I have just patched, build and installed libusb. I removed the libusb_open() / libusb_close() calls from usb_get_port_path() in libsigrok and tested. https://github.com/sigrokproject/libsigrok/blob/a9010323ddf4e479663e871386c05db05ea3522e/src/usb.c#L473-L491 Unfortunately, the problem is still present. On the first enumeration, libusb_get_port_numbers() returns 3 and the firmware is send to the device successfully. Then, when lbsigrok attempt to re-enumerate devices, libusb_get_port_numbers() returns -12 (LIBUSB_ERROR_NOT_SUPPORTED). I am sure that the firmware is sent successfully because usbconfig(8) shows the following when I plug the device: | ugen0.10: <vendor 0x04b4 product 0x8613> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (100mA) and after the enumeration failure, I can see this instead: | ugen0.10: <sigrok fx2lafw> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (100mA) Regards, Romain -- Romain Tartière <romain@blogreen.org> http://romain.blogreen.org/ pgp: 8234 9A78 E7C0 B807 0B59 80FF BA4D 1D95 5112 336F (ID: 0x5112336F) (plain text =non-HTML= PGP/GPG encrypted/signed e-mail much appreciated) [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- iQGzBAEBCAAdFiEEgjSaeOfAuAcLWYD/uk0dlVESM28FAlp4ed0ACgkQuk0dlVES M28CXAv/SZXf0ptR0RaORq8VDtnWaKWNd+AZ9FMinW0O61t1a2WpLhmC1OKK8iyZ 6xMevEmdFSYpq34kIwxwMm9XMcFj7bp82zHRmbxyDb/XHTHw6ZJhfAfkS5xhxCjX s2oKRfUENSxKG9c7UCpsibn1BxeX0dfH3bDguA551InihPTpGR3+rhzTwd5KDhsf CZvmpVwgtQhtJs0UaVgDAwANHiitP66J7cKpKAGYzuJqTH4cYlBqsg3EV4YOi324 bHyP85AQ86W4e18qypHAGxoizIafZLM6g1Rzi8hSeSIy4/QGNekAV+cm6v48aNdS PNTffC8/jCNGK5db9zrvymrLtLZMi3udEpNn9cyGmpTV1EfbPNSEYXoN5Lu/EZYO FbijZ9n2oOZoVz4fwFLXYXcS55x8CGVTUe5indeQOTeVnlQ32ajgsoZsPQLEEep6 v2akTtdunWqvvkb5DlD8TMC/S1sJ9X3PXriWoc9VseyIjG21wbcA5pYSH24lotSV /kgj/myK =ZxpZ -----END PGP SIGNATURE-----
