Yes, I have already read the Gentoo Linux USB Guide. I have everything required compiled in my kernel. So no problem there. I guess that my system has got a mixture of both USB1.1 and USB2.0 ports. >From the output of lspci: > 00:10.0 USB Controller: VIA Technologies, Inc.

Also, I get this whenever I connect the Pen Drive. But if the message means exactly what it implies, I don't think that it would play a role in slow USB transfers. Device driver target1:0:1 lacks bus and class support for being resumed. > What I don't understand is how come everything works fine in Window? Well Windows surely doesn't display the transfer speeds but the transfers seem to be pretty quick. My friend used a software called Burst copy in Windows, which shows the transfer speed transferred the data at around 8-9MBps. What is the transfer speed that you guys get?
