This problem (hackrf_open() failed: HACKRF_ERROR_LIBUSB (-1000)) shows when you have no rights to access the HW, it is necessary to set udev rules as here ( https://github.com/mossmann/hackrf/wiki/FAQ ) but if you are using one hackrf that is not your problem. I have received that error too when using two hackrf with osmocon source/sink, one is ercogniced an the other isn't (using hackrf=0 and hackrf=1), but using the serialnumber (hackrf=000000000000000071c469c825671743)
hackrf_info returns (now just one hack plugged) andromeda:/etc/udev/rules.d # hackrf_info hackrf_info version: 2017.02.1 libhackrf version: 2017.02.1 (0.5) Found HackRF Index: 0 Serial number: 000000000000000071c469c825671743 Board ID Number: 2 (HackRF One) Firmware Version: 2017.02.1 (API:1.02) Part ID Number: 0xa000cb3c 0x00494758 andromeda:/etc/udev/rules.d # So, yes, it works with FW 2017.02.1. regards El 03/05/17 a las 16:57, Pierre AVITAL escribió: > Hello, > > I have been trying to use 2 HackRFs to try to get a full duplex > working as well as to test performance requirements for multiple > HackRF handling. > > But I can't get both to function at the same time, as it appears > nothing HackRF related will work once one of them is in use. > As far as I've tested, once a hackrf is used in any way (my method was > using osmosdr's osmocom_fft), any use of libhackrf (even hackrf_info) > will result in the following : > hackrf_open() failed: HACKRF_ERROR_LIBUSB (-1000) > > Using dmesg, I've found that both hackrf's have the same serial, but > that being 0, I doubt any hackrfs have different serials, so I don't > think that's the problem. > I've tried reinstalling libusb and libhackrf to no avail. > > Any ideas ? > > Thanks in advance for your help, > Pierre. > > > _______________________________________________ > HackRF-dev mailing list > [email protected] > https://pairlist9.pair.net/mailman/listinfo/hackrf-dev
