I would be glad to hear if anyone can offer insight into this problem.
I have a small mining setup with three BFL Jalapenos attached to a Pogoplug host.
As long as each Jalapeno is plugged directly into its own USB port on the Pogoplug all goes successfully.
The Pogoplug has only three available USB ports, so I would like to attach the Jalapenos to a USB hub to free up two ports. However, when I do this cgminer produces "hex2bin scan failed" error messages. In the example below, only one BAJ is connected to the hub. cgminer appears to partially see the Jalapeno (in that it knows it is a Jalapeno), but produces error messages when trying to actually use it.

I have consulted the forums. The only thread I saw appearing relevant indicated that if cgminer is not running as root, the Jalapenos should be in udev.d as owned by the plugdev group. cgminer is running as root (see below), but I applied the fix anyway, rebooted and the problem persists.
http://i58.tinypic.com/52yqsw.gifThere are no error messages when each Jalapeno is plugged into its own port.
I've tried several different USB hubs, USB 1.1, USB 2.0, powered and unpowered.
