Our firmware uses standart USB stack, provided by Linux kernel. Nothing should 
be changed in kernel .config to support hub.

Sorry, we are not kernel maintainers and hasn't such hardware for tests.

Seems to be either this hub is buggy, or it is incompatible with WL500W 
hardware.

Thanks for your prompt reply.
Do you have any suggestions for troubleshooting?

For example : loading of a kernel modules.
Here is my output of "lsmod" :

[rumen@WL500W root]$ lsmod

If you haven`t I will kill the fu#$%@g device. :)

Have a nice holidays.

It(hub) requires usbcore+ehci_hcd only. In case of you can't find device in 
/proc/bus/usb/devices and there is no error messages in syslog.log, nothing can 
be done at user level. Kernel hacking process can't be explained in a few words.

Breakthrough.
It exist like that:

#cat /proc/bus/usb/devices
T:  Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#=  1 Spd=480 MxCh= 4
B:  Alloc=  0/800 us ( 0%), #Int=  0, #Iso=  0
D:  Ver= 2.00 Cls=09(hub  ) Sub=00 Prot=00 MxPS=64 #Cfgs=  1
P:  Vendor=1d6b ProdID=0002 Rev= 2.06
S:  Manufacturer=Linux 2.6.22.19 ehci_hcd
S:  Product=EHCI Host Controller
S:  SerialNumber=0000:01:03.2
C:* #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=  0mA
I:* If#= 0 Alt= 0 #EPs= 1 Cls=09(hub  ) Sub=00 Prot=00 Driver=hub
E:  Ad=81(I) Atr=03(Int.) MxPS=   4 Ivl=256ms

BUT when I attached a USB memmory "stick" , who worked before on WL500 , 
nothing changed (syslog.log,dmesg)

attached syslog.log(usb section)
Is it possible power issue?

No, device above is a Virtual hub(EHCI). Real device should look like:

T:  Bus=01 Lev=01 Prnt=01 Port=01 Cnt=02 Dev#=  3 Spd=480 MxCh= 4
D:  Ver= 2.00 Cls=09(hub  ) Sub=00 Prot=01 MxPS=64 #Cfgs=  1
P:  Vendor=0409 ProdID=005a Rev= 1.00
C:* #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=100mA
I:* If#= 0 Alt= 0 #EPs= 1 Cls=09(hub  ) Sub=00 Prot=00 Driver=hub
E:  Ad=81(I) Atr=03(Int.) MxPS=   1 Ivl=256ms

just look at Vendor/ProdID.

So, simplest way is to use another hub.
