Only if your devices uses in kernel drivers. If you need to use a binary-only driver supplied by the manufacturer of the device, it will not work. Note: Some ARM-systems (Raspberry Pi for example) don't provide enough (read: only about 200mW and not the full 500mW) power on their on-board USB ports. Devices which want to draw more power than provided will fail to work and in most cases hard reset the ARM-system. Usage of a seperate powered USB hub is advised. Grüße, Sven. -- Sigmentation fault.
