Keydrive crashes USB bus
 

I just bought a new USB flash drive, and despite strange dmesg output, I have managed to get it to work reliably, with only one problem. Sometimes when I plug the keydrive into one my my USB ports, I lose all USB and cannot use either the drive or my (USB) mouse. The only that I know of to fix this is to reboot. (restarting X does not work)

suse 8.2 pro
kernel 2.4.20
This is on an older athlon k7 700 mhz in asus k7v board, of course usb 1.1

strange dmesg output:

As you can see, it repeatedly errors out, but the device is mountable as sda, and I mount it to location /dev/keydrive. I have reliable r/w access.

lsusb output:

Why it shows up as two devices, I know not.

anyway, the problem is, as I said, that sometimes it freezes up my usb altogether, and I cannot figure out why. Any ideas on this would be greatly appreciated, thanks in advance!
