1. USB supports hotplugging: you can always safely unplug a usb device. The exact result depends on the device - for eg. USB storage media should be unmounted before unplugging.
2. To check the USB is v2 do dmesg | grep usb
This is what it looks like on my system:
Code:
[simon@indigo-prime simon]$ dmesg | grep usb
usbcore: registered new driver usbfs
usbcore: registered new driver hub
usbcore: registered new driver hiddev
usbcore: registered new driver hid
drivers/usb/input/hid-core.c: v2.0:USB HID core driver
usb 1-3: new high speed USB device using address 2
usbcore: registered new driver usb-storage
on the third line from the bottom see "v2.0:USB" in there?
Now - at the bottom of the post you'll see a bunch of buttons, one says "thank you" - I hope you remembered to click it?
