Per your suggestion, I contacted Corinex and received this reply to my hardware question:
If I already have a LAN operating with a Linksys 10/100 Etherfast Bridge connected to my internet-connected Host PC running Windows XP Home, and if I purchase your Corinex Powernet USB Adapter and connect it to my laptop running Red Hat Linux 9, will it communicate with my network via the home
powerline? Thank You.
The answer is: No.
Our adapters and Linksys bridges would work together without problems (as HomePlug compatible devices), but unfortunatelly neither we, neither other manufacturer don't support Linux on USB adapters. The reason is that the chipset manufacturer (Intellon) has not published documentation for Linux driver on their USB chipset. If you want to use Linux Notebook and Powerline, I advice you to use our Ethernet Adapters. Otherwise I suggest you to contact Intellon (www.intellon.com
) to increase pressure on them to publish details on USB Linux driver, as they fear for not enough demand.
It would appear they too do not have linux USB support as proported.
