Does the attached patch for FreeBSD's libusb solve your issue?
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)
Can you run "ldd" on your binaries to see they really are using the
libusb you installed?
