Thank you for the rapid response. I will try and investigate getting answers to some of your points but I'm a little new to Solaris so I'll need some time. Glancing at the configure output, it looks like it built against v0.1.7 of libusb (yes i think that is derived from the one you mention),
checking for libusb version via pkg-config... 0.1.7 found checking for libusb cflags... checking for libusb ldflags... -lusb checking for usb.h... yes checking for usb_init... yes checking for usb_detach_kernel_driver_np... no I will first investigate how to set the debug level.
