Re: Problems with USB hub and Pismo
I would try a different hub, They are usually pretty cheap. Sounds like a power adapter issue. I have a 4 port hub on my pismo and have newer had any issues.

Looks to me as though either the power connector on the board inside the hub is loose, or that the connector on the end of the power cord from the power adapter is bad. The cheapest fix to try is to buy a replacement connector for the cord, install and test. The next would be to pop open the hub and check the security of the connector on the circuit board of the hub. It probably has a three prong attachment to the board which may have broken loose. A light touch with a soldering pencil may do the trick. Ken -- G-Books is sponsored by http://lowendmac.com/ and...
