But when i type usb_add gadget:1, the qemu says in the QEMU monitor: (qemu) Could not remove USB device '0.5' Why? Seems to me like he gets some errors and want trys an automatic usb_remove... > >Additionally, there are three lines output from QEMU's stdout/err: > >s3c_udc_handle_packet: EP0 overrun > >pcf_write: automatic Fast-charge enabled > >s3c_udc_handle_packet: EP0 overrun I killed the qemu much fuster this time an i could see this messages, too: [...] gadget_read: event error: 4 gadget_ep_setup: endpoint configuration failed: -1 gadget_read: event error: 4 [...] gadget_read: event error: 4 gadget_ep_setup: endpoint configuration failed: -1 gadget_read: event error: 4 [...] gadget_read: event error: 4 gadget_read: event error: 51 gadget_read: event error: 4 [...] gadget_read: event error: 4 gadget_read: event error: 51 gadget_read: event error: 4 [...] gadget_read: event error: 4 s3c_udc_handle_packet: EP0 overrun gadget_read: event error: 51 gadget_read: event error: 51 gadget_read: event error: 4 pcf_write: automatic Fast-charge enabled. gadget_read: event error: 51 gadget_read: event error: 51 gadget_read: event error: 4 [...] gadget_read: event error: 4 gadget_read: event error: 51 gadget_read: event error: 4 gadget_read: event error: 4 s3c_udc_handle_packet: EP0 overrun gadget_read: event error: 51 gadget_read: event error: 51 gadget_read: event error: 51 gadget_read: event error: 51 gadget_respond: packet write error: 3 gadget_read: event error: 4 [...] gadget_read: event error: 4 [...] > >ifconfig usb0 inet 192.168.0.200 netmask 255.255.255.0 I haven't a usb0 device! :-( SIOCSIFADDR: Kein passendes Gerät gefunden usb0: ERROR while getting interface flags: Kein passendes Gerät gefunden SIOCSIFNETMASK: Kein passendes Gerät gefunden > It also says can't find gadgetfs if you don't have it specified in > the config.h file before compiling qemu. Wow ... it's not ... at first i thought this could it be, but then i looked in the file ../config-host.h wich is included by config.h. In ../config-host.h is "#define CONFIG_GADGETFS 1". Or do you mean that i have to specify the directory /dev/gadget? How can i do this? Tim Niemeyer
