I have 4GB usb andit it is being shown as 2Mb only. Testdisk does show the rest of the space but can't recover it. How can I fix this ?

Looks like a physical problem. If you really need to recover your data, you need to contact a data recovery company specialized in flash memory.

isn't there any way I can recover this partition using testdisk. data is not important but the USB itself is.
