Good day.
Recently I purchased the USB to TTL serial cable (http://www.adafruit.com/products/954). After unpacking it I plugged to USB HUB not connecting it to a board. The USB HUB gone down immediately. When I unplugged the cable, USB HUB restored.
Is it a problem in a cable or is it me who connects it wrong?
Thank you very much in advance,
USB to TTL serial cable problem.

Yes, the HUB is powered. The power supply provides up to 800mA.

First I tried the TTL pins disconnected, then I tried TX, RX, GND pins connected. Result is the same. I have bad hunch that the chip just short circuits USP bower pins.
