Hi,

I have a device (a TomTom GPS) that is seen as a memory device when 
connected via USB.
s
If I plug the device before booting the PC, it is detected and 
accessible via /dev/sdb .
But, if I plug the device after the PC has booted, the device is not 
accessible (the /dev/sdb device is not created). Idem if I disconnect 
and reconnect the device.

I am using a x86 Gentoo system with kernel 2.6.22 (but I have also 
tested kernels 2.6.20 and 2.6.21).

I have already asked for help on the Gentoo forums, but I got no useful 
answer. I hope I'll be more lucky here !

BTW, I have tested the same device on the same computer with Ubuntu 
7.04, and it is working, so it is not a problem with the hardware or the 
device firmware.

Here are the two logs (I have enable the usb-storage debug option in the 
kernel) :

First log (works)
