Hey guys, I've got radioSHARK recently (it've been used by my dad before). I connected it to my iMac's keyboard USB port and it woked fine. After a few days of use I needed this port for another device, so I disconnected it and left it in this state for over 1.5 weeks, but now when I try to connect it again it says that "USB device is drawing too much power. Deactivating USB port". Well and this port on keyboard is deactivated, however I re-activated it by unplugging and plugging in keyboard. Then I tried to connect radioSHARK to one of USB 2 ports on the iMac itself. No wornings now, blue light on the SHARK is ON, but radio is not playing. Any ideas??
