I have a CF WiFi (Planex GW-CF11X recommended on Sharp Zaurus website) for my C1k.
It works well under Sharp original ROM (Japanese) using "prism3" driver provided on Sharp Zaurus websit. When connecting it blinks. I can use "Wellenreiter" meanwhile.
It doesn't work under Trisoft ROM (English) using the same driver. it doesn't have any reaction (not blinking) when connecting.
I do not know what is going on? Trisoft ROM should be similar with the original one. Does anyone has the similar experience? Someone has an idea of this?
