Nothing fancy. :) A 23XX card in it's place works just fine. I believe, due to the architecture difference between the 4G/8G and 2G cards that it just doesn't work right now. The 4G/8G architecture does nothing in target mode except DMA the incoming data. the 2G cards do some things for the driver. I was hoping that someone has some patches in their trees just lying around that I could look over and test for 4G target mode support. :) -- Sean Bruno MiraLink Corporation 6015 NE 80th Ave, Ste 100 Portland, OR 97218 Phone 503-621-5143 Fax 503-621-5199 MSN: sbruno@miralink.com Google: seanwbruno@gmail.com Yahoo: sean_bruno@yahoo.com
