Greetings, my name is Max and i'm having some problems with the usb ports (router has 2 ports) of my router huawei HG553 (bcm63xx) using the openwrt firmware (kernel 3.0.18), looks like that is a common problem with this and similar broadcom based models from huawei (seems that other bcm63xx boards are working fine): 1 port is working at usb 1.1 and the other one is unresponsive, i have tried attaching an usb hub with external power supply, but got the same results. Ports work fine with the original firmware (old kernel 2.6.8.1). Voltage levels (using a multimeter) are ok, with and without an usb device attached. Here is some info with a compiled version using CONFIG_USB_DEBUG: ------ root@OpenWrt:/# dmesg [ 0.000000] Linux version 3.0.18 (max@max-desktop) (gcc version 4.6.3 20120201 (prerelease) (Linaro GCC 4.6-2012.02) ) #1 Thu Mar 15 16:44:18 CET 2012 [ 0.000000] Detected Broadcom 0x6358 CPU revision a1 [ 0.000000] CPU frequency is 300 MHz [ 0.000000] 64MB of RAM installed [ 0.000000] registering 40 GPIOs [ 0.000000] board_bcm963xx: Boot address 0xbe000000 [ 0.000000] board_bcm963xx: CFE version: 100.48.56-48.46 [ 0.000000] bootconsole [early0] enabled [ 0.000000] CPU revision is: 0002a010 (Broadcom BMIPS4350) [ 0.000000] board_bcm963xx: board name: HW553 [ 0.000000] Determined physical RAM map: [ 0.000000] memory: 04000000 @ 00000000 (usable) [ 0.000000] Initrd not found or empty - disabling initrd [ 0.000000] Zone PFN ranges: [ 0.000000] Normal 0x00000000 -> 0x00004000 [ 0.000000] Movable zone start PFN for each node [ 0.000000] early_node_map[1] active PFN ranges [ 0.000000] 0: 0x00000000 -> 0x00004000 [ 0.000000] On node 0 totalpages: 16384 [ 0.000000] free_area_init_node: node 0, pgdat 8027b5d0, node_mem_map 81000000 [ 0.000000] Normal zone: 128 pages used for memmap [ 0.000000] Normal zone: 0 pages reserved [ 0.000000] Normal zone: 16256 pages, LIFO batch:3 [ 0.000000] Reserving 0MB of memory at 0MB for crashkernel [ 0.000000] pcpu-alloc: s0 r0 d32768 u32768 alloc=1*32768 [ 0.000000] pcpu-alloc: [0] 0 [ 0.000000] Built 1 zonelists in Zone order, mobility grouping on.
