For each operating system the command to use this device was: -netdev user,id=mynet1 -device usb-net,netdev=mynet1. Windows 2000 (qemu-system-i386): - failed to load a driver for the device Windows 7 (qemu-system-x86_64): - Did not find a driver - Followed the directions here: https://developer.toradex.com/knowledge-base/how-to-install-microsoft-rndis-driver-for-windows-7 -- The device failed to start with error 10. - Did see this message in the terminal on the host: usbnet: failed control transaction: request 0x8006 value 0x600 index 0x0 length 0xa Mac OS 10.4.11 (qemu-system-ppc): - It actually works. - did see these messages in the terminal on the host: usbnet: failed control transaction: request 0x2143 value 0x1c index 0x0 length 0x0 usbnet: failed control transaction: request 0x2143 value 0x1e index 0x0 length 0x0 Mac OS 10.8.5 (qemu-system-x86_64): - Fails to obtain IP address using DHCP. - The Network pane does say the device is connected. - A self-assigned IP address is given: 169.254.186.53. -- It still did not work - Did see this message in the terminal of the host: usbnet: failed control transaction: request 0x2143 value 0x1c index 0x0 length 0x0 usbnet: failed control transaction: request 0x2143 value 0x1e index 0x0 length 0x0 Mac OS 10.2.3 (qemu-system-ppc): - Did not appear to detect the USB NIC.
