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 00:28:41 kentang kernel: [90532.492624] usb 4-1.2: New USB device
found, idVendor=0bda, idProduct=8176
Sep 10 00:28:41 kentang kernel: [90532.492627] usb 4-1.2: New USB device

Sep 10 00:28:41 kentang kernel: [90532.492629] usb 4-1.2: Manufacturer:

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.
