I have this problem with Abit Apollo Pro133x VIA VT82C693A -chipset
while trying to plug in a Kingston 16GB Flash Drive. The chipset is
supporting only USB 1.1 and using UHCI-HCD -driver. I have also Samsung
ML-2010 printer, but it works ok without any problems (whether it's
plugged in or out with Kingston Flashdrive. The error message I get
while plugging in the flash drive is the following:

[ 935.495973] usb 1-1: device descriptor read/64, error -71
[ 935.640251] usb 1-1: device descriptor read/64, error -71
[ 935.942172] usb 1-1: device not accepting address 9, error -71


I get the problem with Ubuntu 8.04 default kernels 2.6.24-16-server and
2.6.24-19-server. I also compiled a vanilla kernel from the
sources (from kernel.org), but it has exactly the same problem. I've
tried the kernel parameter & /sys setting usbcore.autosuspend=-1, but it
doesn't work. I also attached the flash drive to an external hub, but it
doesn't change the situation compared to plugging it in straight.

So it's not limited to EHCI-HCD, the same problem appears also on UHCI-
HCD -driver in the latest kernel.
