Hi Larry,

For comparison, what does your device report when plugged in? My device 
reports this:

Sep 10 00:28:41 kentang kernel: [90532.399226] usb 4-1.2: new high-speed 
USB device number 26 using ehci-pci

Sep 10 00:28:42 kentang kernel: [90532.581776] rtl8192cu: Board Type 0

Also what type of USB port are you using? I'm plugged direct (no hub) 
into a ehci-pci port on a laptop if that makes a difference to power?


ATB,

Mark.
