Not sure what you mean by usbms, but here's everything dmesg says about the port I've plugged the PW in:

Quote:
usb 1-1.1: default language 0x0409
usb 1-1.1: udev 3, busnum 1, minor = 2
usb 1-1.1: New USB device found, idVendor=1949, idProduct=0004
usb 1-1.1: new USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-1.1: Product: Amazon Kindle
usb 1-1.1: Manufacturer: Amazon
usb 1-1.1: usb_probe_device
usb 1-1.1: configuration #1 chosen from 1 choice
usb 1-1.1: adding 1-1.1:1.0 (config #1, interface 0)
usb-storage 1-1.1:1.0: usb_probe_interface
usb-storage 1-1.1:1.0: usb_probe_interface - got id
scsi6 : usb-storage 1-1.1:1.0
And no, it doesn't seem to unregister.

By USBMS, I meant USB Mass Storage, so I'd be interested in what comes next .

Eh, sorry about being too overly noob Not sure where I'm supposed to look for that. If it's in the dmesg output - I didn't find anything else related.

I'll post an example from my local box ASAP to give you an idea of what it should look like with a 'sane' device (and, specifically, what's interesting in the bunch of info dumped by the kernel) .

Plugged, USBMS

Code:

Eject
Code:

Unplug
Code:
[762221.454887] usb 2-4: USB disconnect, device number 18
Plugged, USBnet
Code:
[762265.939015] usb 2-4: new high-speed USB device number 19 using ehci-pci
[762266.075191] cdc_ether 2-4:1.0 usb0: register 'cdc_ether' at usb-0000:00:1d.7-4, CDC Ethernet Device, ee:49:00:11:08:4d
Note that my kernel is way less verbose because it's not built with verbose/debug USB output (which happens to be the default for a lot of binary distro (i.e. Ubuntu)). [And also potentially worded differently because it's newer].

So, yeah, see if you can spot usb-storage detecting a disk... Barring that, what happens right after the detection of a new USB device.

Sorry, what exactly did you do/run to get that output? I'm still relatively new to linux, so I haven't gotten around all the terminal commands :S

Not necessarily, since I didn't clear the ring buffer (dmesg -c). I just cut and pasted the relevant entries.
