Hello all
I develop wifi support over USB Bus over mobile type device. It is to
connect with ralink 8572 device, I do not think it is problem with
this driver as i check with another device ( not mobile device). I
work on 2.6.28, my mobile device is embedded and i cannot change OS
with latest kernel.
I am able to ping the network through wifi interface, but when i start
data communicate. I am being disconnect from USB bus
In hub.c
USB_PORT_STAT_C_OVERCURRENT
if (portchange & USB_PORT_STAT_C_OVERCURRENT) {
dev_err (hub_dev,
"over-current change on port %d\n",
i);
clear_port_feature(hdev, i,
USB_PORT_FEAT_C_OVER_CURRENT);
hub_power_on(hub, true);
}
I am not sure of the reason for this, but it may be due to over
current requirement of the ralink device which result in it.
If some one face this issue please share. or if any one has solution
for it, I need any advice to avoid this situation,

love. People can only be united if they are free from jealousy, hatred
and petty-mindedness. Purify your heart first. Meet hatred with love
and malice with goodwill. The purer you make your heart, the greater
will be the power of your love.
