roland, i think the timeouts are due to a usb initialization problem, which is in turn due to differences between how 'reset' works in different versions of libusb. from the "Found station at bus= device=" i would guess that you are running libusb 1.0, but could you post the exact versions of pyusb and libusb on your ubuntu system? i have been testing the wmr300 driver on ubuntu 14.04.1 with kernel 3.19.0-32-generic on x86_64 with these usb versions: python-usb 0.4.3-1 libusb-1.0-0 1.0.17-1 libusb-0.1-4 0.1.12-23.3 m -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
