Hello, A while back I asked a bunch of newbie questions and they were answered. Thankyou very much. Gadgetfs seems to be working, I *think*. Since the last time I e-mailed this mailing list, I have decided to use libusb-win32 with gadgetfs. My goal is still to get some simple communcation (read/write) done between the host computer and the device.
I *think* I have almost got it, but am not there yet ... or I may not be where at all ... I really don't know. Any help directing me towards the right direction will be greatly appreciated. Here is what I currently have on the hostside, using libusb-win32 (based on libusb's developers guide @ http://libusb.sourceforge.net/doc/functions.html) : --- briefly ... dev = device_init(); handle = usb_open(dev); // set configuration usb_set_configuration(handle,1); // claim interface usb_claim_interface(handle, 0); // set alternate interface usb_set_altinterface(handle, 0); ---- ... All seems successful for the above though I'm not sure why the '1' in usb_set_configuration(handle,1) works when the bConfigurationValue is 3 on gadgetfs. :-/ Next, I'd like to use libusb's usb_bulk_write() or usb_bulk_read() to read/write to the endpoints but that hasn't been successful so far. Which brings me to my first question : What is the address of my IN/OUT endpoints? How do I go about finding that out? I can see the following files in /dev/gadget : ep2out-bulk ep2in-bulk ep1in-int amd5536udc ... and would love to be able to just write to ep2in-bulk or ep2out-bulk (or whichever). ---- ... For your reference, here is the output on the device that is running the usb.c sample code. I don't know what it's suppose to do next after the CONFIG #3 stage. CONNECT high speed SETUP 80.06 v0300 i0000 255 ... get string 0 lang 0000 SETUP 80.06 v0303 i0409 255 ... get string 3 lang 0409 SETUP 80.06 v0302 i0409 255 ... get string 2 lang 0409 SETUP 80.06 v0300 i0000 255 ... get string 0 lang 0000 SETUP 80.06 v0302 i0409 255 ... get string 2 lang 0409 SETUP 80.06 v0300 i0000 255 ... get string 0 lang 0000 goes on for a while SETUP 00.09 v0003 i0000 0 CONFIG #3 simple_source_thread start 16386 fd 13 simpele_sink_thread start 32771 fd 14 ---- ... All confusion aside, this has been quite interesting and I do hope to learn more. Thankyou.
