Yup... that is it-- when it was happening; then after a lot of digging a resident hacker-guru figured out and proved that it was running at USB 1 data-rates-- for whatever reason. What kinda comp are you using Parijat ? Is it a laptop by any chance ? If it's a laptop-- then often, all the USB ports are not USB-2-- sometimes in laptops, one or more ports are USB 1 or USB 1.1 -- maybe it's for for older USB keyboards, mouse etc OR whatever other reason-- but it may be a good idea to first cross-check--- that the port to which you are attaching is a USB 2 port. Aint sure if that'll help.... but that's what I've seen.
