Pen drive not detecting in Ubuntu12.04

[digambar padulkar]

Dear All
I am having Transcend Pendrive of 8GB, when I open it under windows it
shows the drive, when try to add some files to it it shows its write
protected. When I open it in Ubuntu 12.04 its not detecting the device, but
when I use command "sudo fdisk -l" it shows following

Disk /dev/sda: 40.0 GB, 40020664320 bytes
255 heads, 63 sectors/track, 4865 cylinders, total 78165360 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xfbd911a0

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *        2048    33202175    16600064   83  Linux
/dev/sda2        33204222    78163967    22479873    5  Extended

/dev/sda6        33204224    39063551     2929664   82  Linux swap / Solaris

Partition table entries are not in disk order

Disk /dev/sdb: 8049 MB, 8049917952 bytes*
248 heads, 62 sectors/track, 1022 cylinders, total 15722496 sectors

This doesn't look like a partition table
Probably you selected the wrong device.

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   ?  1936269394  3772285809   918008208   4f  QNX4.x 3rd part
/dev/sdb2   ?  1917848077  2462285169   272218546+  73  Unknown
/dev/sdb3   ?  1818575915  2362751050   272087568   2b  Unknown
/dev/sdb4   ?  2844524554  2844579527       27487   61  SpeedStor

Partition table entries are not in disk order
it shows the USB but not detecting.
*another pen drive it detects automatically
