USB devices not working in GUI

Sat Feb 23, 2013 8:25 am

I have been using my RPi for a while now on Raspbian Linux. Recently, I am not able to use any USB devices once I load the GUI. I am able to login using USB keyboard but after running the startx command and the GUI loads, no USB devices work. I have tested many USB input devices and none work. The ethernet still works and I can verify through SSH. I provide 1.2 Amps of power from my Samsung Galaxy S3 charger and I have tried other power sources over 1 Amp. Any ideas as to why the USB ports stopped working?

If you login what does the command lsusb report? Does if show the devices you expect to see or not.

The OS should respond to the hardware change and load the appropriate drivers etc. for the device to run. If you run

Code: Select all

tail -f /var/log/messages
and then physically remove or add the USB device what messages do you see?

When I use the

Code: Select all

lsusb
command I get this:

Code: Select all

pi@raspberrypi ~ $ lsusb 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp. 
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. 
Bus 001 Device 004: ID 413c:1001 Dell Computer Corp. Keyboard Hub
Bus 001 Device 005: ID 046d:c03d Logitech, Inc. M-BT96a Pilot Optical Mouse
Bus 001 Device 006: ID 413c:2001 Dell Computer Corp. Keyboard HID Support
The wired mouse I am using is Dell but I assume hardware can be made by Logitech. Using the
tail -f /var/log/messages I can see the devices be unpluged showing that the mouse is Logitech. I read other posts about the polyfuses needing time to reset. Could this be the case?

I am having this same issue. During the first boot my wireless Logitech mk260 mouse and keyboard were functioning. After my second boot the keyboard would allow me to login though when the GUI was initiated both the mouse and keyboard would not function. I do see them listed as recognized via the commands listed above. Any suggestions on the next step? I am thinking of flashing the card to start from scratch.. I also added a usb hub in hopes that it would cure what ails me but to no avail.

I switched to the older release of Raspbian and it worked fine. I am using the same mouse.
