Hi Devid, Thanks for the reply.
Yes, I'm using 2.4 Kernel version and I have some dependencies on that, it's difficult to change to 2.6 kernel immediately. Is there any alternative way to avoid this problem using 2.4 kernel?

Or at least, there's an inconsistency when _entering_ the "OFF" state from "ON" ... it disconnects in one case, not the other. It should be both cases, or neither. > Same scenario I tried it in windows and its working fine. But in Linux > it's giving problem. Does Linux 2.6.12-rc3 behave better? You were using an old 2.4 kernel, that's known to have quirks with disconnect behavior. - Dave ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
