To test the built library, build the example application and run it. $ cd examples && make $ su -c './listdevs' Now, here is the problem: When I run 'listdevs' with no USB device connected to the box I get: libusb: 0.000000 debug [libusb_init] libusb-1.0.9 libusb: 1.870000 debug [usbi_add_pollfd] add fd 4 events 1 libusb: 1.870000 debug [libusb_init] created default context libusb: 1.880000 debug [libusb_get_device_list] libusb: 1.880000 debug [obsd_get_device_list] libusb: 1.910000 debug [libusb_exit] libusb: 1.910000 debug [libusb_exit] destroying default context libusb: 1.920000 debug [usbi_remove_pollfd] remove fd 4 And thus no device is listed, as expected. However, if I plug in any USB device I get the following message after the first (libusb_init) line: WARNING: 1 error while detecting hardware; check system log. It means that this message is produced by the 'rump_init' function. The other debug messages are the same, and thus no device is listed --- what's not right. Do you have any idea on what's going on? Any points to facts, procedures, concepts or documentation will be highly appreciated.
I suggest you export RUMP_VERBOSE=2 to get verbose output from the Rump kernel. OTOH I think this part of your patch: + #define RUMP_SYS_OPEN + #define RUMP_SYS_CLOSE + #define RUMP_SYS_IOCTL + #define RUMP_SYS_READWRITE is a bit dangerous. It would break any (current or future) usage of open() / close() / etc in that file which is not related to USB device nodes. Best regards -- Robert Millan
