Hello,

Tried my USB input for the 1st time last weekend and was wondering about others experience with it. I hooked up my few year old Dell laptop USB 1.1 and RR2150 started to hum. Played a few songs to make sure it did work and it did, but the hum persisted. Even when I powered down the laptop it continued to hum, even on other inputs, until I removed the USB cable.

Should I be looking at the cable to be suspect or the laptop, or god forbid the RR2150

Thanks,

Ranj
