I have a 4-port usb hub.If on pc,every thing is ok.
When I use it on my board based mips(big endian),it can be
detected by 2-port hub-on-board.But When I connect some usb
device on this 4-port hub,usb_get_port_status of 4-poprt hub return 0x1010100(should be 0x10101, 0x1010100=le32_to_cpu(0x10101)).
So hub driver think there is nothing connect.
If I connect this usb device directly to 2-port hub, usb_get_port_status of 2-port hub-on-board return 0x10101.
I wonder why 2-port hub and 4-port hub return different port status. Is there big endian hub & little endian hub?
I google for this problem,but get nothing.
BTW,2-port hub is hub on my mips board.linux kernel is linux-2.4.17 from MontaVista.
Sorry for my bad English.
Best regards yfw
