victor -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
