New description:

 Testing BIOS:Q2B15.
 Testing Image:build212.

 I tried four machines and type "dmesg | grep usb or dmesg | grep usb\ 1-4"
 to see if that problem appears again. But I seemed not to duplicate it
 again on my four OLPC CL1 machines.

 I only know one way to find whether the boot2 code version of  wireless
 module. It's as follows:

 #lsusb -v     //(bcdDevice -> 31.04)

 ...............
 ...............
 Bus 001 Device 003: ID 1286:2001
 Device Descriptor:
   bLength                18
   bDescriptorType         1
   bcdUSB               2.00
   bDeviceClass            0 (Defined at Interface level)
   bDeviceSubClass         0
   bDeviceProtocol         0
   bMaxPacketSize0        64
   idVendor           0x1286
   idProduct          0x2001
   '''bcdDevice           31.04
