It needs to be disabled by disabling 'swig', which is also non-obvious as --help does not list --disable-swig as an option. ./configure --disable-swig &amp;&amp; su make install appears to works just fine. ________________________________ From: Charles Lepple &lt;clepple&lt; at &gt;ghz.cc&gt; To: Robert Warner &lt;rwarner1&lt; at &gt;yahoo.com&gt; Cc: "libhid-discuss&lt; at &gt;lists.alioth.debian.org" &lt;libhid-discuss&lt; at &gt;lists.alioth.debian.org&gt; Sent: Thursday, May 10, 2012 5:20 AM Subject: Re: [libhid-discuss] Configuration issue on SuSE 11.3 On May 9, 2012, at 5:39 PM, Robert Warner wrote: If you installed Python via RPM, is python-devel installed?

If possible, get a known-good hardware (eg: the dev kits from Microchip) and then use the known-good Microchip USB firmware framework to get familiar with the stack first. </pre> Xiaofan Chen 2011-11-16T11:49:56 http://permalink.gmane.org/gmane.comp.lib.libhid.general/845 <pre>Well I had tried out the bootloader and I get the same problem. It writes to it as it says Querying Chip. but then it gets disconnected when trying to write from the chip. No difference in the problem of either program. I was told that D+ was the write to chip line and D- was the Read from chip line.  checked out the connections they seemed to be good, but will debug the lines later have to go somewhere. Wondering what could be the deal on this chip and bootloader if it has a not read option or should it be readable from the get go? ________________________________ From: Daniel Yount &lt;factorf2&lt; at &gt;yahoo.com&gt; To: Xiaofan Chen &lt;xiaofanc&lt; at &gt;gmail.com&gt; Cc: "libhid-discuss&lt; at &gt;lists.alioth.debian.org" &lt;libhid-discuss&lt; at &gt;lists.alioth.debian.org&gt; Sent: Tuesday, November 15, 2011 8:44 AM Subject: Re: [libhid-discuss] USB libhid is writing to PIC but errors out reading from it.

(Windows apparently masks this difference when reading or writing to HID interfaces - it uses an interrupt endpoint if available, otherwise it issues a request on EP0.) From below, you only have "EP 1 IN" (plus the always-present EP0 IN/ OUT). You probably want to use hid_set_output_report(): http://libhid.alioth.debian.org/doc/hid__exchange_8c.html#7eb62286840ff33db4f68d58682bc4ad And the path is going to look like { 0xFF000001, 0xFF000002 } (depth 2 since there are two elements). See the comments in the example source code (or the archives of this list) for the derivation. An alternate way of approaching this is to use one of the tools which converts USBSnoop (or similar) log files to sequences of direct libusb calls. Since your HID device is simply using the HID transport layer to pass 8-byte messages around, you might find it easier to just use libusb directly.

USB has the notion of Control endpoints (EP0 IN and OUT), and also Interrupt endpoints. Not all devices have interrupt endpoints, but if you post the output of 'lsusb -v' (run as root, preferably after something like libhid has detached the kernel HID driver), we can see which endpoints are available. Ah, I think I see what's going on: you passed endpoint 0 to hid_interrupt_write() - it should be 1 or higher. Again, lsusb output will pin this down. _______________________________________________ libhid-discuss mailing list libhid-discuss&lt; at &gt;lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/libhid-discuss http://libhid.alioth.debian.org/ </pre> Charles Lepple 2011-09-09T02:22:57 http://permalink.gmane.org/gmane.comp.lib.libhid.general/834 <pre>Hi, Apologies for what might be a basic libhid question. I'm running Ubuntu, and using libhid via Python to communicate with a HID device (and have used 'lsusb' to glean all the details of the device). I've started out with the example code here: http://anonscm.debian.org/viewvc/libhid/trunk/swig/test_libhid.py .I added the vendor and product ID and the example code itself worked FINE. I then added some code to the example. From the 'snooping' on the communication with the device under Windows it needs a control message with an initialisation string to initialise the device, which I thought would be: INIT_SEQ='0x20 0x00 0x08 0x01 0x00 0x00 0x00 0x00' ret = hid_interrupt_write(hid, 0, INIT_SEQ, 8) if ret != HID_RET_SUCCESS: log_error("hid_set_output_report", ret) But when I added the above spinet to the example and run it I get: (ALL messages fine up to here) --------------------- NOTICE: hid_force_open(): successfully opened USB device 006/002[0].
