I've just discovered that none of my USB ports appear to be functioning correctly on my Lubuntu install. lsusb shows I have the following:
Bus 002 Device 002: ID 03f0:171d Hewlett-Packard Bluetooth 2.0 Interface [Broadcom BCM2045] Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
So far the only thing I appear to have gotten to detect and work correctly is a usb mouse (below) and my phone will charge (but not be detected) when plugged in.
Bus 002 Device 003: ID 0461:4d64 Primax Electronics, Ltd
Three USB memory sticks I have to hand and a printer I was trying to install don't appear to be detected at all.
Does anyone have any pointers I can try?
