I am using Gentoo Linux with 2.6.21-suspend2-r7 kernel. I don't know if I have missed out on some part in kernel compilation, but all USB Transfers seem to be pretty slow. I get an average speed of around 2MBPs and after a while the transfer stalls completely. Not to mention the USB version is 2.0 and the Flash Drives are working very well on Windows. I don't know if this is an issue with Linux in general.
Regards, Amit.

Have you read the Gentoo Linux USB Guide[1]?

And it might help to keep an eye on the logs in general. I generally redirect kern.* to /dev/tty11 and switch to it when I plug the device in.

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. VT82xxxxx UHCI USB 1.1Controller (rev 80) 00:10.1 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1Controller (rev 80) 00:10.2 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1Controller (rev 80) 00:10.3 USB Controller: VIA Technologies, Inc. USB 2.0 (rev 82)
If that is the case, how do I locate the USB 2.0 port on the motherboard?
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?
Regards, Amit.

Open a terminal and post output of:
/sbin/lsmod | grep -e hci -e usb -e sd
Note, you can save outputs to a file:
/sbin/lsmod | grep -e hci -e usb -e sd > lsmod.txt

Check your motherboard manual?
